I have a telerik radgrid along with several gridbound columns. I want to reload the grid with the new data on a button click (which deletes one of the rows) without doing a posting back and refreshing the page.

But I am not sure how to use the telerik ajax manager, I have it as follow:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" >
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="myGrid">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="myGrid" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

then, I have a LinkButton when onclick it fires the btn_OnCommand on server side, which rebinds myGrid with the new retrieved data. But I won't see the changes on client unless I refresh the page. Could someone point me how to use the ajax manager?

Thanks

Unable to add calender control in radgrid Filter

Hi,
I am using Telerik.Web.UI.dll version 2008.1.515.20
I need to add Calender control and a Drop Down control in Filter of radgrid asp.net.
But the <FilterTemplate> Tag is missing.
I tried to achieve this functionality using <

telerik:GridDateTimeColumn>

But the problem here is when i edit my row it shows calendar controls for each row also which is not required.
I need Calender control only in Filter rad grid.

RadGrid Rendering differently in Different Machine of 100% Same Application

I have a .NET 4.0 application which uses RadGrid in a web-page in Visual Studio 2013. When I open my page on 1st machine, I got the following HTML,

<div id="ctl00_mainContentPlaceHolder_ctl00_mainContentPlaceHolder_radMainPanel">

<div id="ctl00_mainContentPlaceHolder_radMain" class="RadGrid RadGrid_Metro">

<img width="64px" style='max-height: 100px; max-width: 100px;' src="/Data/Images/2013_09_16_17_18_37_1837_30f9.jpg" />

</td><td>

and when I open the same page on second machine I got,

<div id="ctl00_mainContentPlaceHolder_ctl00_mainContentPlaceHolder_radMainPanel">

<div id="ctl00_mainContentPlaceHolder_radMain" class="RadGrid RadGrid_Metro">

<table class="rgMasterTable" id="ctl00_mainContentPlaceHolder_radMain_ctl00" style="width:100%;table-layout:auto;empty-cells:show;">

<colgroup>

<col style="width:35px" />

<col />

...............................................................

The second one is correct but why my first machine does not show any table element which is the root cause.

Accessing checkbox control

Hi, I just updated our Telerik ASP.NET AJAX Radcontrols from Q3 2009 to Q3 2013, and the following code is not working anymore (see below), can somebody help me please?

The page has this declaration in the DetailView part of the RadGrid (inside columns):

                                    <telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn2" DefaultInsertValue="">
                                        <ItemTemplate>
                                            <asp:Panel ID="Panel2" runat="server">
                                                <asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("band") %>' OnCheckedChanged="checked_value" AutoPostBack="True"></asp:CheckBox>
                                            </asp:Panel>
                                        </ItemTemplate>
                                    </telerik:GridTemplateColumn>

This checkbox can be checked by the user and needs to be extracted to be able to gather selected rows in master/detail grid.
The code that used to work is:

                    foreach (GridDataItem gdi in RadGrid1.Items)
                    {
                        if (gdi.ItemType == GridItemType.Item ||
                            gdi.ItemType == GridItemType.AlternatingItem)
                        {
                            try
                            {
                                if (gdi["CheckBoxTemplateColumn2"] != null &&
                                    ((CheckBox)gdi["CheckBoxTemplateColumn2"].FindControl("CheckBox2")).Checked)
                                {
                                    if (gdi["deliveryNote"].Text.Trim() != " ")
                                        deliveryNote += gdi["deliveryNote"].Text + ",";
                                    materialDocument += gdi["MaterialDocument"].Text + ",";
                                    purchaseOrder += gdi["purchaseOrder"].Text + ",";
                                }
                            }
                            catch (Exception ex)
                            {
                            }
                        }
                    }

The exception is entered when C# tries to execute this: gdi["CheckBoxTemplateColumn2"] and in debug it is throwing exception too.

Any help would be much appreciated.

Regards, Pieter

Change Active Tab

I am utilizing the following example "Standalone Multipage" to work with my tab strip and have implemented it just fine. However I would really like it to update the tab location as well. How can I go about doing this? So when you click "Next" on the CU Type tab it will then highlight "Filters", so on and so forth.

Also I noticed when running it that if I manually clicked on "Dates" tab and clicked next it would go to the next tab which could be "Filters", not "Saved Searches".

Quite possibly this is the wrong sort of application for this? Is the Wizard a better use of it?

<telerik:RadTabStrip ID="RadTabStrip1" runat="server" SelectedIndex="0" MultiPageID="RadMultiPage2">

<Tabs>

<telerik:RadTab ToolTip="CU Type" Text="CU Type" Selected="True"></telerik:RadTab>

<telerik:RadTab ToolTip="Filters" Text="Filters"></telerik:RadTab>

<telerik:RadTab ToolTip="Fields" Text="Fields"></telerik:RadTab>

<telerik:RadTab ToolTip="Dates" Text="Dates" Enabled="True"></telerik:RadTab>

<telerik:RadTab ToolTip="Saved Searches" Text="Save"></telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

Is there anyway to include some text to the left of the Export to Excel button icon in the top right of a RadGrid? I do know that you can change the mouse-over text.

Thanks,
