Autopopulate textbox when the dropdownlist column is selected in radgrid in place edit VB.Net

[Supriya]

Hi,

I am using a insert/delete/update radgrid, I have a dropdown list and a textbox in the rad grid, when I select a value in the dropdownlist column, then the textbox should be autopoulated with the data from the database correspoding to the value selected in the dropdownlist. (VB.Net)

For example I have menu table

itemno        |      Description
-----------------------------------
  1              |      XXX
 2               |      YYYYY

So the drop down list contains the itemno, so when the item no 2 is selected, then the Textbox should autopopulate 'YYYYY'

Any help will be highly appreciated

Hi,

You can populate the textbox in SelectedIndexChanged event of the dropdownlist as shown below.
VB:

Protected Sub ddl_SelectedIndexChanged(sender As Object, e As EventArgs)
    Dim ddl As DropDownList = DirectCast(sender, DropDownList)
    Dim item As GridEditableItem = DirectCast(ddl.NamingContainer, GridEditableItem)
    Dim txt As TextBox = DirectCast(item.FindControl("TextBox2"), TextBox)
    txt.Text = ddl.SelectedValue.ToString()
End Sub

Thanks,
Shinu.
