Hello

I am using an old version of radgrid (q3 2008) but i hope you can still help me. I have a radgrid on a content page which i am trying to ajaxify. The basic page elements are a search form with a submit button and an asp panel which contains a radgrid. The panel and grid are initially hidden (visible=false) on page load. When the submit button is clicked the grid is loaded with content and the panel is set visible = true. I put the panel and grid inside a rad ajax panel like so...

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" HorizontalAlign="NotSet">

<asp:Panel ID="pnlGrid" runat="server" Visible="true">

<telerik:RadGrid ID="gridJourneys" runat="server" Width="960px" AutoGenerateColumns="False" GridLines="None" skin="SureTrack" ShowFooter="True" Visible="False" EnableEmbeddedSkins="False">

..rest of grid

</telerik:RadGrid></asp:Panel>

</telerik:RadAjaxPanel>

There is a radajaxmanager on the page like so

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnSubmit">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadAjaxPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

When the submit button is clicked the whole page reloads rather than just the grid. Is there somethign wrong with my set up? I can ajaxify the grid inside an asp.net updatepanel but i need to export the grid so I believe i need to use the rad ajax panel

thanks a lot

[Solved] All the text in the grid gets highlike after postback

OK, here is a bit of a weird one. I am building a mail system for a project and when I do a postback event after a double click on a row all the text in the RadGrid is highlighted.

I have a javascript function that simply clicks a image button that I have a post back event on.

    
            function refreshMail(){document.getElementById("ImageButton1").click();}

    
            function RowDblClick(sender, eventArgs){parent.openMailMessage(eventArgs.getDataKeyValue("Idnum"));refreshMail();}

I have a simple Image Button and RadGrid

    
            <asp:ImageButton ID="ImageButton1" runat="server"  
        
                                                ImageUrl="../graphics/refresh2.gif" onclick="ImageButton1_Click"  
        
                                                ToolTip="Refresh mail box." /> 
        
            <telerik:RadGrid ID="RadGrid1" runat="server" AllowCustomPaging="True" 
        
                                    AllowPaging="True" GridLines="None" Height="320px"  
        
                                    HorizontalAlign="Center" PageSize="50" ShowStatusBar="True" Skin="Vista"  
        
                                    Width="760px" AutoGenerateColumns="False" OnDeleteCommand="RadGrid1_DeleteCommand" OnItemCreated="RadGrid1_ItemCreated" 
        
            OnNeedDataSource="RadGrid1_NeedDataSource" ShowGroupPanel="True"  
        
                                    AllowSorting="True" EnableHeaderContextMenu="True"> 
        
                                    <MasterTableView GridLines="None"> 
        
                                    <Columns> 
        
                                    <telerik:GridButtonColumn HeaderText="Delete" ConfirmText="Delete this mail?"  ButtonType="ImageButton" CommandName="Delete" Text="Delete" 
        
                                    UniqueName="DeleteColumn" HeaderStyle-Width="45px"> 
        
            <HeaderStyle Width="45px"></HeaderStyle> 
        
                                        <ItemStyle HorizontalAlign="Center" CssClass="delButton" /> 
        
                                    </telerik:GridButtonColumn> 
        
                                    <telerik:GridBoundColumn DataField="From" HeaderText="From"/> 
        
                                    <telerik:GridBoundColumn DataField="Title" HeaderText="Title"/> 
        
                                    <telerik:GridBoundColumn DataField="Date_" HeaderText="Date" HeaderStyle-Width="120px"> 
        
            <HeaderStyle Width="120px"></HeaderStyle> 
        
                                        </telerik:GridBoundColumn>

                                        <PagerStyle Mode="NextPrevAndNumeric" /> 
        
                                        <RowIndicatorColumn Visible="False"> 
        
                                            <HeaderStyle Width="20px" /> 
        
                                        </RowIndicatorColumn> 
        
                                        <ExpandCollapseColumn Visible="False"> 
        
                                            <HeaderStyle Width="19px" /> 
        
                                        </ExpandCollapseColumn> 
        
                                    </MasterTableView> 
        
                                    <ClientSettings AllowColumnHide="True" AllowColumnsReorder="True"> 
        
                                        <Resizing AllowColumnResize="True" /> 
        
                                        <Scrolling AllowScroll="True" ScrollHeight="280px" UseStaticHeaders="True" /> 
        
                                        <Selecting AllowRowSelect="True"></Selecting> 
        
                                        <ClientEvents OnRowDblClick="RowDblClick" /> 
        
                                    </ClientSettings> 
        
                                    <FilterMenu> 
        
                                        <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                                    </FilterMenu> 
        
                                </telerik:RadGrid>

The code behind

    
            protected void ImageButton1_Click(object sender, ImageClickEventArgs e) 
        
                    { 
        
                        RadGrid1.Rebind(); 
        
                    }

Does anyone have any ideas? What is really weird is that I can call the refreshMail() method from the parent page and it doesnt highlight any text. I'm sure this is a simple one, but it's got me baffeled :/

Thanks in advance,
Matt

Pager customisation

Hi,

I have a RadGrid that I'm using to do some custom paging. This works really well and I'm very happy with how it works. Because the page size of the items I'm displaying changes depending on the selection, I'm changing the VirtualItemCount property to make sure that the number of pages stays consistent, regardless of how many items are displayed. This works well, but it displays on the bottom of the grid (items x to y of total) which obviously changes as the VirtualItemCount changes.

What's the best way to customise just this part of the pager? I've seen in the online demos how to customise the whole thing, but I really just want to access the control that says that and change the text.

I'm using the ItemCreated method as follows:

protected void Grid_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridPagerItem)

...

}

But I don't seem to be able to access the label/literal itself in order to change the text.

Thanks

Export Selected Rows Accross Mulitple Pages

I am working with a grid that has paging and I want to be able to select multiple items across multiple pages and export those items. I have implemented the follow logic to export just selected items

protected void Button1_Click(object sender, EventArgs e)

{

foreach (GridDataItem item in RadGrid1.Items)

{

if (item.Selected==false)

{

item.Visible = false;

}

RadGrid1.ExportSettings.ExportOnlyData = true;

RadGrid1.ExportSettings.OpenInNewWindow = true;

RadGrid1.MasterTableView.ExportToExcel();

}

However, this only works if the grid export settings IngorePaging = False, in which case it only exports the selected items on the current page. If I set IgnorePaging=True, all items are exported all the time.

Is there a way to export selected items across multiple pages?

[Solved] EmptyMessage does not appear when list-box is emptied on the *client*

Hi everyone,

Here's my RadListBox:

<div>

<telerik:RadListBox id="rlbCountries" runat="server" EnableEmbeddedScripts="false" DataTextField="CountryName" DataValueField="CountryID" EmptyMessage="[No countries selected]" Width="100%" Height="250px" SelectionMode="Multiple"></telerik:RadListBox>

</div>

Here's the client-side Javascript code that I use to remove items (countries) after an AJAX call to a web-service:

var rlbCountries = $find(countriesListBoxID);

var items = rlbCountries.get_items();

// clear the current countries

items.clear();

I have found that the list box is correctly cleared; however, the "[No countries selected]" message is not displayed. If I remove the items on the server (via a post-back), the message is shown.

Has anyone else noticed this? Is there something I can do to the list-box object on the client in order for the message to be shown?

embed audio player in radgrid row?

Hi,

Is there a feature or something I can combine with radgrid to play audio in row when a button in a column is clicked?
I don't want user to leave the page to listen to the audio, best way will be a button column for user to click, once the button is clicked, a play will start inside the column and play a wav file.
Any suggestions?

Thanks
Roy
