CommandItemSettings Show Update and Delete Buttons

[APESTANA]

Hi,
I was trying to use your CommandItemSettings to automatically display the Update and Delete buttons, like the AddNewRecordButton, but there is no such option available, I was wondering why? It would be useful to have those buttons available that would apply the command to the selected items in the grid, instead of having to add all to the CommandItemTemplate. These are common operations that one does in the grid...

Hi,

You can customize the CommandItemDisplay to your own(insert,update,delete buttons) using CommandItemtemplate as follows.
aspx:

<MasterTableView Width="100%" CommandItemDisplay="Top" DataSourceID="SqlDataSource1" DataKeyNames="CustomerID">
    <CommandItemTemplate>
       <div style="padding: 5px 5px;">
              Custom command item template
         <asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected" Visible='<%# RadGrid1.EditIndexes.Count == 0 %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Edit.gif" />Edit selected</asp:LinkButton>
       <asp:LinkButton ID="btnUpdateEdited" runat="server" CommandName="UpdateEdited" Visible='<%# RadGrid1.EditIndexes.Count > 0 %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Update.gif" />Update</asp:LinkButton>
      <asp:LinkButton ID="btnCancel" runat="server" CommandName="CancelAll" Visible='<%# RadGrid1.EditIndexes.Count > 0 ||         RadGrid1.MasterTableView.IsItemInserted %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Cancel.gif" />
Cancel editing</asp:LinkButton>
 <asp:LinkButton ID="LinkButton2" runat="server" CommandName="InitInsert" Visible='<%# !RadGrid1.MasterTableView.IsItemInserted                %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/AddRecord.gif" />Add new</asp:LinkButton>
     <asp:LinkButton ID="LinkButton3" runat="server" CommandName="PerformInsert" Visible='<%#                RadGrid1.MasterTableView.IsItemInserted %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Insert.gif" />                Add this Customer</asp:LinkButton>
   <asp:LinkButton ID="LinkButton1" OnClientClick="javascript:return confirm('Delete all selected customers?')"
runat="server" CommandName="DeleteSelected"><img style="border:0px;vertical-align:middle;" alt="" src="Images/Delete.gif" />Delete selected customers</asp:LinkButton>
            </div>
     </CommandItemTemplate>
</MasterTableView>

Also take a look into the following demo which explains the same scenario.
Grid / Command Item

Hi, 
I know that I can do it like that, but my question was why the CommandItemSettings does not have the ShowEditRecordButton and ShowDeleteRecordButton?

Regards, Ariel.

Hi Ariel,

The default buttons contained in the GridCommandItem are such that apply to the whole grid, the Delete and Edit buttons are shown per row and that is why they are not added in the command item. We cannot know whether the requirement would be to delete a selected row (and if selection would be enabled at all), or to have the row marked differently for edit or delete.

Hi,
i'm trying to implement a delete button in a RadGrid to do the following, after apply a filter I want to delete all records shown in the grid.
It's possible to do this? I haven't found a solution for this.

Hi,

Please try the following code snippet to delete the items after filter.

ASPX:

<CommandItemTemplate>
    <asp:Button ID="btnDelete" runat="server" Text="Delete" CommandName="Delete" />
</CommandItemTemplate>

C#:

static bool isFilter = false;
protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.FilterCommandName)
    {
        isFilter = true;
    }
    if (e.CommandName == "Delete" && isFilter == true)
    {
        foreach (GridDataItem items in RadGrid1.MasterTableView.Items)
        {
            string id = items.GetDataKeyValue("Id").ToString();
            //Code to delete
        }
    }
}

Thanks,
Princy

Hi,
thanks for the response, but this only gets my first 10 rows because i'm using paging.
I don´t know how to get all the results :/

Best regards,
JD

Hi,

You can cancel the Paging on delete command and set it again after deletion. Please try the following code snippet.

C#:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.FilterCommandName)
    {
        isFilter = true;
    }
    if (e.CommandName == "Delete" && isFilter == true)
    {
        RadGrid1.AllowPaging = false;
        RadGrid1.Rebind();
        foreach (GridDataItem items in RadGrid1.MasterTableView.Items)
        {
            string id = items.GetDataKeyValue("Id").ToString();
            //Code to delete
        }
        RadGrid1.AllowPaging = true;
        RadGrid1.Rebind();
    }
}

Thanks,
Princy

Hi,

thanks for the help Princy, i have just only one more issue I can´t solve. Instead of using the <CommandItemTemplate> I want to use a <asp:LinkButton>, but I can´t put this to fire the event RadGrid1_ItemCommand!

Thanks,
JD

[Princy]

Hi,

I guess you want to set asp:LinkButton instead of button in the CommandItemTemplate. Please make sure you have set the CommandName property for the LinkButton for the ItemCommand event to fire.

ASPX:

<CommandItemTemplate>
 <asp:LinkButton ID="lnkDelete" runat="server" CommandName="Delete"> Delete</asp:LinkButton>
</CommandItemTemplate>

Thanks,
Princy

[João]

No, what a want is a asp:Button or a asp:LinkButton to run the RadGrid1_ItemCommand method outside the CommandItemTemplate, is it possible?

Thanks,
JD

[Princy]

Hi,

I'm afraid this is not possible. If you want the button in the CommandItem area, you have to use the CommandItemTemplate.The ItemCommand event is raised when a button is clicked in the Telerik RadGrid control. This allows you to provide an event-handling method that performs a custom routine whenever this event occurs.
Hope this helps you. Please let me know if any concern.

Thanks,
Princy
