Getting the file UploadControlId in NestedViewTemplate in Telerik Grid

[Sailaja]

Hi,
I am using a telerik grid in which I have a NestedViewTemplate
In that I have a file upload control.
I just want to get the upload Control ID and the filename that is being uploaded once the "Upload" button is clicked.
How can I get it?
Under which event I can get it?

Here is my sample code:

<telerik:RadGrid ID="radgrdFiles"  runat="server"....>
<MasterTableView>

<NestedViewTemplate>

<asp:FileUpload ID="UploadFile" runat="server">

<asp:ImageButton ID="imgbtnUpload" runat="server"  CommandName="Upload"onclick="imgbtnUpload_Click">
</NestedViewTemplate>

</MasterTableView>
<Columns>
....
</Columns>
</telerik:RadGrid>
I m not able to get it in button_Click event.
Thanks in advance...

Hello Sailaja,

You can try the following:

1) Add handler for the Grid ItemCommande event
2) Once there, check whether the current command is Upload
3) If so, use e.Item.FindControl in order go grab an instance of the upload.

RadUpload upload = e.Item.FindControl("RadUpload1") as RadUpload;

Thank you.
Its working fine.
But, I got one more issue.
I am using the detailstable instead of NestedViewTemplate.
Here,when I clicked on Expand/Collapse button of radgrid, uploaded the file and I just want to rebind the nested grid with the newly added file.
But, I am not able to get it.(Actually it is updated in DB and the child grid is not rebinded to get the new file).
Its working fine once i navigated to mastergrid and then this nested grid.
I wrote in PreRender event as

 

protected void RadGrdFilesPro_PreRender(object sender, EventArgs e)

{

 

 

 

 

if (!Page.IsPostBack)  

{ 

 

    this.RadGrdFilesPro.MasterTableView.Rebind(); }

 

}
If i dint write rebind() in !Postback(), i am unable Exp/collapse button is not working.
Any alternative to fix this issue please.

Hi Sailaja,

Why do you use !Page.IsPostback? This will execute the rebind code only on initial page_load. It wound execute it after a file has been uploaded because it is a postback. Could you please try remove !Page.IsPostback and try again?
