I have an framework page in C# that contains several text boxes and buttons.
Each of these buttons contains a CRUD operation.
The page also contains a drop-down list of items linked to the local database.
How can I make this list display a spreadsheet for the desired item

What I have tried:

I want to make the Items dropdown list display only the data table for that item

1 solution

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)

string selectedValue = DropDownList1.SelectedValue;

private void DisplayDataForSelectedItem(string selectedItem)

GridView1.DataSource = GetDataForSelectedItem(selectedItem);

private object GetDataForSelectedItem(string selectedItem)

return null;
