RadGrid Cell Formatting in ASP.NET

Hi,
I've set the data source of the RadGrid dynamically. Now I'm trying to set the cell formatting of the RadGrid because in my case i've to set different formatting (bold, italic, underline etc) of the each grid cell. For example, i want to set the font bold to true for the only first row and first column which will be basically first cell of the grid. i.e.

I've tried to do using the following code but in vain. One more thing, i'm not able to see the cell value at this point. I've tried both the ItemCreated and ItemDataBoudn event but nothing is working for me.

protected

void RadGridComparableAnalysis_ItemDataBound(object sender, GridItemEventArgs e) {

if (e.Item is GridDataItem) {

e.Item.Cells[0].Font.Bold =

true;
}
}

DesignMode display issue with Splitter

Hi,

I set up a simple example of the issue I'm seeing, using one of the free demos online. The mark-up for the splitter looks like this.

<telerik:RadSplitter id="RadSplitter1" runat="server" height="200" width="500">
                <telerik:RadPane id="RadPane1" runat="server">Left Pane -
                    set to <b>free</b> size </telerik:RadPane>
                <telerik:RadSplitBar id="RadSplitbar1" runat="server"></telerik:RadSplitBar>
                <telerik:RadPane id="RadPane2" runat="server">Middle Pane - set to <b>free</b> size </telerik:RadPane>
                <telerik:RadSplitBar id="RadSplitbar2" runat="server"></telerik:RadSplitBar>
                <telerik:RadPane id="Radpane3" runat="server">End Pane - set to <b>free</b> size
                </telerik:RadPane>
            </telerik:RadSplitter>

While in run-time the splitter control and all panes display correctly, but in DesignMode the panes are displayed on top of each other, instead of side by side.

Is there any way to correct the look of the panes in DesignMode?

Thanks in advance,
Tom

Radgrid with export to pdf

Hi,
I have one rad grid with export to pdf functionality. I have put one html table in item command template which contains, image, report name, generated datetime etc. I add this table which looks like report header. But when I click on export to pdf link in command item template, it does not export command item template data. If I remove table and write text direct into command item template than it works fine and I can see text from command item template to pdf. But I can't format header data without table so I can't remove table from command item template. Export to excel and word works fine.

Can any one help me in this? Columns in below grid are generating at run time.

An item with the same key has already been added.

I have a RadGrid in a FormView. I bind to the FormView with an object datasource. The grid binds to a List that is a property of the object datasource object. The first time loading the page (in Edit Mode) which retrieves a record everything works fine and the grid binds to the List. When I hit Submit to save everything I get the error. We are running 2010.1.415.35
