Solution: The data source does not support server-side data paging with GridView
Friends,
While working with GridView, I faced an issue while binding the data to GridView. The error message read as “The data source does not support server-side data paging.“. Initially I thought this was related to paging functionality of the GridView and looked into that, but thatw as not the solution. After doing bit of search, I found the reason of this error was the way a source is bound to the GridView. I will explain you here –
Initially this was my LoadData().
private void LoadData() { ProductInventory[] lines = GetData(); grdRows.DataSource = lines.Where(t => t.ProductID.StartsWith(tbSearch.Text)); grdRows.DataBind(); }
Here I am trying to get some data based on a filter using LINQ and applying it directly to the GridView. This was the main reason of the error. I just converted this resultset to a List using ToList() and voila, it works.The modified LoadData looks like below –
private void LoadData() { ProductInventory[] lines = GetData(); grdRows.DataSource = lines.Where(t => t.ProductID.StartsWith(tbSearch.Text)).ToList(); grdRows.DataBind(); }
In technical words from StackOverflow, “You can’t use an IQueryable object to data bind to a GridView and still use Paging and Sorting. You must return a List to the GridView using the ToList() method.”
Hope you like this! Keep learning and sharing! Cheers!
