推荐答案

protected void ddlRole_SelectedIndexChanged(object sender, EventArgs e)
{
string _selectedText = ddlRole.SelectedItem.Text;//to get the text of selected item
if (ddlRole.SelectedItem.Value != "Operational user")
{
txtUser.ReadOnly = true;
txtUser.Text = ddlRole.SelectedItem.Text;
ScriptManager.RegisterClientScriptBlock(Page, GetType(), "Disable", "Disable()", true);
}
else
{
txtUser.ReadOnly = false;
txtUser.Text = "";
ScriptManager.RegisterClientScriptBlock(Page, GetType(), "Enable", "Enable()", true);
}
ddlRole.Items.FindByText(_selectedText).Selected = true;
}
