Selected items' values always return null

[Ugur]

Hi,

When i want to get radgrid selected items, I show that all the cells' values are null. I applied the solutions below but they didn't work.

Please help for getting selected row values.

*******
  GridDataItem[] itemm = grdWorkReport.MasterTableView.GetSelectedItems();
        string ss = itemm[0]["CalismaTarihi"].Text;   ( --->>> ss  Returns null )

******
 foreach (GridDataItem item in grdWorkReport.SelectedItems)
        {
            Response.Write(item["CalismaTarihi"].Text.ToString()); // CustomerID is the uniquename of column 
        }
*******

My radgrid is :

  <telerik:RadGrid ID="grdWorkReport" Skin="Sitefinity" runat="server" AllowPaging="True"   SelectedItemStyle-BackColor="Orange"
            AutoGenerateColumns="False" CellSpacing="0" GridLines="None" Height="350px" OnNeedDataSource="RadGrid1_NeedDataSource" OnItemDataBound="RadGrid1_ItemDataBound"

              </telerik:GridTemplateColumn>

Hi Ugur,

Unfortunately I couldn't replicate the issue. Here is the sample code snippet I tried  to get the text of  a cell  in a selected row on a button click event . I guess the column you are accessing is a GridBoundColumn.

ASPX:

<telerik:RadGrid ID="grdWorkReport" runat="server" AllowPaging="True" PageSize="5"
    Skin="Hay" DataSourceID="SqlDataSource1" AllowMultiRowSelection="true" AutoGenerateColumns="false">
    <MasterTableView>
        <Columns>
            <telerik:GridBoundColumn DataField="OrderID" UniqueName="CalismaTarihi">
            </telerik:GridBoundColumn>
            <telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">
                <ItemTemplate>
                    <asp:CheckBox ID="CheckBox1" runat="server" OnCheckedChanged="ToggleRowSelection"
                        AutoPostBack="True" />
                </ItemTemplate>
                <HeaderTemplate>
                    <asp:CheckBox ID="headerChkbox" runat="server" OnCheckedChanged="ToggleSelectedState"
                        AutoPostBack="True" />
                </HeaderTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView></telerik:RadGrid>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" />

C#:

protected void Button1_Click(object sender, EventArgs e)
{
    foreach(GridDataItem item  in grdWorkReport.SelectedItems)
    {
        string Selected = item["CalismaTarihi"].Text.ToString();
    }
}

Please elaborate the scenario if it doesn't help.

Thanks,
Princy.

Hi Princy,

Thank you for your answer but it didn't  work for me. The columns are GridTemplateColumn and first i select a row, then click a button to get selected column values.

My gridview and C# codes are above.

Hello,

Please try with the below code snippet.

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

protected void ToggleRowSelection(object sender, EventArgs e)
    {
        CheckBox chk = sender as CheckBox;
        GridDataItem item = chk.NamingContainer as GridDataItem;
        item.Selected = chk.Checked;
    }

Thanks,

Thank you. I solved.

It is very easy actually. 

To get values I must use item.FindControl() and get the value. Because i use GridTemplateColumn.

Label lblid = item.FindControl("lblid") as Label

lblid.Text = ....

like this.

Hi Bharath,

You can try the following code snippet to get the selected rows values:

ASPX:

<MasterTableView DataKeyNames="OrderID">
  <ClientSettings EnablePostBackOnRowClick="true" Selecting-AllowRowSelect="true"> </ClientSettings>

C#:

protected void RadGrid1_SelectedIndexChanged1(object sender, EventArgs e)
{
 foreach (GridDataItem selectedItem in RadGrid1.SelectedItems)
 {
  string value = selectedItem.GetDataKeyValue("OrderID").ToString(); //Get the selected row datakey value
 }
}

Thanks,
Shinu
