Remove unnecessary code block as front end code is not at all required. What do you mean by calls two child grids? GridView is not something to be called. You also not specified what fired twice?

BlehBlahBah 16-Oct-13 2:54am

the entire gridview is getting fired twice. there are two inner grids inside the main gridview.

Thanks7872 16-Oct-13 2:55am

GridView is not something that gets fired. What do you mean by that? Explain me what you wanted to do and what is happening.

BlehBlahBah 16-Oct-13 5:19am

I basically want to bind the grid on event click. There are three grids which are bound. The first one which displays the header, then the second one which displays second header, and the third one which displays the details.

Now when I click, the major grid which contains the two other grid is displayed twice.

I want my grid to be called only once.

Solution 1

just remove the OnRowDataBound="grdGrpPrntRpt_RowDataBound" and rest from the front end. Your problem will be solved
