Sropdown selected value in edit mode (Radgrid)

[Jagat]

Hi,

I want to use dropdowns in a radgrid.

When i enter into edit mode, i want to show the selected value in the dropdown .

How can i do this?
So far this is my code.

Thanks

<telerik:GridTemplateColumn HeaderText="City">
                        <ItemTemplate>
                            <asp:Label ID="lblcity" runat="server" Text='<%# Bind("CityID") %>'></asp:Label>


                        </ItemTemplate>
                        <EditItemTemplate>

                            <asp:DropDownList ID="ddlCity" runat="server">
                            </asp:DropDownList>


                        </EditItemTemplate>


                        </telerik:GridTemplateColumn>

Code Behind:

protected void gdv_Drivers_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
       {

           if ((e.Item is GridEditableItem && ((GridEditableItem)e.Item).IsInEditMode))
           {
               string where = null;
             //  string cityid = ((DropDownList)e.Item.FindControl("ddlcity")).SelectedValue;
             //  string stateid = ((DropDownList)e.Item.FindControl("ddlstate")).SelectedValue;
             //  string zipid = ((DropDownList)e.Item.FindControl("ddlzip")).SelectedValue;
               DropDownList ddlcity, ddlstate, ddlzip;
               ddlcity = ((DropDownList)e.Item.FindControl("ddlCity"));
               ddlstate = ((DropDownList)e.Item.FindControl("ddlState"));
               ddlzip = ((DropDownList)e.Item.FindControl("ddlZip"));
               myGlobal.LoadDropDown(ddlcity, "tbl_CityLkup", "CityID", "CityNm", "GCRPC", "CityID", "CityNm", where);
               myGlobal.LoadDropDown(ddlstate, "tbl_StateLkup", "StateID", "StateNm", "GCRPC", "StateID", "StateNm", where);
               myGlobal.LoadDropDown(ddlzip, "tbl_ZipLkup", "ZipID", "ZipCd", "GCRPC", "ZipID", "ZipCd", where);


           }

       }

Hello Jagat,

You can attach SelectedIndexChanged event to the DropDownList and access the selected value as shown below.

aspx:

<EditItemTemplate>
     <asp:DropDownList ID="ddlAccountLookup" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlAccountLookup_SelectedIndexChanged">
     </asp:DropDownList>
</EditItemTemplate>

C#:

protected void ddlAccountLookup_SelectedIndexChanged(object sender, EventArgs e)
{
   DropDownList ddl = (DropDownList)sender;
   GridEditableItem item = (GridEditableItem)ddl.NamingContainer;
   string str = ddl.SelectedValue;
}

Thanks,
Shinu.

Hi Shinu,

This event does not fire at all

Edit: Ignore this post. See my next post.

Shinu,

If when the grid loads teh city name for the first row is New York.
When i edit this row, the dropdown list should display "New York" in that row. Then the user wil lselect to change to any other value he wants.

Right now, dropdown is populated, but it is not showing the current value when it goes into edit mode.

In vb.net it would be

ddlCity.SelectedValue = directcast(e.item.DataItem, DataRowView).Item("City")

In C#:

ddlCity.SelectedValue = (DataRowView)e.item.DataItem["City"];

Russ,

Which event should i have it in?
I tried in edit_command, itemdatabound events.

I am getting this error message:

'Telerik.Web.UI.GridItemEventArgs' does not contain a definition for 'item' and no extension method 'item' accepting a
first argument of type 'Telerik.Web.UI.GridItemEventArgs' could be found (are you missing a using directive or an assembly reference?)

Hello Jagat,

You can take a look into the following documentation.
Operations with MS DropDownList in EditItemTemplate of GridTemplateColumn
