Hi
how to find row values of a selected row in a radgrid? c#
I have a radbutton inside a radgrid.
<telerik:RadGrid ID="dg" runat="server" AllowSorting="true" Width="100%"
RenderMode="Auto" PageSize="10" AutoGenerateColumns="false"
AllowPaging="true">
<PagerStyle Mode="NextPrevAndNumeric" Position="TopAndBottom" PageSizeControlType="RadComboBox"
AlwaysVisible="true"></PagerStyle>
<MasterTableView HierarchyDefaultExpanded="false">
<CommandItemSettings AddNewRecordText="Nuevo" CancelChangesText="Cancelar" RefreshText="Actualizar"
ShowRefreshButton="false" />
<Columns>
<telerik:GridTemplateColumn HeaderText="Id" Visible="false">
<ItemTemplate>
<asp:Label ID="lblID" runat="server" Text='<%# Eval("Idtip") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:Label ID="lblIDEd" runat="server" Text='<%# Eval("Idtip") %>' Visible="false"></asp:Label>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn HeaderText="Tipo">
<ItemTemplate>
<asp:Label ID="lblDescr" runat="server" Text='<%# Eval("Nombre") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtEditDescr" runat="server" Text='<%# Eval("Nombre") %>' Width="220px"></asp:TextBox>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn>
<ItemTemplate>
<telerik:RadButton ID="btnEditlist" runat="server" OnClick="btnEditlist_Click" Text="" RenderMode="Auto" CausesValidation="false">
<Icon PrimaryIconCssClass="rbEdit" />
</telerik:RadButton>
</ItemTemplate>
</telerik:GridTemplateColumn>
<%--<telerik:GridEditCommandColumn UniqueName="EditCommandColumn">
</telerik:GridEditCommandColumn>--%>
<telerik:GridButtonColumn Text="Delete" CommandName="Delete" />
</Columns>
</MasterTableView>
<ClientSettings EnableRowHoverStyle="true">
</ClientSettings>
</telerik:RadGrid>
and the button event
protected void btnEditlist_Click(object sender, EventArgs e)
{
GridItem reng = sender as RadButton.NamingContainer as GridItem;
GridDataItem Info = sender as RadButton.NamingContainer as GridDataItem;
string Id = reng.FindControl("lblID") as Label.Text;
}
But I can´t find the row values.

I advise that you first examine the following two sections of the documentation on getting data from a grid and on accessing controls in a template column:
- https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-raw-field-data-and-key-values
- https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-controls-in-template-column
Here's an example that applies that to the provided snippet where I highlighted the key changes:
protected void dg_NeedDataSource(object sender, GridNeedDataSourceEventArgs e){ (sender as RadGrid).DataSource = GetDummyData();}protected DataTable GetDummyData(){ DataTable tbl = new DataTable(); tbl.Columns.Add(new DataColumn("Idtip", typeof(decimal))); tbl.Columns.Add(new DataColumn("Nombre", typeof(string))); tbl.Columns.Add(new DataColumn("otherField", typeof(string))); tbl.Columns.Add(new DataColumn("FourthField", typeof(string))); tbl.Rows.Add(new object[] { 1, "one", 11, "red" }); tbl.Rows.Add(new object[] { 2, "two", 22, "green" }); tbl.Rows.Add(new object[] { 3, "three", 33, "blue" }); tbl.Rows.Add(new object[] { 4, "four", 44, "pink" }); return tbl;}protected void btnEditlist_Click(object sender, EventArgs e){ GridDataItem grdRow = (sender as Control).NamingContainer as GridDataItem; string data = grdRow.GetDataKeyValue("Idtip").ToString(); Response.Write(data);}<telerik:RadGrid ID="dg" runat="server" AllowSorting="true" Width="100%" RenderMode="Auto" PageSize="10" AutoGenerateColumns="false" AllowPaging="true" OnNeedDataSource="dg_NeedDataSource"> <PagerStyle Mode="NextPrevAndNumeric" Position="TopAndBottom" PageSizeControlType="RadComboBox" AlwaysVisible="true"></PagerStyle> <MasterTableView HierarchyDefaultExpanded="false" DataKeyNames="Idtip"> <CommandItemSettings AddNewRecordText="Nuevo" CancelChangesText="Cancelar" RefreshText="Actualizar" ShowRefreshButton="false" /> <Columns> <telerik:GridTemplateColumn HeaderText="Id" Visible="false"> <ItemTemplate> <asp:Label ID="lblID" runat="server" Text='<%# Eval("Idtip") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:Label ID="lblIDEd" runat="server" Text='<%# Eval("Idtip") %>' Visible="false"></asp:Label> </EditItemTemplate> </telerik:GridTemplateColumn> <telerik:GridTemplateColumn HeaderText="Tipo"> <ItemTemplate> <asp:Label ID="lblDescr" runat="server" Text='<%# Eval("Nombre") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtEditDescr" runat="server" Text='<%# Eval("Nombre") %>' Width="220px"></asp:TextBox> </EditItemTemplate> </telerik:GridTemplateColumn> <telerik:GridTemplateColumn> <ItemTemplate> <telerik:RadButton ID="btnEditlist" runat="server" OnClick="btnEditlist_Click" Text="" RenderMode="Auto" CausesValidation="false"> <Icon PrimaryIconCssClass="rbEdit" /> </telerik:RadButton> </ItemTemplate> </telerik:GridTemplateColumn> <%--<telerik:GridEditCommandColumn UniqueName="EditCommandColumn"> </telerik:GridEditCommandColumn>--%> <telerik:GridButtonColumn Text="Delete" CommandName="Delete" /> </Columns> </MasterTableView> <ClientSettings EnableRowHoverStyle="true"> </ClientSettings></telerik:RadGrid>Regards,
