I was wondering if there was a way to change the way the grid sort is handled? For example when the user clicks the header to sort and if one of the rows in the column is empty to not have it sort that row, but rather have anything with an empty row always come up last?

Binding to large data source

Hi,

I'm trying to create an interactive graph for a large data source.

When trying to bind the data source (list of Int) with about 50K data points, the application gets stuck on radChart1.DataBind();

What is the recommended way to display a graph (line chart) for such data?

Thanks,

Yoni

Chart (obsolete as of Q1 2013)

Grid group header height

Hello,

Problem with programmaticly setting the height of the group header (q3 2009).

Is the ViewCellFormatting event the place for adjusting the group header height?

Trying things like:
if (e.CellElement.RowInfo is GridViewGroupRowInfo)
{
      int height = Convert.ToInt32(Mo.LetterType.Height);
      if (height > 10)
      {
                e.CellElement.RowInfo.Height = height + 10;
      }
      else
      {
          e.CellElement.RowInfo.Height = 20
       }
}

Anybody got a suggestion?

Kind regards,

Tim van Rooijen

Changing elements' colors with Visual Style Builder

I want to say that you've done a great job and your controls look amazing. Now I'm trying to change one of the RibbonBar themes with your Visual Style Builder and I'm a little bit confused.
I have a hierarchy of Chunk - ElementWithCaptionLayoutPanel - FillPrimitive. If I want to change the BackColor of the chunk item which BackColor property I have to change? The BackColor of the Chunk, the BackColor of the ElementWithCaptionLayoutPanel or the BackColor of the FillPrimitive?

Dynamically calculate cell values

Dear everybody,

my request is it to dynamically calculate cell values.

I feed my RadGridView with a dataset or datareader. I am looking for an event which gets fired while data is bounded. The method shall allow me to modify the current cell value based on a calculation of other cells. Something similar like excel also provides with the formula stuff.

Is there any way you can help me?

I also tried events like cellvaluechanged, cellvalidation,valuechanging and the other stuff.

Thanks for a quick reply.

best,

GridView
