GridDropDownColumn - How Do I Get the Value During Update?

[Bryan Kowalchuk]

I have a radgrid that looks like:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="MultiEmployeeList" AutoGenerateColumns="False"

    CellSpacing="0" GridLines="None" GroupingEnabled="False" AllowMultiRowEdit="false"

    AutoGenerateEditColumn="True"  HorizontalAlign="Left"Width="800px">

    <ClientSettings>

        <ClientEvents OnCommand="OnCommand" />

    </ClientSettings>

    <HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">

    </HeaderContextMenu>

    <MasterTableView DataSourceID="MultiEmployeeList" DataKeyNames="rasID" ClientDataKeyNames="rasID"

        EditMode="InPlace">

        <RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

            <HeaderStyle Width="20px"></HeaderStyle>

        </RowIndicatorColumn>

        <ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

            <HeaderStyle Width="20px"></HeaderStyle>

        </ExpandCollapseColumn>

        <Columns>

            <telerik:GridBoundColumn DataField="empName" FilterControlAltText="Filter column column"

                UniqueName="Name" ReadOnly="true">

            </telerik:GridBoundColumn>

            <telerik:GridDropDownColumn DataField="rasRoleID" DataSourceID="RoleList" FilterControlAltText="Filter column column"

                ListTextField="mrrRoleDesc" ListValueField="mrrID" UniqueName="rasRoleID" EmptyListItemText=" -- Select Role --"

                EnableEmptyListItem="True"  >

            </telerik:GridDropDownColumn>

        </Columns>

        <EditFormSettings>

            <EditColumn FilterControlAltText="Filter EditCommandColumn column">

            </EditColumn>

        </EditFormSettings>

    </MasterTableView>

    <FilterMenu EnableImageSprites="False">

    </FilterMenu>

</telerik:RadGrid>

I do an AJAX-type webservice post during update, and it all works fine.
My question is, how can I find the value of the combo box the user has selected during update so I can post this back using a web service?
I can get the key value of the row, but finding the new selected value (rasRoleID) is eluding me.

Thanks.

Hello Bryan,

Try the following code snippet by attaching UpdateCommand event to your RadGrid.

C#:

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)

 {

   if (e.Item is GridEditableItem && e.Item.IsInEditMode)

  {

    GridEditableItem item = e.Item as GridEditableItem;

    string Employee = (item["rasRoleID"].Controls[0] as RadComboBox).SelectedItem.Text;

   }


}


Thanks,
Princy.

Thanks for the reply, but is there any way to get dropdown column value client-side during the OnCommand or other client-side event?

I found the solution. Below is the javascript required:

    function OnCommand(sender, args) {
    args.set_cancel(false);
    if (args.get_commandName() == 'Update') {
        //Get the value, update the service
        var key = sender.get_masterTableView().get_dataItems()[args.get_commandArgument()].getDataKeyValue("rasID");
        var radGridElement = $get('RadGrid1');
        var radRole = $telerik.findControl(radGridElement, "rasRoleID");
        var rasRoleValue = radRole.get_selectedItem().get_value();
        //Update the webservice
        //Create the JSON object
        var request = {};
        request['Source'] = 'MultiRatingRole';
        request['Type'] = 'Update';
        request['Key'] = key;
        request['Value'] = rasRoleValue;
        Service.ProcessRequest(JSON.stringify(request));
    }
}
