hi,

RadGrid will automatically show formtemplate content (such as label below: TEMPLATE APPEAR HERE) if I click on standard commandname 'InitInsert' or 'EditSelected' link:

... 
<FormTemplate> 
    <asp:Label ID="Label1" runat="server" Text="TEMPLATE APPEAR HERE"></asp:Label> 
</FormTemplate> 
 
... 
<CommandItemTemplate> 
    <div align="left"
      <asp:LinkButton ID="initInsertLinkButton" runat="server" CommandName="InitInsert">Add new 
      </asp:LinkButton> 
      <asp:LinkButton ID="editSelectedLinkButton" runat="server" CommandName="EditSelected">Edit Selected 
      </asp:LinkButton> 
       <asp:LinkButton ID="copyLinkButton" runat="server" CommandName="CopyCommand"></asp:LinkButton> 
    </div> 
</CommandItemTemplate> 

Now, I introduce a custom commandName 'CopyCommand' to do the same to open formtemplate content.

It looks very simple but I just can't get it to work. Anyone knows a way to do this?

Thanks

Elvin

Hi Elvin,

Attach the ItemCommand and execute the following code snippet in order to simulate the EditSelected button behaviour.

C#:
 
protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e) 
    { 
        if (e.CommandName == "CopyCommand"
        { 
            RadGrid1.SelectedItems[0].Edit = true
            RadGrid1.MasterTableView.Rebind(); 
        } 
    }

Thanks for hinting, Shinu.

From your code, as I don't want to force bind by a selected item (without which will throw a null exception), I modify to below:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)  
{  
    if (e.CommandName == "CopyCommand")  
    {  
        e.Canceled = true;  
        e.Item.OwnerTableView.InsertItem();  
 
        GridEditableItem insertedItem = e.Item.OwnerTableView.GetInsertItem();  
        HtmlTable formTable = insertedItem.FindControl("formTable") as HtmlTable;  
        HtmlTable copyTable = insertedItem.FindControl("copyTable") as HtmlTable;  
      
        formTable.visible = false;  
        copyTable.visible = true;  
    }  

Again, the form template content doesn't open..?

Hello Elvin,

Attached to this message, is a small application, which handles a similar setup, and the insert form is properly shown. I hope it gets you started properly.

I almost want exactly the same behavior...
First I have a GridClientSelectColumn in my grid.  I want to be able to select one or more records using the

 

GridClientSelectColumn and fire the EditSelected command to open formtemplate that I have set it's EditMode='PopUp'.  When my formtemplate displays only the last row is still selected in the grid.  I want to have to user enter more data in the formtemplate and save that info for all the selected rows...   

This is what I've tried to keep rows selected. nothing has worked so far

protected void Radgrid1_ItemCommand(object source, GridCommandEventArgs e)
       {
           if (e.CommandName == RadGrid.EditSelectedCommandName)
           {                
               foreach (GridItem gi in Radgrid1.SelectedItems)
               {                
                   Radgrid1.SelectedItems[0].Edit = true;                     
               }
               Radgrid1.MasterTableView.Rebind();
           }  
       }

It seems like this should be easier.  I also tried to set AllowMultiRowEdit="True" in the grid but it fires a popup for every selected row.

Thanks for any help.

 Hello,

I guess your requirement is, you want to edit all the selected rows using a single pop up editform. For that the first step would be checking for 'SelectCommandName' in ItemCommand event and saving the DataKeyValue of all selected rows in an array. And then when updating loop through each of this items (using the datakeyvalue array) and prepare the update query for to update the db. Now rebind the grid to show the updated values.

Hope this information helps,
Princy.
