Hi

 i set the column value to the dropdownlist  or DropDownValidate.But not solved.Same text values which are filled from datatable not matched with dropdownlist values even though both are same.if i need id values from cell i have to select some text value from the dropdownlist attached to the cell then it shows selected value in blue color.by default when filled from datatable those are not matching with dropdown item values.Anu code added to match both values?

e.Layout.Bands[0].Columns[3].ValueList =

this.ultraDropDown1;

private

void BindUltraDropDown()

{

DataTable dt = new DataTable();

dt.Columns.Add(

"ID", typeof(int));

dt.Columns.Add(

"DisplayText", typeof(string));

dt.Rows.Add(

new object[] { 0, "A" });

dt.Rows.Add(

new object[] { 4, "B" });

dt.Rows.Add(

new object[] { 5, "C" });

dt.Rows.Add(

new object[] { 1, "A" });

dt.Rows.Add(

new object[] { 2, "B" });

dt.Rows.Add(

new object[] { 3, "C" });

dt.AcceptChanges();

this.ultraDropDown1.DataSource = dt;

this.ultraDropDown1.ValueMember = "ID";

this.ultraDropDown1.DisplayMember = "DisplayText";

}

private void BindGrid()

{

DataTable dt = new DataTable();

dt.Columns.Add(

"ID", typeof(int));

dt.Columns.Add(

"DisplayText", typeof(string));

dt.Columns.Add(

"Dropdo");

dt.Columns.Add(

"dropdoqwn1");

dt.Rows.Add(

new object[] { 1, "A", "A", "A" });

dt.Rows.Add(

new object[] { 2, "B", "A", "A" });

dt.Rows.Add(

new object[] { 3, "C", "A", "A" });

dt.AcceptChanges();

ultraGrid1.DataSource = dt;

ultraGrid1.DataBind();

}

What you have here looks like it should work, but  it's very difficult to do anything with a code snippet like this, since there are too many unknowns in the project.

Can you post a small sample project that I can run and debug to see the problem? To attach a file to your forum posts, just go to the Options tab.

Hi,

What do I need to do with this sample in order to see a problem occur?

I tried dropping down the list and selecting an item in the first row of the grid. For example, I select "B" and then I move to another Row (or click the button). Your AfterRowUpdate code is getting the value from the DataRow and it correctly returns a 2.

Then I tried the same thing without dropping down the list, but instead I typed a "B" into the cell and clicked the button. Once again, I get the same results. Your code in AfterRowUpdate returns the number 2.
