customize GridHTMLEditorColumnEditor content

I'd like to customize the text displayed by the GridHTMLEditorColumnEditor ; I tried that but the content remains empty (the resourceValue column is bound only in the ItemDataBound event):

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

GridHTMLEditorColumnEditor editor = (GridHTMLEditorColumnEditor)editedItem.EditManager.GetColumnEditor("resourceValue");

editor.Editor.Content = "my custom text";

}

I think I've to return a Treenode-object not a TreenodeData-object. Have'nt I?

Best regards.

Grouping on a RadGrid making a gap in the header

When I group a RadGrid from the context menu, the headers all become slightly smaller than the data portion of the columns they are associated with. The result of this is that a white rectangle appears on the right hand side of the Header Bar. I have included the html for the grid below and included an attached file containing the image of the event happening.

I imagine this is something I can rectify by overriding the style for headers when the grouping is applied (Add a pixel or 2 to the RadGrid grouped header border style) but I would like to know if there is something that I should be doing that is more natural to the control itself

<telerik:RadGrid runat="server" ID="rgAMASM" DataSourceID="odsAMASM" AllowPaging="True"

GridLines="None" Skin="Office2007" AllowSorting="True" Height="347px" OnPageSizeChanged="rgAMASM_PageSizeChanged"

OnColumnCreated="rgAMASM_ColumnCreated">

<ClientSettings>

<Selecting AllowRowSelect="True" />

<Scrolling AllowScroll="True" UseStaticHeaders="True" />

</ClientSettings>

<MasterTableView DataSourceID="odsAMASM" CommandItemDisplay="Bottom" DataKeyNames="Asset_ID">

<CommandItemSettings ExportToPdfText="Export to Pdf"

ShowAddNewRecordButton="False" ShowRefreshButton="False">

</CommandItemSettings>

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False">

</FilterMenu>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

</telerik:RadGrid>

<asp:ObjectDataSource ID="odsAMASM" runat="server" SelectMethod="WT_BROWSEAMASM"

TypeName="WorkTech.WTLIB+WTDAL+Functions" OnSelecting="odsAMASM_Selecting" OnSelected="odsAMASM_Selected">

<SelectParameters>

<asp:Parameter Name="uid" Type="Int32" />

</SelectParameters>

</asp:ObjectDataSource>

RadGrid Header - Item misalignment on vertical scrollbar

Hi Telerik Team,

Before posting this issue, I tried search for similar issue here and tried. But couldn't solve our issue.

About our issue - (Which works fine in Firefox, but not working in IE8/9)
We are using Telerik RadGrid - which is displaying properly if there is NO vertical scrollbar. (Attachment - IE - With No Scrollbar.JPG)
If a vertical scroll-bar appears, the alignment between header and item goes wrong. (Attachment - IE.JPG)
This is displaying fine in Firefox - (Attachment - Firefox.JPG)

We noticed that if we resize the column width using mouse manually, entire alignment issue vanishes!! (Attachment - IE - Resizing.JPG & IE - After Resize.JPG)

I believe this explanation & screen-shots make sense.

This issue really kills the appearance of Telerik RadGrid and we are not satisfied with it - We tried a lot to fix it.

Finally we found that we are using on javascript to resize Grid's height & width based on the browser's width & height. That was causing this issue. When we commented the javascript code to set the grid's width, I think this issue is solved.

After posting the question for help only, we found this solution!!

Let us test this issue and will be back, if we have any issues.

Thanks
Steve
