Hi,

     My real issue was ,I am having a grid with one column as image.

The image column  is created using a column value like this

Protected Sub DataGrid1_InitializeRow(sender As Object, e As Infragistics.WebUI.UltraWebGrid.RowEventArgs) Handles DataGrid1.InitializeRow
            If (e.Data("IsStandardIcon") = "1") Then
               e.Row.Cells(3).Text = "<center><img src='../Images/StandardS.png'></center>"
               e.Row.Cells(3).Value = "1"
            Else
                e.Row.Cells(3).Text = ""

            End If

END SUB.

          When you are trying to change the text of the cell,its value also will change.,so the sorting of the column will not work.

Now I have modified the code as follows

Dim colIsStandardIcon As New UltraGridColumn("IsStandardIcon", "<center><img src='../Images/StandardS.png'></center>", ColumnType.CheckBox, Nothing)
                colIsStandardIcon.BaseColumnName = "IsStandardIcon"
                colIsStandardIcon.Width = Unit.Pixel(25)
                colIsStandardIcon.AllowUpdate = AllowUpdate.No
             Me.DataGrid1.DisplayLayout.Bands(0).Columns.Add(colIsStandardIcon)

             Dim dtStandardExist As New DataTable
                dtStandardExist.Columns.Add("DisplayText")
                dtStandardExist.Columns.Add("Value")
                Dim drStandardExist As DataRow = dtStandardExist.NewRow

                drStandardExist("DisplayText") = "<center><img src='../Images/StandardS.png'></center>"
                drStandardExist("Value") = "1"
                dtStandardExist.Rows.Add(drStandardExist)

                Dim drStandardNotExist As DataRow = dtStandardExist.NewRow
                drStandardNotExist("DisplayText") = "."

                drStandardNotExist("Value") = "0"
                dtStandardExist.Rows.Add(drStandardNotExist)

                For Each dr As DataRow In ds.Tables("Knowledge").Rows
                    'If (dr("IsStandardIcon").ToString() = "0") Then
                    '    Me.DataGrid1.DisplayLayout.Bands(0).Columns.FromKey("IsStandardIcon").ValueList.DataSource = dtStandardExist
                    'End If
                    'ElseIf (dr("IsStandardIcon").ToString() = "0") Then
                    'Me.DataGrid1.DisplayLayout.Bands(0).Columns.FromKey("IsStandardIcon").ValueList.DataSource = dtStandardExist

                    Me.DataGrid1.DisplayLayout.Bands(0).Columns.FromKey("IsStandardIcon").ValueList.DisplayMember = "DisplayText"
                    Me.DataGrid1.DisplayLayout.Bands(0).Columns.FromKey("IsStandardIcon").ValueList.ValueMember = "Value"
                    Me.DataGrid1.DisplayLayout.Bands(0).Columns.FromKey("IsStandardIcon").ValueList.DataSourceID = "Value"
                    Me.DataGrid1.DisplayLayout.Bands(0).Columns.FromKey("IsStandardIcon").ValueList.DataBind()
                    Me.DataGrid1.Columns.FromKey("IsStandardIcon").Type = ColumnType.DropDownList
                    Me.DataGrid1.DisplayLayout.AllowUpdateDefault = AllowUpdate.Yes
                    Me.DataGrid1.DisplayLayout.CellClickActionDefault = CellClickAction.Edit
                Next

Now the sorting is working perfectly..if value=0 i don't want to  display anything in the column

But if i change the line

drStandardNotExist("DisplayText") = "."   

like this

 drStandardNotExist("DisplayText") = " "    the column will fill with 0,1 (No image will come)

Any fixes for this?

Jeena,

If all you specify is the value and the text is empty then it is expected to display the value.  Using a TemplateColumn would allow you to net set any content to display and set a different value that could be used for sorting on the column.  Is this an option for you?

Let me know if you have any questions.

Hi Alan,

   Could you please paste a sample code ..My grid has other columns too.

I i wanted to make this column as a templatedone,i should change all columns,or i can change this column alone..Am a newbie in this controls.

Regards,

Jeena
