Unable to set Text-Property for columns with index greater than 10 (virtual grid)


i have a little problem with your grid control.
I found this thread (http://www.syncfusion.com/forums/88374/how-to-set-gridcontrol-column-header) and in the last rows you wirte the following snippet:

GridB[0,1].Text="Header1"; // Set the Header text for First header cell

So i tried this solution and after 5 hours i'm getting headache...
I cannot set the text/value of a header column, if it's index is greater than 10!
I have simplified my test code for you. Please check the comments.

private void SetupHeaderTest()
            gridControl1[0, 3].Text = "Jul";

            //works anyways..
            var blu = gridControl1[0, 8];
            gridControl1[0, 8].Text = "Aug";
            var blu2 = gridControl1[0, 8];

            if (blu.Equals(gridControl1[0, 8]))
                //they are not equals

            if (blu.Equals(blu2))
                //they are not equals

            var test2 = "Sep";
            var bla = gridControl1[0, 10];
            bla.Text = test2;

            //gridControl1[0, 10] = bla; //works!

            //DO NOT work!
            var test3 = "Sep";
            var bla3 = gridControl1[0, 11]; // if column greater then 10, it do not work!
            bla3.Text = test3;

            //gridControl1[0, 11] = bla3; -->arrayOutOfBounds

Can anyone help me out?

best regards

Hi Marcel,

Thank you for your interest in Syncfusion products.

We have analyzed your reported scenario. We would like to let you know that by default virtual grid will contain 5 rows and 10 columns bind initially. Only those cells can be accessed by you initially. If you want to access beyond that you need to use QueryCellInfo event. Using events to access is the appropriate way, else the purpose of using Virtual Grid would be waste. Please refer the below code, sample and KB for clarification.

Code Snippet[c#]:          

void GridQueryCellInfo(object sender, GridQueryCellInfoEventArgs e)


     //Correct usage. Cell values should be accessed only in events for virtual grid.

      if (e.RowIndex == 0 && e.ColIndex == 11)


           var test3 = "Sep";

           var bla3 = e.Style;

           bla3.Text = test3;

           e.Style.Text = bla3.Text;





Sample :

Please let us know if you have any other concerns.
