I am trying to add two columns with ultra-combo boxes to Ultra grid. So far I have this code , but I don’t see the column. Why is that.
UltraGridLayout layout = args.Layout;
UltraGridBand band = layout.Bands[0];
band.Columns["Cutsomer"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.DropDownList;
This should help.
HOWTO:What is the best way to place a DropDown list in a grid cell?
Let me know if you still have trouble getting it to work or any questions. :)
Thank you
I tried the version with the value list, I did everithing like in the example. But I dont see even the added column in my grid.
What I am doing wrong
Hi,
I'm not sure what you mean. What "added column" are you referring to? There's nothing in the code you posted here that would add a column to the grid. To do that, you use the band.Columns.Add method. All you have here is code that sets the Style on a column to DropDownList, but doesn't actually provide a list to the column.
This is my code, it doesnt eror out but the column is not added to the grid
private void grdValidShipTo_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e) { // ** Place Event Handling Code Here ** grdValidShipTo.DisplayLayout.Bands[0].Columns.Add("NewColumn", "NewColumn"); grdValidShipTo.DisplayLayout.Bands[0].Columns["NewColumn"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.DropDownList; grdValidShipTo.DisplayLayout.Bands[0].Columns["NewColumn"].ValueList = createFirstValueList(); } private ValueList createFirstValueList() { ValueList vl1 = new ValueList( ); vl1.ValueListItems.Add( 1, "True" ); vl1.ValueListItems.Add( 2, "False" ); return vl1; }
Please could you paste the code as I have arrived at a similar problem and would like to see what you have done to make the combox work
If you want to access the value of a grid cell, then you use the Value property of the grid cell, not the combo. The combo services the entire column, so using the value of the combo would not work.
Thank you I figured out my error. :)
Now I have truble accessing the combo box value inside the grid .
If I tried to access it in the conventional way by combo.Value it is erroring out.
Is there any special way to access it?
Well, that error message is a syntax error in your code and since you didn't provide the code, I can't tell you what's wrong with it.
I figured out how to do that. Now I am trying to filter one of the boxes by the other. I was using cell change event and the event fires in the required time but it gives me the error
The event 'System.Windows.Forms.Control.Layout' can only appear on the left hand side of += or -=
