Can I do that ??

[Smiely]

I have RadWindow poping up from RadGrid column click. I am always reloading the grid when RadWindow is closed to reflect the changes. If nothing has changed, I am wasting time and resources for reloading grid. How can I check if something has done in RadWindow? can I do that ?

Please help.... need experts guidence on this ...

Hello Smiely,

Thank you for contacting us.

In this case you can make use of the RadScriptManager response scripts or if you are using some rad ajax panel or ajax manager you can use their ResponseScripts function.
Say, in case you have updated the data source then you inject a script that tells the RadWindow to call the function and rebinds the grid, otherwise call just the function that closes the window.

Another solution would be to pass an argument through the script manager, then that argument will be available in the method that initiates the ajax request and decide whether the ajax request should be fired or not.

Hope this helps.

Kind regards,

Hi Smiely,

You can do the following:
In the window page make sure you have implemented:

function CloseWindowAndRebind(needToRebind) {
    GetRadWindow().BrowserWindow.refreshGrid(needToRebind);
    GetRadWindow().close(needToRebind);
}
    function GetRadWindow() {
        var oWindow = null;
        if (window.radWindow)
            oWindow = window.radWindow;
        else if (window.frameElement.radWindow)
            oWindow = window.frameElement.radWindow;
        return oWindow;
    }

Then in the code behind you would have:

string functionName= string.Format("CloseWindowAndRebind({0})", "yes");
ClientScript.RegisterStartupScript(Page.GetType(), "someId", functionName, true);

And on the other page (that has the grid):

function refreshWindow(needToRefresh) {
    if(needToRefresh=="yes")
        //do something
}

Hope this helps.
