Problem with GridButtonColumn and RadAlert in Grid

[Pandu]

Dear Telerik Team,

I have a page with RadGrid control which has some bound columns and GridButton column which is for delete (having inner) item in grid. Open a popup when click on command item link button and it has a tabstrip which has three tabs. In third tab we have a grid which has to ask radconfirm on OnClient event when click on Generate command item Link button. If OK it has to fire event and do some operation. I tried with all the ways from the articles,forum and documentation source but i didn't. At last i tried with the below script which is working fine but i am unable to fire Delete in Grid.

<script language="javascript" type="text/javascript">
        var oldConfirm = radconfirm;
        window.radconfirm = function(text, mozEvent, oWidth, oHeight, callerObj, oTitle)
        {
            var ev = mozEvent ? mozEvent : window.event; //Moz support requires passing the event argument manually
            //Cancel the event
            ev.cancelBubble = true;
            ev.returnValue = false;
            if (ev.stopPropagation) ev.stopPropagation();
            if (ev.preventDefault) ev.preventDefault();

            //Determine who is the caller
            var callerObj = ev.srcElement ? ev.srcElement : ev.target;

            //Call the original radconfirm and pass it all necessary parameters
            if (callerObj)
            {
                //Show the confirm, then when it is closing, if returned value was true, automatically call the caller's click method again.
                var callBackFn = function (arg)
                {
                    if (arg)
                    {
                        callerObj["onclick"] = "";
                        if (callerObj.click) callerObj.click(); //Works fine every time in IE, but does not work for links in Moz
                        else if (callerObj.tagName == "A") //We assume it is a link button!
                        {
                            try
                            {
                                eval(callerObj.href)
                            }
                            catch(e){}
                        }
                    }
                }

                oldConfirm(text, callBackFn, oWidth, oHeight, callerObj, oTitle);
            }
            return false;
        }
    </script>

Can you please go through this issue and give me a better solution.

Hello Pandu,

You could try firing a custom RadGrid's command from the client with the following code snippet:
JavaScript

var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
masterTable.fireCommand("MyCustomCommand", RadGridItemID);

Then on RadGrid.ItemCommand event handler you could check if the fired command is the custom command and perform delete operation:

void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    if (e.CommandName == "MyCustomCommand")
    {
         int itemID = Convert.ToInt32(e.CommandArgument.ToString());
         // Delete item with ID equals to value in itemID.
         ...
    }
}

I hope this helps.

Kind regards,

Hi,
I'm using a external Linkbutton (in a user control) to delete a selectedrow in a RadGrid, It works fine.
I add onCLientClick a call to a javascript function to show a RadConfirm message before execute the delete command.. but i never get show the radconfirm... seems that it doesn't work whith the  item.FireCommandEvent . Is this possible ?
I'd like to keep the radconfim in a javascript function not inside codebehind.

code:

Button:

<asp:ImageButton ID="imbDelete" runat="server" AlternateText="Elimina" CausesValidation="False" Enabled="false"

                    ImageUrl="~/Images/delete.png" CssClass="pulsante_disabled"  OnClick="imbDelete_Click" OnClientClick="return ConfirmationDelete(this);"  /> 

  

Code behind:

foreach (GridDataItem item in _rdgPopup.MasterTableView.GetSelectedItems())

                        item.FireCommandEvent("DeleteSelected", String.Empty); 

  

javascript code ( external file )

  

  

 function ConfirmationDelete(clickedButton)

  {

      alert('confirm');

     function confirmHandler(args)

      {

          if (args == true)

          {

              __doPostBack(clickedButton.name, '');            

         }

     }

  

     radconfirm(vQuestionText, confirmHandler, 250, 100, null, vTitle);

     return false;

 }

Thanks!!

Hello,

 I checked your code and it was working correctly on my end. You can see it in the attached sample page. You should check whether you have RadWindowManager on the page if it is configured properly.
