ColumnHeaderCell and GridTableCellStyleInfo

[Simon Fielke]

I have assigned a GridTableCellStyleInfo to the ColumHeaderCell but the style does not appear until I click (and hold the mouse down) on the header cell, as required to sort the column. Is it possible to display assigned style without clicking on it? I tryed the following line; grid.Appearance.ColumnHeaderCell.Themed = false; but this had no effect.

Thank you for your help

Simon, I attached a sample. Look at the ctor. It sets the column header back color to green and just works fine. CS.zip Let me know if you do something different. Thanks, Stefan >I have assigned a GridTableCellStyleInfo to the ColumHeaderCell but the style does not appear until I click (and hold the mouse down) on the header cell, as required to sort the column.

Hi Stefan,
Thanks for your reply and the example code. I am able set the backcolor of the ColumnHeaderCells in my grid, using the sample code that you supplied. However, I am unable to set the GridTableCellStyleInfo of the ColumnHeaderCells. The code I use is below:

GridTableCellStyleInfo cellstyle = new GridTableCellStyleInfo();
cellstyle.BaseStyle = "Header";
grid.BorderStyle = BorderStyle.FixedSingle;
cellstyle.Interior = new Syncfusion.Drawing.BrushInfo(Syncfusion.Drawing.GradientStyle.Vertical, SystemColors.Control, SystemColors.ControlLightLight);
cellstyle.Borders.Top = new GridBorder(GridBorderStyle.Solid, SystemColors.ControlLightLight, GridBorderWeight.Thin);
cellstyle.Borders.Left = new GridBorder(GridBorderStyle.Solid, SystemColors.ControlLightLight, GridBorderWeight.Thin);
cellstyle.Borders.Bottom = new GridBorder(GridBorderStyle.Solid, SystemColors.ActiveBorder, GridBorderWeight.Thin);
cellstyle.Borders.Right = new GridBorder(GridBorderStyle.Solid, SystemColors.ActiveBorder, GridBorderWeight.Thin);
Syncfusion.Drawing.BrushInfo(Syncfusion.Drawing.GradientStyle.Horizontal, SystemColors.Control, SystemColors.ControlLightLight);
Syncfusion.Drawing.BrushInfo(Syncfusion.Drawing.GradientStyle.ForwardDiagonal, SystemColors.Control, SystemColors.ControlLightLight);
grid.Appearance.ColumnHeaderCell.Themed = false;
grid.Appearance.ColumnHeaderCell = cellstyle;

Thanks again for your help,
Simon

Hi Simon,
Try setting this in the QueryCellStyleInfo event handler to see if that helps.

GridTableCellStyleInfo cellstyle;

public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeComponent();

cellstyle = new GridTableCellStyleInfo();
cellstyle.BaseStyle = "Header";

cellstyle.Interior = new Syncfusion.Drawing.BrushInfo(Syncfusion.Drawing.GradientStyle.Vertical, SystemColors.Control, SystemColors.ControlLightLight);
cellstyle.Borders.Top = new GridBorder(GridBorderStyle.Solid, SystemColors.ControlLightLight, GridBorderWeight.Thin);
cellstyle.Borders.Left = new GridBorder(GridBorderStyle.Solid, SystemColors.ControlLightLight, GridBorderWeight.Thin);
cellstyle.Borders.Bottom = new GridBorder(GridBorderStyle.Solid, SystemColors.ActiveBorder, GridBorderWeight.Thin);
cellstyle.Borders.Right = new GridBorder(GridBorderStyle.Solid, SystemColors.ActiveBorder, GridBorderWeight.Thin);

this.gridGroupingControl1.QueryCellStyleInfo +=new GridTableCellStyleInfoEventHandler(gridGroupingControl1_QueryCellStyleInfo);
}

private void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
if(e.TableCellIdentity.DisplayElement.Kind == Syncfusion.Grouping.DisplayElementKind.ColumnHeader)
{
e.Style.Themed = false;
e.Style.ModifyStyle(this.cellstyle, Syncfusion.Styles.StyleModifyType.Override);
}
}
