Hello Boris

If there is not any mistake in code May be I did mistake in design time?On Ultragrid control.I created data schema .set datamember bind[0] and datasource default datasource1.any idea?

Thanks in advance.

Hello,

What are you seeing exactly if it is not a dropdown - just a regular cell? Can you paste here this code you are talking about, I would have to see either a code sample or a small project in order to be able to help you on this.

Borisov could you check this code?It works ,But cant check checkbox.It is not active.Despite I activated.And check column datatype is boolean.

private void besGrid2_InitializeLayout(object sender, InitializeLayoutEventArgs e)
{
DataTable dtb = new DataTable();
dtb.Columns.Add("ID", typeof(Int32));
dtb.Columns.Add("Text", typeof(string));
dtb.Columns.Add("Check",typeof(bool));

dtb.Rows.Add(new object[] { 1, "A" });
dtb.Rows.Add(new object[] { 2, "B" });
e.Layout.Bands[0].Columns[2].Style = ColumnStyle.CheckBox;
e.Layout.Bands[0].Columns[2].CellActivation = Activation.AllowEdit;
e.Layout.Bands[0].Columns[2].CellClickAction = CellClickAction.Edit;
this.besGrid2.DataSource = dtb;
}
