# Context
- Using RadGridView
- Having a column named "MyDataColumn", which contains different decimal values, including zero.
- Using UI, add filter on "MyDataColumn" : "Greater than: 0"
- Added a calculated column named "MyCalculatedColumn", using expression "MyDataColumn / MyDataColumn".
- Note that, at this point, it doesn't crash since we added the "Greater than: 0" filter on "MyDataColumn" ... without that filter, it will crash, as we all know division by zero is impossible.

# Behavior
- Using UI, add a filter on "MyCalculatedColumn"
- Application crash

On my grid I am grouping by one field, and have gridview1.mastertemplate.ShowTotals = True so that I can show a grand total for columns when that grid is grouped.  My issue is that I need to change the appearance of the grand total row differently than the other (group) summary rows in ViewCellFormatting.  Is this possible, and if so how can I do it?

 

Thanks

William

When in the edit mode, GridSpinEditor inside RadGridView allows the numeric value to change by scrolling mouse centerl scroll wheel. I need to disable this. How can I disable this feature?

This feature lets the users to scrolldown to negative values, which is not desirable.

Thanks.

Hello

What is the best way to adapt the text of the default context menu of a treeview ? I know that I could change the text property of each item on the ContextMenuOpnening but a more global solution as a Localization Provider will be welcome.

Thanks for your support

Hi,

I need to customize the filter popup to add some new choices.

I've tried to add item this way :

        private void radGrid_FilterPopupRequired(object sender, FilterPopupRequiredEventArgs e)
        {
            var popUp = e.FilterPopup as RadListFilterPopup;
            if (popUp == null)
                return;

            var rmiSortByColor = new RadMenuItem("Sort by color");
            popUp.Items.Insert(0, rmiSortByColor);​

            [...]

  

Unfortunally, as you can see in the provided screenshot, the item is very huge, and the height increase proportionally when I resize the popup.

I have the exact same problem when I add a simple separator.

 

Did I miss something ?

My problem is occured at RadScheduler control on Timeline View mode about scrolling.

Follow my attach image, when I click at number 1 view'll change 1 scale (Ex. 1 hour).

If I click at number 2 I'll got same result with number 1.

My question is how I change scroll range at number 2 (Ex. view move forward to 4 hour per click)

 

Thank you.

Hi, I have a RadButton to which i set the next properties at runtime:

    RadButton btn = ((RadButton)radPanelButtons.Controls[radPanelButtons.Controls.Count - 1]);
            btn.Dock = DockStyle.Left;
            btn.Text = text;
            btn.TextImageRelation = TextImageRelation.ImageBeforeText;
            btn.Image = img;
            var imagePrimitive = ((ImagePrimitive)btn.ButtonElement.ImagePrimitive);
            ((TextPrimitive)btn.ButtonElement.Children[1].Children[1]).TextWrap = true; 
            btn.TextAlignment = ContentAlignment.TopLeft;
            btn.TextAlignment = System.Drawing.ContentAlignment.MiddleLeft;​

 The text moves next to the image, but the button size remains the same. See the picture.
