Hi,

I'm using arraylist for my wrapper grid to bind the child grids in order to export pdf but data is getting exported in  pdf file with two header items "Capacity" and "Count", not sure from where these are coming.

            ArrayList arrayList = new ArrayList();
            arrayList.Insert(0, Performance.GetPerformanceData1());
            arrayList.Insert(1, Performance.GetPerformanceData2());

            RadGridWrapper.DataSource = arrayList;
            RadGridWrapper.DataBind();

I strongly believe ArrayList is creating problem with radgrid, please check and let me know the solution for that as I need to use ArrayList.

Attaching the snap shot for your reference, please have a look.

Please disable the AutoGenerateColumns property on the RadGrid and manually set up the columns using either the designer, ASPX, or via the CodeBehind.

Issue still persist, please let me know if you have any other solution.

Hello Vivek,

You can hide the header item as shown in the following help topic:
PDF Export

P.S. I would recommend that you use advanced data-binding instead of simple data-binding approach. Regardless of the "advanced" word in the title, there is nothing complex here. Actually it is easier and more bulletproof approach.
