[Solved] set dropdown selected value in grid on edit

Hi All,

I want to set the dropdown selected value in grid edit mode, 

value should be taken from label which is in ItemTemplate label.

I want to do it in code behind.

Please help me regarding this.

Hi Praveen,

One suggestion would be setting DataKeyNames and setting the DropdownList value accordingly. Give a try with following code.

ASPX:

<MasterTableView AutoGenerateColumns="False" EditMode="InPlace" CommandItemDisplay="Top"
    DataSourceID="SqlDataSource1" DataKeyNames="CustomerID">
    <Columns>
        <telerik:GridTemplateColumn>
            <ItemTemplate>
                <asp:Label ID="Label1" runat="server" Text='<%# Eval("CustomerID") %>'></asp:Label>
            </ItemTemplate>
            <EditItemTemplate>
                <asp:DropDownList ID="DropDownList1" runat="server">
                    <asp:ListItem Text="Item1"></asp:ListItem>
                    <asp:ListItem Text="Item2"></asp:ListItem>
                </asp:DropDownList>
            </EditItemTemplate>
        </telerik:GridTemplateColumn>

CS:

    protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem & e.Item.IsInEditMode)
        {
            GridEditableItem item = (GridEditableItem)e.Item;
            DropDownList dropdown = (DropDownList)item.FindControl("DropDownList1");

            dropdown.SelectedValue = item.GetDataKeyValue("CustomerID").ToString();
        }

    }

Thanks,
Princy.

Thank you for the reply,

Actually i did as follows in aspx

<telerik:GridTemplateColumn DataField="PaymentMode" HeaderText="Payment Mode" 

                                SortExpression="PaymentMode" UniqueName="PaymentMode" EditFormColumnIndex="1">

                                <EditItemTemplate>

                                    <asp:DropDownList ID="ddlPaymentMode" AppendDataBoundItems="true" 

                                        runat="server">

                                        <asp:ListItem Text="Select..."></asp:ListItem>

                                        <asp:ListItem Text="Wire"></asp:ListItem>

                                        <asp:ListItem Text="Cheque"></asp:ListItem>

                                        <asp:ListItem Text="Credit Card"></asp:ListItem>

                                    </asp:DropDownList>

                                </EditItemTemplate>

                                <ItemTemplate>

                                    <asp:Label ID="PaymentModeLabel" runat="server" 

                                        Text='<%# Eval("PaymentMode") %>'></asp:Label>

                                </ItemTemplate>

                            </telerik:GridTemplateColumn>

How to get the label text in c#?

[Princy]

Hello Praveen,

You can access the label in the ItemTemplate of a GridTemplateColumn as shown in the code below:
c#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem dataItem = (GridDataItem)e.Item;
            Label lbl = (Label)dataItem.FindControl("PaymentModeLabel");
        }
     }

Hope this helps..
Princy.
