Calling a java script function in grid view button field

I have a asp.net grid view which has a buttonfield to reset a user? I need to call a js function to get a confirmation message, when the buttonfield clicks, Any ideas? TIA
here is my grid view
<asp:GridView ID="grdAllProducts" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" GridLines="None" Width="100%" OnRowCommand="grdAllProducts_RowCommand">
<AlternatingRowStyle BackColor="White" />
<Columns>
<asp:BoundField DataField="USER_ID" HeaderText="User ID" />
<asp:BoundField DataField="USER_NAME" HeaderText="User Name" />
<asp:BoundField DataField="EMAIL" HeaderText="E-mail" />
<asp:BoundField DataField="PHONE_NUMBER" HeaderText="Phone No." />
<asp:BoundField DataField="USER_ROLE_NAME" HeaderText="User Role" />
<asp:ButtonField ButtonType="Button" Text="Reset" />
</Columns>
<EditRowStyle BackColor="#7C6F57" />
<FooterStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#666666" ForeColor="White" HorizontalAlign="Center" />
<RowStyle BackColor="#E3EAEB" />
<SelectedRowStyle BackColor="#C5BBAF" Font-Bold="True" ForeColor="#333333" />
<SortedAscendingCellStyle BackColor="#F8FAFA" />
<SortedAscendingHeaderStyle BackColor="#246B61" />
<SortedDescendingCellStyle BackColor="#D4DFE1" />
<SortedDescendingHeaderStyle BackColor="#15524A" />
</asp:GridView>
here is my js function
function validateResetButton() {
if (confirm('Are you sure you want to Reset this User?')) {
return true;
}
else {
return false;
}
}

This works for me...
Add commandname in buttonfield
<asp:ButtonField ButtonType="Button" Text="Reset" CommandName="Reset" />
Add rowdatabound to gridview control
protected void grdAllProducts_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// if you dont want the for loop directly put the button index
for (int i = 0; i < e.Row.Cells.Count; i++)
{
foreach (Button button in e.Row.Cells[i].Controls.OfType<Button>())
{
if (button.CommandName == "Reset")
{
button.Attributes["onclick"] = "if(!confirm('Do you want to Reset ?')){ return false; };";
}
}
}
}
}

in most cases, it MUCH easer to just drop in a regular plain jane button.
So, say we have this simple GV.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"
CssClass="table table-hover table-striped" Width="50%"
DataKeyNames="ID">
<Columns>
<asp:BoundField DataField="FirstName" HeaderText="FirstName" />
<asp:BoundField DataField="LastName" HeaderText="LastName" />
<asp:BoundField DataField="City" HeaderText="City" />
<asp:BoundField DataField="HotelName" HeaderText="HotelName" />
<asp:BoundField DataField="Description" HeaderText="Description" />
<asp:TemplateField ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Button ID="cmdDel" runat="server" Text="Delete" CssClass="btn" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
And code to load:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
LoadGrid();
}
void LoadGrid()
{
using (SqlConnection conn = new SqlConnection(Properties.Settings.Default.TEST4))
{
string strSQL = "SELECT * FROM tblHotelsA ORDER BY HotelName";
using (SqlCommand cmdSQL = new SqlCommand(strSQL, conn))
{
DataTable rstData = new DataTable();
conn.Open();
rstData.Load(cmdSQL.ExecuteReader());
GridView1.DataSource = rstData;
GridView1.DataBind();
}
}
}
And we now have this:
So, lets now add a click event to the button.
so, we have now this:
<asp:TemplateField ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Button ID="cmdDel" runat="server"
Text="Delete"
CssClass="btn"
onclick="cmdDel_Click"
onclientClick="return confirm('really delete this?');"
/>
</ItemTemplate>
</asp:TemplateField>
And our code behind click event?
Say this:
protected void cmdDel_Click(object sender, EventArgs e)
{
Button btnDel = (Button)sender;
GridViewRow gRow = (GridViewRow)btnDel.NamingContainer;
// get PK id of row
// (note how this is hidden - NEVER exposed client side
int PKID = (int)GridView1.DataKeys[gRow.RowIndex]["ID"];
Debug.Print("Row index click = " + gRow.RowIndex);
Debug.Print("pk row id for click = " + PKID);
string strSQL = "DELETE FROM tblHotelsA WHERE ID = #ID";
using (SqlConnection conn = new SqlConnection(Properties.Settings.Default.TEST4))
{
using (SqlCommand cmdSQL = new SqlCommand(strSQL, conn))
{
conn.Open();
cmdSQL.Parameters.Add("#ID", SqlDbType.Int).Value = PKID;
cmdSQL.ExecuteNonQuery();
}
}
}

how to get selected value in javascript from dropdownlist of gridview

How to retrieve the value of dropdownlist [ddrateplan] in below javascript and the dropdown is located in gridview [DataExtensionList].
<asp:GridView ID="DataExtensionList" Width="100%" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="Service No.">
<ItemTemplate>
<asp:HiddenField ID="hdid" runat="server" Value='<%#Eval("tran_id") %>' />
<asp:DropDownList ID="drpphn" runat="server" CssClass="form-control" AutoPostBack="true"
OnSelectedIndexChanged="drpphn_SelectedIndexChanged" SelectedValue='<%# Eval("phone_no") %>'>
<asp:ListItem Value="0">Existing no</asp:ListItem>
<asp:ListItem Value="1">New no</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="txtservicenumber" runat="server" Text='<%#Eval("service_number") %>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Rate Plan">
<ItemTemplate>
<asp:DropDownList ID="ddrateplan" runat="server" CssClass="form-control" AutoPostBack="true" onchange="mul();"
OnSelectedIndexChanged="ddrateplan_SelectedIndexChanged"
Style="margin: 0 !important; padding: 0 !important;" SelectedValue='<%# Eval("rate_plan") %>'>
<asp:ListItem Value="0">Select Rate Plan</asp:ListItem>
<asp:ListItem Value="35">p35</asp:ListItem>
<asp:ListItem Value="59">p59</asp:ListItem>
<asp:ListItem Value="89">p89</asp:ListItem>
</asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Address">
<ItemTemplate>
<label>
<asp:TextBox ID="txt_address" AutoPostBack="true" runat="server" Text='<%# Eval("address")%>'></asp:TextBox>
</label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
this is the example of javascript i have tried but it is not working..
<script type="text/javascript">
function mul() {
var gv = document.getElementById("<%=DataExtensionList.ClientID %>");
var dropvalue = gv.getElementsByTagName('ddrateplan');
var rowcount = document.getElementById('<%=DataExtensionList.ClientID%>').rows.length;
var textmonth = document.getElementById('<%=txtcontactperiod.ClientID%>').value;
var total = 0;
for (var i = 0; i < rowcount - 1; i++) {
total += parseInt(dropvalue) * parseInt(textmonth)
}
if (textmonth > 0) {
$("<%=hdvalue.ClientID%>").val(total);
document.getElementById('<%=txttotalpayble.ClientID%>').value = total;
}
else {
$("<%=hdvalue.ClientID%>").val("");
document.getElementById('<%=txttotalpayble.ClientID%>').value = '';
}
}
</script>

i got my answer just add property of dropdown [ddrateplan] as clientidmode="static" and replace the javascript's line
var gv = document.getElementById("<%=DataExtensionList.ClientID %>");
var dropvalue = gv.getElementsByTagName('ddrateplan');
with this
var dropvalue = $("#ddrateplan").val();

I need to export the nested child gridview to excel with grouping (subtotal, Grand total), but when I export grouping row is only a blank row, so I try this code but it cannot work with nested gridview
So how to do, because when debugging, null value error occur. I think because Hidden Field value is null and I cannot get the div forExport in the Parent Gridview.And this is the code behind:
public override void VerifyRenderingInServerForm(Control control)
{
/* Confirms that an HtmlForm control is rendered for the specified ASP.NET
server control at run time. */
}
protected void ExportExcel(object sender, EventArgs e)
{
grvPayroll.AllowPaging = false;
var grvPayrollDetails = new GridView();
for (var i = 0; i < grvPayroll.Rows.Count; i++)
{
grvPayrollDetails = (GridView) grvPayroll.Rows[i].FindControl("grvPayrollDetails");
}
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=PayrollExport.xls");
Response.Charset = "UTF-8";
Response.ContentType = "application/vnd.ms-excel";
using (var sw = new StringWriter())
{
grvPayrollDetails.AllowPaging = false;
BindGrid(SortField);
grvPayrollDetails.Font.Name = "Times New Roman";
grvPayrollDetails.BackColor = Color.Transparent;
grvPayrollDetails.GridLines = GridLines.Both;
grvPayrollDetails.HeaderStyle.VerticalAlign=VerticalAlign.Middle;
sw.Write(System.Web.HttpUtility.HtmlDecode(hidGridView.Value));
Response.Write(Regex.Replace(sw.ToString(), "(<a[^>]*>)|(</a>)", " ", RegexOptions.IgnoreCase));
Response.Flush();
Response.End();
}
}
I referred this link :Exporting to Excel from GridView when grid changed by code behind

For accessing id of asp.net controls you have to use ClientID as below
document.getElementById('<%=hidGridView.ClientID%>').value = htmlEscape(document.getElementById("forExport").innerHTML);

While calculating total of gridview cell using javascript and jquery getting error

I am calculating the total of GridView cells using java script and jquery. But, I am always getting this error while compiling.
The name 'total' does not exist in the
current context
Inside GridView code:
<asp:TemplateField HeaderText="Header 1">
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</ItemTemplate>
<FooterTemplate>
<asp:Label ID="lblTotal" runat="server" Text="Total" Font-Bold="true">
</asp:Label>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Header 2" >
<ItemTemplate>
<asp:TextBox ID="TextBox2" runat="server" class="calculate"
onchange="calculate()"></asp:TextBox>
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="total" runat="server"></asp:TextBox>
</FooterTemplate>
javascript and jquery code:
<script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js"
type="text/javascript">
<script language="javascript" type="text/javascript">
function calculate()
{
var txtTotal = 0.00;
//var passed = false;
//var id = 0;
$(".calculate").each(function (index, value) {
var val = value.value;
val = val.replace(",", ".");
txtTotal = MathRound(parseFloat(txtTotal) + parseFloat(val));
});
document.getElementById("<%=total.ClientID %>").value = txtTotal.toFixed(2);
}
function MathRound(number) {
return Math.round(number * 100) / 100;
}
</script>
how can I solve this issue any help pls.

You can't access controls inside templated controls like GridView that easily. Create some variable to hold total.ClientID so that jQuery can grab it.
In your aspx:
var totalClientID = TotalClientID;
In codebehind:
void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.Footer)
{
TotalClientID = ((TextBox)e.Row.FindControl("total")).ClientID;
}
}

<script language="javascript" type="text/javascript">
function Calculate() {
var grid = document.getElementById("<%=grid.ClientID%>");
var sum = 0;
for (var i = 1; i < grid.rows.length; i++) {
var Cell = grid.rows[i].getElementsByTagName("input");
if (!Cell[4].value) {sum += 0; } else { sum += parseFloat(Cell[0].value);}
}
alert(sum);
}
</script>
<asp:TemplateField HeaderText="Current payment" >
<ItemTemplate>
<asp:TextBox ID="txtvalue" runat="server" Width="70px" BorderStyle="None" onkeyup="Calculate();" ></asp:TextBox>
</ItemTemplate>
<ItemStyle Width="120px" />
</asp:TemplateField>`enter code here`

I think you've already realised that RadioButtonList controls are rendered as a <table> with each radio button as an <input> within that table. Therefore getting a handle on RadioButtonList1 and trying to access it as an array using MyRadio[j] isn't going to work.
I think the following line:
var options = document.getElementsByTagName("input")
Should instead read:
var options = MyRadio.getElementsByTagName("input")
That will give you just a collection of the input tags within that RadioButtonList control rather than all those on the page. Once you have that options collection, you shouldn't need to refer to the RadioButtonList control again.
I understand that this is drastically simplified over what you have, but here's an example for you:
<form runat="server">
<asp:RadioButtonList runat="server" id="RadioButtonList1">
<asp:ListItem>Yes</asp:ListItem>
<asp:ListItem>No</asp:ListItem>
<asp:ListItem>N/A</asp:ListItem>
</asp:RadioButtonList>
<input type="button" onclick="fcnUpdateMain()" value="Click" />
<script type="text/javascript">
function fcnUpdateMain()
{
var MyRadio = document.getElementById("<%=RadioButtonList1.ClientID%>")
var options = MyRadio.getElementsByTagName("input")
var somethingChecked = false;
for( x = 0; x < options.length; ++x )
{
if (options[x].checked)
{
somethingChecked = true;
}
}
if (!somethingChecked)
{
alert("You must select an answer for all questions.")
return false;
}
}
</script>
</form>
