Hi,

I am using "Edit UI elements" to style a RadGrid.
As soon as i change anything to do with Header part it breaks my application.

Error details
--------------------------
Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index

On following lines (pageName.Designer.cs) (As soon as i remove these lines, my code works fine.)
-----------------------------------------------------------------------------------------------------------------------------------
((Telerik.WinControls.UI.GridGroupHeaderItem)(this.radGridClinics.GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0))).BackColor2 = System.Drawing.Color.FromArgb(((int)(((byte)(49)))), ((int)(((byte)(168)))), ((int)(((byte)(101)))));
            ((Telerik.WinControls.UI.GridGroupHeaderItem)(this.radGridClinics.GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0))).HorizontalLineWidth = 0;
            ((Telerik.WinControls.UI.GridGroupHeaderItem)(this.radGridClinics.GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0))).BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(240)))), ((int)(((byte)(247)))), ((int)(((byte)(240)))));
            ((Telerik.WinControls.UI.GridGroupHeaderItem)(this.radGridClinics.GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(1).GetChildAt(0))).BackColor2 = System.Drawing.Color.FromArgb(((int)(((byte)(49)))), ((int)(((byte)(168)))), ((int)(((byte)(101)))));
            ((Telerik.WinControls.UI.GridGroupHeaderItem)(this.radGridClinics.GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(0).GetChildAt(1).GetChildAt(0))).BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(240)))), ((int)(((byte)(247)))), ((int)(((byte)(240)))));

Problem with "Enter" in Multiline GridViewTextBoxColumn

Hi!

Im trying to use an alternative GridEditor to input Enter into an Textfield in an RadGridView and found the example above anywhere here in the forum.

The problem is, when I'm clicking in the Editbox to edit the text everything works fine, but when I click on the same or on an other textfield in the grid no cursor is shown and it's not possible to edit the fields as long as i reopen the form.

Please help

regards

Willi

                        Private Sub grdOPdaten2_EditorRequired(ByVal sender As Object, ByVal e As EditorRequiredEventArgs) Handles grdOPdaten2.EditorRequired         
                    If e.EditorType Is GetType(RadTextBoxEditor) Then         
                        e.EditorType = GetType(MyTextBoxEditor)         
                    End If         
                End Sub

Designer looses settings

Hi,

I added a tab strip with two tab items on the left side. Furthermore I changed the TextOriantation to vertical so that the text appears horizontal on screen. At the end I attached an Image to both tab items. After compiling the application the height of the tab strip changes, both tab items looses their ImagePrimitive settings and the second tab item looses the attached image.

Regards

Martin

Multiple ConditionalFormattingObjects problem

Hello,

I'm trying to use conditional formatting based on two different columns in a grid.

One is a bool column, based on it i change the row forecolor, the other one is an int and based on it i change the row backcolor. Both are applied to the full row. If i only create the first formatting, it works fine. If i add the second formatting object, the first one does not work anymore. I am only setting RowForeColor on the first formatting object and RowBackColor on the second one. What am i doing wrong? Or are the conditionalFormattingObjects built such that you can only use them on one column at a time on a grid if you apply them to the full row.

Waiting for your response
