I have written the following code to get value in a dropdownlist and a textbox. The dropdownlist is "ddlSpareParts" and the textbox is "txtSPMCode" . I run a loop to get the value of gridview "grdEditSparePartsMaintenance" and show the result in ddlSpareParts and txtSPMCode . But I get value in textbox but don't get value in dropdownlist. Please solve the problem and help me.

C#

ddlSpareParts.Text = grdEditSparePartsMaintenance.Rows[k].Cells[2].Text.Trim();
txtSPMCode.Text = grdEditSparePartsMaintenance.Rows[k].Cells[4].Text;

Hello Prince,

To read the value from DropDownList you first need to get a handle on the control. Use code similar to one shown below to retrieve a reference to DropDownList. Then you can read the value.

VB

Dim ctrl As Control
Dim row As GridViewRow
Dim ddl as DropDownList 

row = grdEditSparePartsMaintenance.Rows[k]
ctrl = row.FindControl("ddlSpareParts")
ddl = TryCast(ctrl, DropDownList)
txtSPMCode.Text = ddl.SelectedValue

Regards,

You have to add the values in the dropdown.
For e.g. try ddlSparePart.Items.Add(grdEditSparePartsMaintenance.Rows[k].Cells[2].Text.Trim().
