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;
}
}
