Client Databind Problem

I am utilizing client databinding and I cannot get the grid to populate with
anything. I am returning all my data is JSON format and its verified by
Web Developer Helper. The grid keeps displaying "No records to display.".
Code is posted below. Any ideas.

Ajaxified or not?

I have a page with an AjaxManager on it.

This page opens a modal RadWindow that displays a page that does not have either an AjaxManager or AjaxManagerProxy on it.

This popup page has a RadMultiPage control on it, one page of which contains a RadUpload control and a RadProgressManager.

When I hit the 'save' button on my popup page, the upload starts but the progress manager doesn't.

I can't figure out why.

I wondered if the controls on my popup page where being ajaxified by default as the result of being called by an ajaxified page and if the fact there were no appropriate AjaxSettings was why the progress manager wasn't appearing? TBH, I don't think it is 'cos I'm pretty sure that the upload wouldn't work if the Upload control was ajaxified.

Thoughts?

Problems in exporting radgrid to word and excel files

Hi Everybody,

I have been find a solution but until now I dint solve the problem. I'm going to explain about it.

There is a .aspx page where there is a radgrid. There are also two buttons - word button and excel button.
When the user clicks on word button for example it is invoked its event:

protected

void btnExportWord_Click(object sender, System.Web.UI.ImageClickEventArgs e)

{

RadGrid radGrid = this.getData();

this.ConfigureExportation(radGrid);

radGrid.MasterTableView.ExportToWord();

}

How you can see, I create a new radgrid where it is filled out by getData method. I created a new radgrid because on page, the radgrid has jus some columns and I'd like to export all columns from table to word or excel file.

See the getData() Method:

private

RadGrid getData()

{

RadGrid radGrid = new RadGrid();

radGrid.DataSource = gobjBLProduct.List(

this.Company, this.txtSearch.Text.Trim());

radGrid.DataBind();

return radGrid;

}

Now, See ConfigureExportatio() Method:

private

void ConfigureExportation(RadGrid pradGrid)

{

pradGrid.ExportSettings.ExportOnlyData =

true;

pradGrid.ExportSettings.IgnorePaging =

true;

pradGrid.ExportSettings.OpenInNewWindow =

true;

pradGrid.ExportSettings.FileName =

"List of Product - " + DateTime.Now.ToShortDateString();

}

The problem is when I click on word button there is an exception where it is showed this message: "RadGrid must be DataBound" before exporting."

I didnt undertand why this error. What mistake did i do?

Can anybody help me, please?

Thank you for attention,

Carlos

Focus lost in RadWindow

Hi,

I have a RadWindow in which a page is shown, containing a form. I wish the first RadTextBox in that Form to have focus, which works as it should when the page is loaded directly.
But, when I load the page in a RadWindow (dynamically, as it uses a QueryString for parameters, so the url is set from javascript), none of the Controls have focus.
I have altered the page by adding a line that explicitly sets focus to the control in the page load event, but it didn't work. I finally discovered, that setting ShowContentDuringLoad="true" on the RadWindow solved the problem. But that has a negative effect, because if the RadWindow is opened a second time (with a different QueryString), the old page is displayed while the new is loading, which gives a strange effect.

I have tried adding a javascript function to the onload event of the page, which sets focus to the RadTextBox, but even that seems cancelled by the RadWindow.

How can I make sure that the RadTextBox has focus after opening the page in a RadWindow?

Telerik controls issue in a load balancer environment

Hi

Currently I have integrated a page with Telerik controls to a site that already uses Ajax.
This site is an external site, hence firewall settings, load balancer are all present
Everything works fine in IE6. But the problem is with IE 7.

I have update panels on my page, then Telerik Tree View , editor, toolbar , splitter , rad pane etc.
We have a save button , this save performs an ajax postback. After the ajax postback, any thing that we do throws javascript error , stating "Object does not support this property or function".

Has any one faced this issue before. If so was it solved.
If any details reagarding the configurations can be provided if required.

Any help would be appreciated.
This is occuring in our live environment , when we connect through the internet.

Thanks and Regards
Anumole Mathew

[Solved] Set GridDropDownColumn's DataSource when not in Editing mode

I have a GridDropDownColumn as
<telerik:GridDropDownColumn DataField="CategoryID" DataSourceID="SqlDataSource2" HeaderText="Category" ListTextField="CategoryName" ListValueField="CategoryID" UniqueName="Category"></telerik:GridDropDownColumn>
and the radgrid has DataSourceID="SqlDatSource1". EditMode=InPlace.
It works fine in Edit mode but when it is not in Edit mode, the Category column will show the first value of the DropDown if SqlDatSource1 SelectCommand returns a row with Category is null. How to keep the cell value blank in View mode in this case?
Thanks,

[Solved] Slider Items Flicker on Postback

I have various sliders in my application, and have noticed that every time the page (or even UpdatePanel) posts back, the slider's items flicker. When the slider's items are dynamically retrieved from a database, this flickering is much more noticeable and interfering. I tried implementing a simple slider with only a few hard-coded items, and I still get the flicker (see code below).

    
            <asp:UpdatePanel runat="server" ID="upSlider">  
        
                <ContentTemplate> 
        
                    <telerik:RadSlider runat="server" ID="sldrTest" AutoPostBack="true" ItemType="Item">  
        
                        <Items> 
        
                            <telerik:RadSliderItem Text="Value 1" Value="1" /> 
        
                            <telerik:RadSliderItem Text="Value 2" Value="2" /> 
        
                            <telerik:RadSliderItem Text="Value 3" Value="3" /> 
        
                            <telerik:RadSliderItem Text="Value 4" Value="4" /> 
        
                            <telerik:RadSliderItem Text="Value 5" Value="5" /> 
        
                        </Items> 
        
                    </telerik:RadSlider> 
        
                </ContentTemplate> 
        
            </asp:UpdatePanel>

Is there any way to have my slider persist its items across postbacks, without having to re-draw them? Obviously, if I set AutoPostBack="false" then there won't be any flickering, but I would have no way to handle a value change.

I've already tried the following:

Setting EnableAjaxSkinRendering="true"
Setting EnableViewState="true"
Setting AutoPostBack="false"
Placing slider inside and outside of an <asp:UpdatePanel>
Hard-coding slider items and dynamically adding slider items
