Hi,

Please try another approach which is  shown below.

ASPX:

<MasterTableView DataKeyNames="ID">

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        string Id = item.OwnerTableView.DataKeyValues[item.ItemIndex]["ID"].ToString();
    }
}

Thanks,
Shinu.

Hi,

Unfortunately i couldn't replicate the issue. Here is the sample code I tried to get the DataKeyValue in ItemDataBound event.

ASPX:

<telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" AutoGenerateColumns="false" runat="server" onitemdatabound="RadGrid1_ItemDataBound">
    <MasterTableView DataKeyNames="OrderID">
        <Columns>
            <telerik:GridBoundColumn UniqueName="ShipName" DataField="ShipName"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn UniqueName="ShipCity" DataField="ShipCity"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID"></telerik:GridBoundColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            string strID = item.GetDataKeyValue("OrderID").ToString();
            //OR
            string Id = item.OwnerTableView.DataKeyValues[item.ItemIndex]["OrderID"].ToString();
        }
}

Please provide the code if it doesn't help.

Thanks,
Shinu.

Hello,

Please try with below code snippet/Demo.

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" OnNeedDataSource="RadGrid1_NeedDataSource"

           <MasterTableView CommandItemDisplay="Top" DataKeyNames="ID">
               <Columns>

        {
            GridDataItem item = (sender as RadButton).NamingContainer as GridDataItem;
            string strId = item.GetDataKeyValue("ID").ToString();
        }

            dynamic data = new[] {
              new { ID = 1, Name ="aaa"},

            RadGrid1.DataSource = data;
        }

Hai all..................

in radgrid Itemcommand Event i am getting GetDataKeyValue and i am storing it in session after doing some operations like update and delete for some other divisions i am rebinding this grid.after doing rebind also i need that selected row only for that in itemdatabound i  write the code like if session is equal to null then only it will go to that code are else it will select by defalut 1st row only.if session not equal to null then it will check

GridDataItem item = e.Item as GridDataItem;
       if(item.OwnerTableView.DataKeyValues[item.ItemIndex]["ID"].ToString()==Session["id"])
                  item.SelecteValue=true;
so it will stay in perticular row only but in item.OwnerTableView.DataKeyValues[item.ItemIndex]["ID"].ToString() i am getting 1st row value if i select 2nd row also. in itemcommand i am getting 2nd row id and i am storing it in session but it is not comparing to itemdatabound value how to set selected row only afeter doing rebind also in itemdatabound

Hi,

Can someone please help me on how to Radgrid2 Data key Values in Radgrid1? Radgrid2 has a detail table. When I try the code below I get error saying 
'Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index'

 

Protected Sub Radgrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound
       
        If (TypeOf e.Item Is GridDataItem) Then
            Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)
            Dim strSidPartNum As String = RadGrid1.MasterTableView.DataKeyValues(e.Item.ItemIndex)("SID_PART").ToString
            Dim strLoadPartNum As String = RadGrid2.MasterTableView.DataKeyValues("LOAD_PART").ToString
            Dim strTotalQty As String = RadGrid2.MasterTableView.DataKeyValues(e.Item.ItemIndex)("LOAD_PART_SUM").ToString
            Dim strQtyExp As String = RadGrid1.MasterTableView.DataKeyValues(e.Item.ItemIndex)("QTY_EXP").ToString

            'FORMATTING to a different color to highlight the part num and quantity variation between the SID and LOADS side
            If strSidPartNum = strLoadPartNum Then
                If strTotalQty <> strQtyExp Then
               
                    dataItem.ForeColor = Color.Red
 
                Else
                 
                End If
            End If
        End If

 

Thank you.
