I'm attempting to get my RadGrid to show the NestedTemplate when the row is clicked, but show the edit template when the Edit button (created via a GridEditCommandColumn) is clicked.

In my ItemCommand handler, I have the following code:

    
            if(e.Item is GridDataItem)  
        
            {  
        
              if(e.CommandName == "RowClick")  
        
              {  
        
                  if(e.Item.Selected)  
        
                  {  
        
                      e.Item.Selected = false;  
        
                      e.Item.Expanded = false;  
        
                  }  
        
                  else 
        
                  {  
        
                      e.Item.Selected = true;  
        
                      e.Item.Expanded = true;  
        
                  }  
        
                  e.Item.Edit = false;  
        
              }  
        
              else if(e.CommandName == "Edit")  
        
              {  
        
                  e.Item.Selected = true;  
        
                  e.Item.Expanded = false;  
        
                  e.Item.Edit = true;  
        
                  myGrid.Rebind();  
        
              }  
        
            }

This code works fine for selecting the row via a RowClick, but the ItemCommand fires twice for the Edit button click, once with a CommandName of Edit, and then once with a CommandName of RowClick. This results in the row showing the NestedTemplate instead of the EditTemplate.

Futhermore, it appears that the state from the first ItemCommand event does not exist for the second ItemCommand event. In other words, the fact that I set the row to Selected and Expanded does not show up when the second ItemCommand event is handled, so I can't check this information and prevent the RowClick from messing things up.

What am I doing wrong?

Hi,

A suggestion would be to use a global variable which you could set in the edit command and check the same in the ROwClick.You can then cancel the Expand in the condition as shown below:

    
            public static int flag = 0; 
        
            protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e) 
        
                    { 
        
                        if (e.CommandName == "RowClick") 
        
                        { 
        
                            if (flag == 1) 
        
                            { 
        
                                e.Item.Selected = true; 
        
                                e.Item.Expanded = false; 
        
                                e.Item.Edit = true; 
        
                                RadGrid1.Rebind(); 
        
                            } 
        
                        } 
        
                        else if (e.CommandName == "Edit") 
        
                        { 
        
                            flag = 1; 
        
                        }   
        
                    }

Hi Tsvetoslav,

Thanks for looking. In the mean time i have got it working the way i want. Instead of firing the postback by setting the Clientsettings

"EnablePostBackOnRowClick

= true" i am now calling the RaisePostBack event using javascript.

To give you more details i am doing as follows:

JS:

    
            <script type="text/javascript">  
        
                function RowClick(index) {  
        
                    __doPostBack("<%= this.UniqueID %>", "RowClick");  
        
                }  
        
                </script>

ASPX:

    
                    <ClientSettings EnableRowHoverStyle="true">  
        
                        <Resizing AllowColumnResize="true" /> 
        
                        <Scrolling AllowScroll="True" UseStaticHeaders="True" /> 
        
                        <ClientEvents OnRowClick="RowClick"></ClientEvents> 
        
                        <Selecting AllowRowSelect="True" /> 
        
                    </ClientSettings>

CS:

    
            void IPostBackEventHandler.RaisePostBackEvent(string eventArgument)     
        
                    {     
        
                        switch (eventArgument)     
        
                        {     
        
                            case "RowClick":     
        
                                //Code goes here     
        
                                break;     
        
                        }     
        
                     }

But now i have another issue. I have lost the ajaxification when i do this. So as soon as i click on the row it does a normal postback instead of ajaxifying the page. To give you more details

I am using a Master Content Form. The aspx page has a usercontrol with the grid on it. So all of the above code shown is in usercontrol. Now we have the RadAjaxLoadingPanel on the master page & the RadAjaxPanel on the aspx pages. This works well for everything as in it ajaxifies all the controls but doesnt work when i click on the grid row in the usercontrol.

Please let me know how can i overcome this.

Thanks & Regards

Hi Admin,

I am facing the similar problem but without nested views.

I have a single MasterTableView and in that I have a TemplateColumn with a RadCombo and a command button in it, I have given the CommandName for that button as "Assigned", I am handling the event in ItemCommand event of RadGrid, its working fine. But also I am using built-in "RowClick" command name to redirect the user, if they click anywhere else other than TemplateColumn.

Now, if I click on TemplateColumn, then it does the operation of "Assigned" and then it repeats the ItemCommand procedure and this time "RowClick" operation is performed, which I don't want.

Any help please?

Regards.
