Dear Pals ,


    I am facing a problem in datagrid(ASP.NET with VB.net) . I am showing Dependent dropDownLists in datagrid (2 DropDown) as a template column. But I am not being able to fetch the value of first dropdown list on postback of the dropdownlist1 into a variable.

Please Guide me .


Thanks

You have to create an event handler for your dropdown list then access the value in there:

Protected Sub <your dropdownlist>_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
        ''This sub was created by me manually .. since the ddl is not accessable from the page.
        'Then add this: OnSelectedIndexChanged="<your dropdownlist>_SelectedIndexChanged"
        'To the HTML of the ddl in the DG template column.

        Dim <ddlName>As DropDownList = CType(sender, DropDownList)
        some value = ddlEmployee.SelectedValue

Hi Mr Singh...

I am facing a similar problem in my asp.net proj and could not find a definite solution yet.

If you had a solution for dependent dropdowns in datagrid, would appreciate if you could email the same to me at [email protected].

Thanx in advance..

Hi

You can simply add an event on dropdown's change event and fetch the value, e.g. as below:

Event Code on .cs file
protected void ddl_change(object sender, System.EventArgs e)
        {
            DropDownList dList = (DropDownList) sender;
            string ddlText = (dList.Items[dList.SelectedIndex].Text);
        }

Your dropdown in datagrid looks as below:<asp:TemplateColumn>
                                        <ItemTemplate>
                                            <asp:DropDownList OnSelectedIndexChanged="ddl_change" Runat="server" ID="ddl" AutoPostBack="True">
                                                <asp:ListItem Selected="True">-Select-</asp:ListItem>
                                                <asp:ListItem>First</asp:ListItem>
                                                <asp:ListItem>Second</asp:ListItem>
                                            </asp:DropDownList>
                                        </ItemTemplate>
                                    </asp:TemplateColumn>
