Re: Listview with dropdown and doing edit delete

Oct 07, 2019 09:43 AM|geetasks|LINK

Thanks. But the problem is that dropdown SelectedIndexChanged is not firing.

I had created UserControl. Under that listview is placed. Inside ListView Item Template, I had defined DropdownList. Wondering What can be the reason that dropdown SelectedIndexChanged is not firing?

Hi geetaska,

But the problem is that dropdown SelectedIndexChanged is not firing.

Do you set AutoPostBack="true"?

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
                            <asp:ListItem>1</asp:ListItem>
                            <asp:ListItem>2</asp:ListItem>
                            <asp:ListItem>3</asp:ListItem>
                        </asp:DropDownList>

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
        {
            Response.Write("ddd");
        }

The result:

Yes. Still It was not firing, so I had applied logic on ItemDataBound event and using Jquery. Now, the only prob. is that dropdown changed value is displayed on 2nd postback?

I need detailed code to reproduce your problem, So please post your aspx and aspx.cs code.

and this is new question, please post your question in new thread.

Solved the problem by calling dropdown SelectedIndex changed method forcefully. In Jquery, I had set a variable IsDDClicked=1 and in ListView Bind method, checked if Dropdown is clicked ie if IsDDClicked=1, then fired dropdown Selected index like: dlFndEqu_SelectedIndexChanged(null, null);
