Exactly how you do it depends upon whether you have explicitly added GridBoundColumns or not. Here are some snippets. int fieldNo = this.gridDataBoundGrid1.Binder.ColIndexToField(gridColumnIndex); //if you have explicitly added GridBoundColumns string colName = this.gridDataBoundGrid1.GridBoundColumns[fieldNo].MappingName; //if you haven''t explicitly added GridBoundColumns string colName = this.gridDataBoundGrid1.Binder.InternalColumns[fieldNo].MappingName;

Clay Thanks for the reply. I was trying to do the same thing. but since i have to do it in PrepareViewStyleInfo event it slowing down evreything. Could yo please suggest any other way i can do it. thanks Gulshan

Here is the code i was using int llColumnindex = this.gridDataBoundGrid1.Binder.ColIndexToField(e.ColIndex); string sName = this.gridDataBoundGrid1.Binder.InternalColumns[llColumnindex].MappingName; But i dont think its a good idea to use this code in PrepareViewStyleInfo. Thanks Gulshan

You could create an array of the names so you could retrieve the names just by indexing the array with the e.ColIndex. You could use the above code to create the array in say, FormLoad. If you are allowing your user to move columns, you can handle the grid.Model.ColsMoved event, and then adjust the array (or recreate it).

Clay Clay I have an array which has all the column names in it. Column name keep changing based on certain conditions. I need to paint the background color of the cell based on the column names last character. Here is the code by which i am trying to accomplish this. But its freezing the screen and not working the way i want it to work Please help!!!! if (e.RowIndex > 0 && e.ColIndex > 1) {string lsName = layoutItems[e.ColIndex].ToString(); int ik = lsName.IndexOf("-"); if(ik > 1){ int sLength = lsName.Length; string sDataType = lsName.Substring(sLength - 1 ,1); switch(sDataType) { case "1": e.Style.BackColor = Color.Azure; break; case "2": e.Style.BackColor = Color.AntiqueWhite; break; case "3": e.Style.BackColor = Color.LemonChiffon; break; case "4": e.Style.BackColor = Color.Gainsboro; break; } } } Thanks Gulshan I have this array which has all the column names in it.

Here is a sample that seems to work OK for me. ColNameSample_4393.zip
