Question

I've next code that handle fowFormatting my cells:
private void gridViewRaces_RowFormatting(object sender, RowFormattingEventArgs e)
{
foreach (var cellColumn in e.RowElement.Data.Cells)
{
var cellInfo = cellColumn as GridViewCellInfo;
if (cellInfo != null)
{
cellInfo.Style.DrawFill = true;
if (cellInfo.ColumnInfo.Name == "columnContactProducerName")
{
cellInfo.Style.DrawFill = true;
cellInfo.Style.BackColor = Color.Yellow;
}
else if (cellInfo.ColumnInfo.Name == "columnTransport")
{
cellInfo.Style.BackColor = Color.Yellow;
}
else
{
cellInfo.Style.BackColor = ColorTranslator.FromHtml((e.RowElement.Data.DataBoundItem as RaceForListDto).Color);
}
}
}
//e.RowElement.BackColor = ColorTranslator.FromHtml((e.RowElement.Data.DataBoundItem as RaceForListDto).Color);
}
but my cells aren't painting. How to paint some cells in rows on dataBinding?

Answer 1

It looks like the proper event to do this is ItemDataBound event. See here:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/appearance-and-styling/conditional-formatting
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
//Is it a GridDataItem
if (e.Item is GridDataItem)
{
//Get the instance of the right type
GridDataItem dataBoundItem = e.Item as GridDataItem;
//Check the formatting condition
if (int.Parse(dataBoundItem["Size"].Text) > 100)
{
dataBoundItem["Received"].ForeColor = Color.Red;
dataBoundItem["Received"].Font.Bold = true;
//Customize more...
}
}
}
Or event better is to use a custom CSS class so that you can later make changes without having to rebuild the project:
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e){
if (e.Item is GridDataItem)
{
GridDataItem dataItem = e.Item as GridDataItem;
if (dataItem["Country"].Text == "Mexico")
dataItem.CssClass = "MyMexicoRowClass";
}
}
