Conditional Image in Wingrid Cell
posted

Hi there,

I'm looking for some advise on getting an image into my wingrid cell correctly. I have tried a few different things with some strange results, most likely I'm missing the point somewhere along the lines...

OK I have a grid (always a good start), a column called priority (with values like high, medium, low etc). When the grid row is initialised I find the priority cell's value. If the cell is high I want to replace the text in the cell from the word "high" to an exclaimation mark image (16x16 png).

So...

public void gridTasks_InitializeRow( sender,... e )

string myValue = ( string )e.Row.Cells["Priority"].Value;

if ( myValue.ToLower() == "high" )

{
e.Row.Band.Columns["Priority"].CellAppearance.Image = Icons.exclaimation_red;
//e.Row.Band.Columns["Priority"].CellAppearance.ImageBackground = Icons.exclaimation_red;

e.Row.Band.Columns["Priority"].CellDisplayStyle = CellDisplayStyle.FullEditorDisplay;
//e.Row.Band.Columns["Priority"].CellButtonAppearance.Image = Icons.exclaimation_red;

e.Row.Cells["Priority"].Value = "";
}

What's really strange is I can step through the debugger and see myValue is "high", every 3rd or 4th row but every row comes back with the priority column cell with the image in it. I don't think this is the best way of applying the image to a cell so is there a better way?

Can I use a Layout appearance e.g.

// e.Row.Cells["ImpactId"].Appearance = grid.DisplayLayout.Appearances["Positive"];

Cheers,
John
