Setting Multicolumn combobox''s header size

[Chin Wye Jin]

Hi,

I have to 3 columns (Column A,B,C),
column C is hidden.
I hope to set the width of Column A and B to fit the maximum dropdownwidth of the multicolumn combobox. while hiding the column C.

I''ve tried some approach but didn''t seem to work.

I''ve attached the codes that i use together with the screen shots on how the result are.

Thanks in advance...

hi Anupama Roy, I''ve actually solve the previous post, but now i got a new problem. i''ve attached 3 pictures of the problem... The first picture is taken when my combo box drop down for the first time. Second picture is when i mouse over my mouse on the drop down grid. which the columns width only change to what i set. The last picture is what i really want my columns to be like. i''m using the codes below to do it: ------------------------------------------------ GridListControl gcontrolShift = this.mcolShiftCode.ListControl as GridListControl; gcontrolShift.Grid.PrepareViewStyleInfo += new GridPrepareViewStyleInfoEventHandler(ShiftGrid_PrepareViewStyleInfo); void ShiftGrid_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e) { if (e.RowIndex > 0 && e.ColIndex > 1) { e.Style.Format = "t"; } if (e.RowIndex == 0) { GridFontInfo fontinfo = new GridFontInfo(); fontinfo.FontStyle = FontStyle.Regular; fontinfo.Bold = false; fontinfo.Size = 8.25F; fontinfo.Unit = GraphicsUnit.Point; e.Style.Font = fontinfo; switch (e.ColIndex) { case 1: e.Style.Text = UIResx.ShopflowDataTracking.ShiftID; e.Style.CellModel.Grid.ColWidths.SetSize(e.ColIndex, 100); break; case 2: e.Style.Text = UIResx.ShopflowDataTracking.ShiftCode; e.Style.CellModel.Grid.ColWidths.SetSize(e.ColIndex, 100); break; case 3: e.Style.Text = UIResx.ShopflowDataTracking.StartTime; e.Style.CellModel.Grid.ColWidths.SetSize(e.ColIndex, 100); break; case 4: e.Style.Text = UIResx.ShopflowDataTracking.EndTime; e.Style.CellModel.Grid.ColWidths.SetSize(e.ColIndex, 100); break; } } } ------------------------------------------------ This problem only occurs when i have more than 2 columns in my dropdown grid. I hope the information tha i provide you sufficient... Thanks in advance.. :)

Hi Jin,

Calling the this.mcolShiftCode.ListBox.Grid.Invalidate(); after setting the cell column widths will solve the issue. Below is a code snippet. Lets us know if this helps.

void ShiftGrid_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
if (e.RowIndex > 0 && e.ColIndex > 1)
{
e.Style.Format = "t";
}

if (e.RowIndex == 0)
{
GridFontInfo fontinfo = new GridFontInfo();
fontinfo.FontStyle = FontStyle.Regular;
fontinfo.Bold = false;
fontinfo.Size = 8.25F;
fontinfo.Unit = GraphicsUnit.Point;
e.Style.Font = fontinfo;

switch (e.ColIndex)
{
case 1:
e.Style.Text = UIResx.ShopflowDataTracking.ShiftID;
e.Style.CellModel.Grid.ColWidths.SetSize(e.ColIndex, 100);
break;
case 2:
e.Style.Text = UIResx.ShopflowDataTracking.ShiftCode;
e.Style.CellModel.Grid.ColWidths.SetSize(e.ColIndex, 100);
break;
case 3:
e.Style.Text = UIResx.ShopflowDataTracking.StartTime;
e.Style.CellModel.Grid.ColWidths.SetSize(e.ColIndex, 100);
break;
case 4:
e.Style.Text = UIResx.ShopflowDataTracking.EndTime;
e.Style.CellModel.Grid.ColWidths.SetSize(e.ColIndex, 100);
break;
}

this.mcolShiftCode.ListBox.Grid.Invalidate();

}
}

Calvin.
