This doesn't seem like it should be that difficult but I can't figure out how to do it. I have a grid with an ImageButton template column. When the ImageButton is clicked, I want to access the grid and retrieve certain column key values from that row on the client side. The row is not selected, so the grid.get_masterTableView().get_selectedItems()[0] does not work. How can I do this?

Thanks,
Jeff G.

[Solved] Auto select new row after adding

Hi, does anyone know how to automatically select a new row immediately after adding it? I would like my users to be able to add a new row and then it is selected (highlighted) automatically (wouldn't want to tire their fingers out ...joke).

Thanks.

401 from Telerik.Web.UI.WebResource.axd

Just FYI, I was getting a 401 from my Captcha control (using SharePoint + IIS6) when it accesses the Telerik.Web.UI.WebResource.axd handler. This is because my SharePoint site is not anonymous at the top level, but only at specific sub-site levels.

Adding this to the Web.config file seemed to work:

<location path="Telerik.Web.UI.WebResource.axd">
    <system.web>
      <authorization>
        <allow users="*"/>
      </authorization>
    </system.web>
</location>

[Solved] Unable to cast object of type 'ASP.masterpage_master' to type 'Telerik.Web.UI.GridTableView'.

Using 3.5 controls - Have Telerik project set to use the 3.5 binary inside my solution structure.

I have a web page with a gridview control with paging enabled. The data is coming from a sql datasource (I also tried changing it to use a List<> with the OnNeedDataSource event.

I can view the grid fine and page back and forth between the numeric pages however when I change the PageSize drop down I get this error message.

Unable to cast object of type 'ASP.masterpage_master' to type 'Telerik.Web.UI.GridTableView'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidCastException: Unable to cast object of type 'ASP.masterpage_master' to type 'Telerik.Web.UI.GridTableView'.

Source Error:


            An unhandled exception was generated during the execution of the
            current web request. Information regarding the origin and location of
            the exception can be identified using the exception stack trace below.

Stack Trace:

[InvalidCastException: Unable to cast object of type 'ASP.masterpage_master' to type 'Telerik.Web.UI.GridTableView'.]
   Telerik.Web.UI.RadGrid.RaisePostBackEvent(String eventArgument) +1719

   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

I put the Telerik.Web.UI.DLL into reflector and inspected the raisepostbackevent method for the radgrid I'm only seeing 2 places where it directly casts it to a GridTableView

    
                if (eventArgument.IndexOf("FireCommand") != -1) 
        
                { 
        
                    GridGroupByExpression expression2; 
        
                    GridGroupByExpression expression3; 
        
                    string id = eventArgument.Split(new char[] { ';' })[0].Split(new char[] { ':' })[1]; 
        
                    GridTableView tableView = (GridTableView) this.Page.FindControl(id); 
        
             ...
        
                if (eventArgument.IndexOf("ReorderColumns") != -1) 
        
                { 
        
                    GridTableView view = (GridTableView) this.Page.FindControl(eventArgument.Split(new char[] { ',' })[1]);

Is there any chance that eventArgument.Split is returning something like "this" that it would pick up the masterpage reference somehow?

Or does anyone have any idea what could be causing this error?

Mimic double click functionality in Context Menu

I have a context menu that has an "edit" item. I would like to have that "edit" item perform as the double click functionality does. What it does not seem to do is handle recurring events properly -- it does not popup the box that asks whether to edit a single occurrence or the whole series.

EDIT: Disregard. I had code that was breaking this functionality. It is now working.

Arrow indicating children for submenu

Hello all,

I'm using the horizontal menu with drop downs.
I've successfully deployed a custom CSS for my menu, however I can not figure out how to display the arrow effect when an item has children.
I've found the css skin file selectors, and it looks like rmExpandLeft is the class to manipulate it, but when I add that element to the CSS file it doesn't do anything.
I've compared the source for "Default" css and my custom css and the HTML output is the same; additionally, there is NO rmExpandLeft in the HTML, so I'm not sure how to determine if it has children.

Any clues?

Regards

Matt

[Solved] Access Edit Item in SqlDataSource Updating Event

I need to access the item that is being edited from the updating event of a SqlDataSource. Currently, I am able to access the item by using the following code.

protected void SqlDataSource1_Updating(object sender, SqlDataSourceCommandEventArgs e)

{

foreach (GridItem item in rgvResult.MasterTableView.Items)

{

if (item.Edit)

{

GridEditFormItem editItem = (GridEditFormItem)rgvResult.MasterTableView.GetItems(GridItemType.EditFormItem)[item.ItemIndex];

//do stuff

}

Is there a method similar to GetInsertItem() that I can use to get the edited item or do I have to loop through the collection to get the item?
