It does not work. I don't see masked input in the ultragrid column. Moreover, is there any other method??

Is there any way to restrict two decimal places??

Hello rchiu5hk,

I believe that you could still use the MaskInput property of the desired column like:

 ultraGrid1.DisplayLayout.Bands[Key].Columns[Index].MaskInput = "nnnnn.nn";

or the same code but in the IntializeLayout event of the UltraGrid like:

private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
          e.Layout.Bands[Index].Columns[Key].MaskInput = "nnnnn.nn";
        }

Please let me know if you have any other questions.

Can we set the decimal places of indiviual cell?

e.g. I have gird with a doble datatype column. Every row can have different number of decimals point. First row can have the column set as 23.46 whereas another row can have the same column set as 0.0001. 

Can you tell me how this can be achieved. I tried looking mask input for ultragridcell but seems like the column (ultragridcolumn) has the property maskinput and not the cell. 

I have attached a sample project which demonstrates applying a different format to each cell in a column.

could you kind enough to post a sample code using the above editors for two different format in same column (i.e format for each cell in a column?)

I think this can be done, but it depends on exactly what you need to do. You are using the word "format" here, but formatting only applies to a cell that is NOT in edit mode. If the cell is editable by the user and you need different masks based on the row, then you would have to use an editor - like an UltraMaskEditor or UltraNumericEditor control and set the Editor/EditorComponent on the cell. You also need to set the UserEditorMaskSettings property on the column to tell the customer to use the msaking properties of the editor before the column's settings.
