Disable a asp.net button

[Yamil]

Hi. I would like to enable/disable a button when a select a row in a RadGrid.
In my ItemCommand event I do:
button.Enabled = true

but when the button keeps disable. I am also add a RadAjaxManager and I declared a source control, the grid and target control, the button but it does not work...?

Is there something I left out ?

Hi,

Try the following code snippet to enable  a button on selecting a particular row.

ASPX:

 <telerik:RadGrid ID="RadGrid1"   runat="server"  DataSourceID="SqlDataSource1" OnItemCommand="RadGrid1_ItemCommand" >

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

                    <Columns>
                      <telerik:GridButtonColumn UniqueName="SelectCol" ButtonType="LinkButton" Text="Select" HeaderText="Select" CommandName="Select"   ></telerik:GridButtonColumn>
                        <telerik:GridTemplateColumn UniqueName="ButtonCol" HeaderText="ButtonCol"  >
                          <ItemTemplate>
                              <asp:Button ID="Button1" runat="server"  Enabled="false" Text="Button" />
                          </ItemTemplate>
                        </telerik:GridTemplateColumn>
                    </Columns>
                </MasterTableView>
            </telerik:RadGrid>

CS:

 protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "Select")
        {
            GridDataItem item = (GridDataItem)e.Item;
            Button btn = (Button)item["ButtonCol"].FindControl("Button1");
            btn.Enabled = true;
        }
    }

Thanks
Shinu.

Hi Yamil,

Try the following code snippet to achieve the desired scenario.

CS:

 protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "Select")
        {
            Button1.Enabled =true;
        }
    }

ASPX:

 <telerik:RadGrid ID="RadGrid1"   OnItemCommand="RadGrid1_ItemCommand" OnPreRender="RadGrid1_PreRender" >

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

                </ClientSettings>
                <MasterTableView  DataSourceID="SqlDataSource1">

                    <Columns>



                       <telerik:GridButtonColumn UniqueName="Select"  Text="Enable" CommandName="Select" ></telerik:GridButtonColumn>

                    </Columns>

                </MasterTableView>
            </telerik:RadGrid>
            <asp:Button ID="Button1" runat="server" Enabled="false" Text="Button" />

Hope this helps..
Shinu.

Hi Yamil,

If you need to ajaxify the entire scenario you can wrap the RadGrid and the Button inside a RadAjaxPanel and the use the above given code.
