I have a StringCollection with size 100000. When using the following code to set each element to grid cell. It's very slow. (It spends about 10 seconds.)
Is there any way to speed up?


-- code snippet --

Dim arrayValues As New StringCollection

arrayValues = ... 'Get arrayValues

For col As Integer = 1 To arraySize.Count
GridControl1(1, col).Text = arrayValues(col - 1)

Hi Hanson,

Thank you for your interest in Syncfusion products.

The Grid can be loaded with the data of collection with high performance and less number of time when you load the data's virtually. The QueryCellInfo event can be used to apply data to each cell virtually.

Please refer the sample from our sample browser in the below location:

Let me know if you have any queries.
