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);

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();

One more Important point is i am not getting any error

The way you're doing it is very complicated and it really doesn't need to be this way.You can create a hidden column in your GridView and bind it to the required property on your datasource which contains the details data.Then using very minimal jQuery you can loop through the rows of the GridView -> extract the hidden comment -> set the tooltip of the row hover to this value or create some other event that shows a custom popup div with your comment.
Look how simple this is:
Code behind:
public partial class aGridViewDetailsHover : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
GridView1.DataSource = this.GetUsers();
GridView1.DataBind();
}
}
private List<MyUser> GetUsers()
{
var u1 = new MyUser { Name = "User1 Name", Surname = "User1 Surname", HiddenComment = "Hidden Comment For User 1" };
var u2 = new MyUser { Name = "User2 Name", Surname = "User2 Surname", HiddenComment = "Hidden Comment For User 2" };
var u3 = new MyUser { Name = "User3 Name", Surname = "User3 Surname", HiddenComment = "Hidden Comment For User 3" };
return new List<MyUser> { u1, u2, u3 };
}
}
public class MyUser
{
public string Name { get; set; }
public string Surname { get; set; }
public string HiddenComment { get; set; }
}

}

Now, I try to get the RadGrid -- EditItemTemplate -- Button control
inside JavaScript to make it visible true/false based on text length that user enter in RadComboBox.
Below is my JavaScript:
<script lang="javascript" type="text/javascript">
function OnClientTextChange(sender, eventArgs) {
//alert("You typed " + sender.get_text());
var len = sender.get_text().length;
alert(len);
var form = $find("<%#RGGSTAcCode.ClientID%>").get_masterTableView();
alert(form);
}
</script>
When I run my web page, I always get below error:
The name 'RGGSTAcCode' does not exist in the current context
I tried to change the JavaScript code as below:
var form = document.getElementById('<%=fvIPRForm.FindControl("RGGSTAcCode").ClientID%>');
var masterTable = form.get_masterTableView();
alert(masterTable);
but then I get [object Object] in "alert". What is wrong in my code?
Edit
Tried below solution, all working except Buttons are not disabled/enabled inside if/else:
function onTextChange(sender, args) {
//alert("You typed " + sender.get_text());
var len = sender.get_text().length;
alert(len);
var comboID = sender.get_id();
var btnSearchID = comboID.replace("ddlAccountCode", "btnSearch");
alert("Alert 1: " + btnSearchID); //getting : contentplaceholder_fviIPRForm_RGGSTAcCode_btnSearch
var btnCtrl = $get(btnSearchID);
alert("Alert 2: " + btnCtrl); //getting : [object HTMLInputElement]
if (len > 5)
{
alert("greater");
btnCtrl.set_enabled(true);
btnsearch.set_enabled(true); // enable search button
}
else
{
alert("less");
btnCtrl.set_enabled(false);
btnsearch.set_enabled(false); // disable search button
}
}

This might be the answer you want....
Not the best but is working..

make calculation inside the gridview

I have these two itemtemplates of textboxes inside the gridview and i am trying to make calculation between them but is not working inside the grid.here is my code
<asp:TemplateField HeaderText="Net Weight">
<ItemTemplate>
<asp:TextBox ID="txtNetWT" runat="server" Width="70px" AutoPostBack=false></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Rate">
<ItemTemplate>
<asp:TextBox ID="txtRate" runat="server" Width="70px" ></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="SNF">
<ItemTemplate>
<asp:TextBox ID="txtSNF" runat="server" Width="70px" ></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="FAT">
<ItemTemplate>
<asp:TextBox ID="txtFat" runat="server" Width="70px" ></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="LR">
<ItemTemplate>
<asp:TextBox ID="txtLR" runat="server" Width="70px"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="14 TS">
<ItemTemplate>
<asp:TextBox ID="txtTS" runat="server" Width="70px" ></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
But When I enter the value this make no effect to other element.Please tell me any proper function in Javascript to do this.

Only change the aspx.cs page "onkeyup"
txtFATObj.Attributes.Add("onkeyup", "Calculate('" + txtFATObj.ClientID + "','" + txtSNFObj.ClientID + "','" + txtNETWTObj.ClientID + "','" + txtTSObj.ClientID + "')");

Please check the following codes. Note you need to adjust.. integer or float.. etc. I tested some calculation based on your fomula.
-- to put in javascript section inside head
<script type="text/javascript" language="javascript">
function Calculate(txtFAT, txtSNF, txtNETWT, txtTS) {
var txtFATObj = document.getElementById(txtFAT);
var txtSNFObj = document.getElementById(txtSNF);
var txtNETWTObj = document.getElementById(txtNETWT);
var txtTSObj = document.getElementById(txtTS);
if (txtFATObj != null && txtSNFObj != null && txtNETWTObj != null && txtTSObj != null) {
txtTSObj.value = parseFloat(txtFATObj.value) + (parseFloat(txtSNFObj.value) * parseFloat(txtNETWTObj.value) / 14);
}
}
</script>

dr[0] = "Item 3";
dt.Rows.Add(dr);
grvCalc.DataSource = dt;
grvCalc.DataBind();
}
-----need to attach client side event of each text control for calcuation involvement
-- gridvew row data bound event .. calculation will perform onfoucus event of text box
protected void grvCalc_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox txtFATObj = (TextBox)e.Row.FindControl("txtFAT");
TextBox txtSNFObj = (TextBox)e.Row.FindControl("txtSNF");
TextBox txtNETWTObj = (TextBox)e.Row.FindControl("txtNETWT");
TextBox txtTSObj = (TextBox)e.Row.FindControl("txtTS");
txtFATObj.Attributes.Add("onfocusout", "Calculate('" + txtFATObj.ClientID + "','" + txtSNFObj.ClientID + "','" + txtNETWTObj.ClientID + "','" + txtTSObj .ClientID + "')");

txtNETWTObj.Attributes.Add("onfocusout", "Calculate('" + txtFATObj.ClientID + "','" + txtSNFObj.ClientID + "','" + txtNETWTObj.ClientID + "','" + txtTSObj.ClientID + "')");
}
}

This should work:
onkeydown="document.getElementById('<%= txtRate.ClientID %>').value=this.value;"

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>
