Can each combobox in a datagridview column have unique values and if so how?

[svaradan]

Hi

I have a situation where in I have two combo boxes in a datagridview control. The first combo box items are all static. But the second combo box items need to change based on the first combo box value selected. The problem I am running into is if I bind the datasource to the column the values are all the same all the time. Please help.

Thanks for the information. It still is not helping me since my current situation is this.

I have a datagridview which has two combobox columns. I want the items listed and available for selection to change on one combobox to change based on the item selected on the other.

Hopefully this gives a clearer picture.

And thanks for helping me out with this issue.

In order two have two combobox columns that one is based on the previose one you have to do the following:
* Create a global bindingSource
BindingSource filteredCmbColu mn2= new BindingSource() ;
DataView dv = new DataView(dtCmbC olumn1);//create a dataview from the first cmbColumn.
filteredCmbColu mn2.DataSource = dv;//secend column's datasource is the dataview from first cmbColumn.

In the event: Cell_BeginEdit( )
// Set the combobox cell datasource to the filtered BindingSource
DataGridViewCom boBoxCell dgcb = (DataGridViewCo mboBoxCell)data gridview1[e.ColumnIndex, e.RowIndex];
dgcb.DataSource = filteredCmbColu mn2;

// Filter the BindingSource based upon the region selected
this.filteredCm bColumn2.Filter = "..."

In the event Cell_EndEdit()
// Reset combobox cell to the unfiltered BindingSource
this.filteredCm bColumn2.Remove Filter();
