Reorder and resizing of grid columns are occurring client side. When the user hides a column that has been reordered and a rebind occurs server side, although the columns are getting dynamically generated again, there is still a reference to the removed column in the grid and an exception is being thrown (see attached).

Have set the following during grid creation:
ViewStateMode = ViewStateMode.Disabled;
EnableViewState = false;

Have also tried doing a rebind in the client side methods which do the reorder and resize.  This seems to work on reorder (although performance may be an issue) but caused an exception for resize.

I need a way to clear the viewstate of the grid when the server side rebind occurs.  Setting the above settings did not work.

When entering data into a cell I can move to the cell on the right by pressing tab, (or the cell below by pressing enter.)

Ideally would like to be able to use the right arrow key to move to the cell on the right.

Is that possible?

Thanks

We are having an issue where chained classes are not being applied correctly. We have our custom css file added to the editor. So for example we type the word Button in the editor. In our css file there is a class called .button.ghost. I select the word Button and then select .button.ghost from the Apply CSS dropdown. However it will only apply ghost as the class. 

So it changes Button to 

<span class="ghost">Button</span>

Is there some setting or work around to have the classes applied in a way so the result of selecting .button.ghost would have the result of

<span class="button ghost">Button</span>

When pasting data into the Telerik Spreadsheet (using ctrl+v) I get the Page Unresponsive pop-up in Chrome and the Long Script running warning in Internet Explorer. This happens when pasting 3 columns of data (one string, two decimals) over 300 rows.

I have extended the number of rows using RowsCount="1000" in the telerik:RadSpreadsheet tag on the aspx page (.NET 4.0).

Any tips on:

1. Speeding up performance of the paste?

2. How to extend the time before Chrome shows the Page Unresponsive pop-up?  For up to 750 rows the paste will complete after 5 pop-ups are dismissed.

Thanks,

Rick

Hello,

When rendering a grid using Chrome for some reason the checkboxes are not visible (it's fine in firefox, ie 11, edge etc.) - though there are fairly significant differences between all of these usable.  The version of Chrome I'm using is 60.0.3112.90 (64-bit).  I'm not using any special styling or really any advanced techniques - pretty much stock standard grids.  Any help would be great.

Thanks

Okay I am sure this has been hammered in the forums, but searching has not pulled me back the desired help. We have a grid in a RadWizard. We do NOT want the grid to postback on switching the tabs in the wizard, coming to or going to a different tab. The data is loaded using the NeedDataSource method. I read where setting the EnableViewState=False, it should not hit the NeedDataSource again, after the initial load.

Regardless of ViewState being true/false, the method NeedDataSource is still being hit, wiping out the GridClientSelectColumn, because of the databinding. We tried setting the RadWizard property RenderedSteps="All" and "Active", but it did not matter. We need the grid to load once and never be loaded again, which is wiping out the checks. This grid is not update-able, editable, its just read only, with the option to check the GridClientSelectColumn.

How can we make this grid load once and never rebind itself again?

I have this code in my C# code behind page:

protected void gvEmailRedirectMaint_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;
            string ID = (editItem["ID"].Controls[0] as TextBox).Text;
            string RedirectEmailAddress = (editItem["RedirectEmailAddress"].Controls[0] as TextBox).Text;
            string ModifiedBy = userID;

            if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
            {
                GridEditableItem edititem = (GridEditableItem)e.Item;
                Regex regex = new Regex(@"^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$");

                TextBox txtbx = (TextBox)edititem["RedirectEmailAddress"].Controls[0];
                txtbx.Width = Unit.Pixel(300);

                Label l1 = new Label();
                l1.Width = Unit.Pixel(300);

                Match match = regex.Match(txtbx.Text);

                if (match.Success)
                {
                    l1.Text = "";
                }
                else
                {
                    l1.Text = "Please enter a valid email address";
                }
            }

When the user clicks the Update icon, I want to display a message if the email address is not in the proper format.  I want the error message to display directly to the right of the email address textbox.  But I can't get this to work.  Can anyone help?
