Button in column to open radWindow

[Declan]

I am using a radGrid for Customer Orders. To each order I can attach uploaded files. Because I was having difficulties with radUpload and Ajax I decided to do the uploading using a radWindow.

Two pieces of information are required to attach the uploaded documents to the Order; CustomerID and OrderID.

I assign the CustomerID to a hidden field in the ItemDataBound event of the grid.

The grid uses GridTemplateColumn with teh "form fields" laid out in this single column. A second GridTemplateColum is used for the button to attach files:

<telerik:GridTemplateColumn UniqueName="GridTemplateColumn" HeaderText="GridTemplateColumn">
    <ItemTemplate>
        <button id="btnShowDlg" onclick="showDialog();return false;" type="submit">Click here to attach files</button>
    </ItemTemplate>
</telerik:GridTemplateColumn>

RadWindow manager is used to open a window passing the CustomerID as an argument from the hidden field. This works fine.

Where I run into trouble is trying to get the OrderID from the grid row on which the button was clicked. I have tried various methods using Javascript found on this site without success.

Using OnClick on the button allows me open the window and pass the CustomerID as an argument but I just can't figure out how to get the OrderID from the row whose button was clicked.

All suggestions welcome.

Hello Declan,

You can try the following code to achieve the required scenario.
aspx:

<telerik:GridTemplateColumn UniqueName="GridTemplateColumn" HeaderText="GridTemplateColumn">
     <ItemTemplate>
         <input runat="server" id="Submit1" type="submit" value="Click here to attach files"  />
     </ItemTemplate>
</telerik:GridTemplateColumn>

cs:

 protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
      if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            string strtxt = item["CustomerID"].Text;
            string strtxt2=item["OrderID"].Text;
            HtmlInputSubmit btn = (HtmlInputSubmit)item["GridTemplateColumn"].FindControl("Submit1");
            btn.Attributes.Add("onclick", "return ShowDialog('" + strtxt + "','" + strtxt2 + "');");

        }
    }

js:

function  ShowDialog(CustomerID,OrderID)
 {
    var Wnd = radopen("Default.aspx?Customer ID=" + CustomerID+ "& Order ID=" +OrderID, "RadWindow1" );
   return false;
 }

Thanks

Hi Princy,

Thanks, that works a treat :)

One minor problem:- I don't seem to be able to reference the upload.aspx.

All I can get to work is the full path to the file within the application. This is part of a DotNetNuke module but I don't think that is relevant.

var Wnd = window.radopen("/dnn4/DesktopModules/testUpload/Upload.aspx?CUID=" + CustomerID + "&ORID=" + OrderID, "RadWindow1");

Folder structure

dnn4
-    bin
-    DesktopModules
- -        testUpload

While this allows the app to work it means having to change the ascx when moving to production. It would be nice if I could get a relative reference to work. What have I missed?

Thanks,
Declan

Solution:

Dim btn As HtmlInputSubmit = DirectCast(item("GridTemplateColumn").FindControl("Submit1"), HtmlInputSubmit)

Dim sFileToOpen As String = ResolveUrl("Upload.aspx") & "/Upload.aspx"
Dim sAttributes As String

sAttributes = "return ShowUpload('" + sFileToOpen + "','" + strtxt + "','" + strtxt2 + "');"
btn.Attributes.Add("onclick", sAttributes)

Thanks.
