I am trying to create a file upload control dynamically for updating word documents. I have the following code in my aspx page.
<asp:GridView ID="gvDetails" runat="server" AutoGenerateColumns="false" DataKeyNames="FilePath" EmptyDataText="No documents attached" >
<HeaderStyle BackColor="Purple" Font-Bold="true" ForeColor="White" />
<Columns>
<asp:TemplateField HeaderText="FilePath">
<ItemTemplate>
<asp:LinkButton ID="lnkDownload" runat="server" Text="My Document" OnClick="lbDownloadDocument_Click"></asp:LinkButton>
<img src="Image/delete.jpg" alt="" onclick="AddFile()" /><br />
<br />
<asp:Button ID="Button1" runat="server" Text="Update" OnClick="Button2_Click" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
I have the following code in my .cs page.
protected void Button2_Click(object sender, EventArgs e)
{
for (int i = 0; i < Request.Files.Count; i++)
{
HttpPostedFile PostedFile = Request.Files[i];
if (PostedFile.ContentLength > 0)
{
string FileName = System.IO.Path.GetFileName(PostedFile.FileName);
PostedFile.SaveAs(Server.MapPath("~/Files/") + FileName);
}
}
}
And my script is :
<script type="text/javascript">
var i = 1;
function AddFile() {
i++;
var div = document.createElement('DIV');
div.innerHTML = '<input id="file' + i + '" name = "file' + i + '" type="file" /><img src="~/Image/delete.jpg" alt="Remove" onclick = "RemoveFile(this)" />';
document.getElementById("divFile").appendChild(div);
}
function RemoveFile(file) {
document.getElementById("divFile").removeChild(file.parentNode);
}
</script>
But Somehow this code is not working. I don't have much idea of file upload control. Please help me with it. Should I use an Update panel ?

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();
}
}
}

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..

Forgive my English, I had one challenge in my project I,e whenever I started to access hidden field value which in grid view using JavaScript or Jquery, I'm getting compilation error like hidden field doesn't exist in current context so how can I access hidden field value?

}
} catch (Exception ex) {
}
}
I'm not sure the code
document.getElementById("<%=PatientRefferalId.ClientID%>")
will work, because you don't have only one "PatientRefferalId", but you get many (as many as numbers of rows in your gridview).
I don't know if there is a cleaner way, but I can do what you want by using this javascript code
var gv = document.getElementById("<%=gvPatient.ClientID%>");
var Rows = gv.getElementsByTagName("tr"); // Get all the rows from your gridview (rendered as html table).
// you can loop through the rows or if you know the row index, you can do:
alert(Rows[2].childNodes[0].children[0].value); // Show you the first control (the hiddenfield) of the first cell of the row #2.
Hi This post may help you.
var c = document.getElementsByTagName("table");
for (var i = 0; i < c.length; i++) {
if (c[i].id.indexOf("GridView1") > -1) {
var hidd = c[i].getElementsByTagName("input");
for (var j = 0; j < hidd.length; j++) {
if (hidd[j].type == "hidden")
alert(hidd[j].id);
}
}
}
And also refer following link .. its working to me..

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:TextBox ID="TextBox1" runat="server"></asp:TextBox>

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 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" >

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>
