Hi,

I am getting one error ,that is

System.ArgumentOutOfRangeException was caught

  Message="Index was out of range. Must be non-negative and less than the

size of the collection. Parameter name: index"

while loading/assigning datasource to wingrid.Try...catch section is also not able to

catch this particular error.

I have gone through the site

http://devcenter.infragistics.com/Support/KnowledgeBaseArticle.Aspx?ArticleID=5165

but where  i need to write these methods?

I tried with this code but still error is coming after trying few

 times(50 times) ,It is no so frequent error.

                grdInvestor.BeginUpdate()
              grdInvestor.SuspendRowSynchronization()
                If grdInvestor.DataSource Is Nothing Then
                    grdInvestor.DataSource = DatabseReturnInvestor
                    grdInvestor.DisplayLayout.Bands(0).Columns("Investor").Width = 350
                    grdInvestor.DisplayLayout.Bands(0).Columns("Fund").Width = 350
                    HideExcelGridColumns(grdInvestor)
                End If
                grdInvestor.ResumeRowSynchronization()
                grdInvestor.EndUpdate()

I am also using some events like

grdInvestor_AfterRowUpdate,

grdInvestor_BeforeEnterEditMode

grdInvestor_DoubleClickRow

grdInvestor_InitializeLayout

grdInvestor_InitializeRow

grdInvestor_Click

I am attaching screen shots for reference.

Thanks in advance.

Regards,

Rajesh Kumar
