Out of Range Exception

[Animesh]

Hi I am new to programming. My requirement is limited. My radgrid is populated with data using stored procedure. Now when I wants to view the data I am getting out of range exception. The exception is thrown on SelectedIndexChanged event.The code is as follows:

 

Aspx:

Loading the radgrid
TGRCircularAIBOC.DataSource = Resources.GetCircular("AIBOC");
            TGRCircularAIBOC.DataBind();

<telerik:RadGrid ID="TGRCircularAIBOC" runat="server" Skin="Office2007" OnSelectedIndexChanged="TGRCir

protected void TGRCircularAIBOC_SelectedIndexChanged(object sender, EventArgs e)
    {
        GridDataItem dataitem = (GridDataItem)TGRCircularAIBOC.SelectedItems[0];
        string CircularNo = dataitem["CircularNo"].ToString();
        string AuthorityCode = "AIBOC";
        byte[] BinaryPDF = Resources.ViewCircular(CircularNo, AuthorityCode);
        Response.Clear();
        Response.ClearContent();
        Response.ClearHeaders();
        Response.ContentType = "application/pdf";
        Response.AddHeader("content-disposition", "attachment; filename = " + "Circular");
        Response.BufferOutput = true;
        Response.BinaryWrite(BinaryPDF);
        Response.Flush();
        Response.End();
    }
Actually I am trying to display a pdf here which is fetched in varbinary format...

cularAIBOC_SelectedIndexChanged">  

                        <ClientSettings Selecting-AllowRowSelect="true" EnablePostBackOnRowClick="true" ></ClientSettings>

                    </telerik:RadGrid>

Hi Animesh,

Have you had the chance to try out the suggested solution or test the sample I've attached in the other forum thread (SelectedIndexChanged event of RadGrid)?

Also, to get the cell value use the text property of the Cell. (Accessing Cells Using Column Unique Name)

string CircularNo = dataitem["CircularNo"].Text.ToString();

Additionally, you might use a condition that will count the selected items and only run the logic if there is at least one item in the collection.

protected void RadGrid1_SelectedIndexChanged(object sender, EventArgs e)
{
    if(TGRCircularAIBOC.SelectedItems.Count > 0){
        GridDataItem dataitem = (GridDataItem)TGRCircularAIBOC.SelectedItems[0];
        // do something
    }
}

Give the suggestion above a try to see if that works for you.

Kind regards,
Attila Antal
