Questions on UI for ASP.NET AJAX Forum

Hi,

To sum it up: I am trying to resize an iFrame on a RadPane to fit 100% height.

The Scenario: My project is based on the Webmail demo, but in the bottom Pane I want to have an iFrame which correctly resizes then the Splitter is dragged.

I tried to add a client side Javascript block of code on the OnClientResized event of the RadPane, but it does not seem to be triggered and thereby resizing the iFrame.

I don't know if it would be easier to use the ContentURL property to use the RadPane as an iFrame, but do not know how to amend the demo to use a datasource to get the URL as I currently use the same DetailsView as in the demo to effect the iFrame src property. When I set the ContentURL at design time then the Grid does not render any details.

Sorry, but this is my first attempt at using the Telerik AJAX controls.

Regards,
Ray

Uploading different file types in Document Uploader

Hi, I have a Rad Editor that has the document manager to allow the user to upload documents to the server. Now it only allows files with the extension .txt, .pdf, .doc. I would like to also allow it to upload files with other extensions such as .ppt, .zip, .xlsm etc. Is there a way I can do this?

Thanks!

Detail table ChangePageSize Event Not Executing

Hi Telerik Team

I am facing an issue with Detail table view page size change event. In My design I have one MasterTableView and three detail table view as coded below.

<telerik:RadGrid ID="radGrid" AllowFilteringByColumn="true" AutoGenerateColumns="false" runat="server" >
   <MasterTableView Name="masterTableView" runat="server" HierarchyLoadMode="ServerOnDemand">
   <CommandItemTemplate>
   <table width="100%" cellpadding="3px">
   <tr >
      <td align="center">
   <div id="divCommandButtons" runat="server">
   <asp:LinkButton ID="LinkButton1" Text="Button" Visible="false" CssClass="black-button" runat="server" />
   <img id="spacer1" f" border="0" heigth="5" width="0" runat="server"/>
   </div>
   </td>
   </tr>
   </table>
   </CommandItemTemplate>
   <CommandItemStyle HorizontalAlign="Center" Wrap="false" Height="30"/>
   <PagerStyle CssClass="rgPager" />
   <DetailTables >
   <telerik:GridTableView Name="detailTableL1" Width="100%" runat="server" HierarchyLoadMode="ServerOnDemand" >
   <ParentTableRelation>
   <telerik:GridRelationFields DetailKeyField="" MasterKeyField="" />
   </ParentTableRelation>
   <CommandItemStyle CssClass="GridCommand" />
   <CommandItemTemplate>
   <table width="100%" cellpadding="3px">
   <tr>
   <td align="center" >
       </td>
   </tr>
   </table>
   </CommandItemTemplate>
   <PagerStyle CssClass="rgPager" />
   <EditFormSettings EditColumn-UpdateText="<span>Save</span>" EditColumn-InsertText="<span>Save</span>" EditColumn-CancelText="<span>Cancel</span>"/>
   <AlternatingItemStyle BackColor="#F3F6F9" />

and the issue I am facing is with ChanePageSize in Detail Table View. For Master table view when I change its page size its works for me. Also when i tried to move page by page in detail table view it works but when i change page size say 10 to 20 in detail table it not working.

The way i set pager template and size from CS page.

masterView.SetPaging(GridPagerMode.NextPrevAndNumeric);
public void SetPaging(GridPagerMode pagerMode, int pageSize)
   {
   this.GridTableView.AllowPaging = true;
   this.GridTableView.PagerStyle.Mode = pagerMode;
   this.gridTableView.PagerStyle.AlwaysVisible = true;
   }

Thanks..

Problem with grid scrolling in presence of additional controls

Been struggling for some time, have tried support, but not getting a clear answer for what I think is a pretty common scenario. The typical response I get is that at least one element needs to have a fixed height in order to use 100% hieght.

Just looking to make a UI that scales with the browser using Telerik controls. Things work ok with individual controls, things work fine, if you combine controls, then things go bad.

So here is the basic example to start where there is a splitter, tool bar, grid, tab strip and multipage.

Having just a splitter with grids with 100% height works great. Then you want to add some tabs or toolbars, and now the grids cannot calculate 100% height properly (does not account for other control height).

Any recommendations on how to use these controls to properly scale with the browser?

Error 'undefined' is null or not an object opening a radgrid that uses a server control into GridTemplateColumn

I created the following server control by creating the readonly property:

public class RadComboBox : Telerik.Web.UI.RadComboBox

{

private Label lbl = new Label();

private bool _readOnly;

public bool ReadOnly

{

get

{

return _readOnly;

}

set

{

_readOnly = value;

}

protected override void Render(System.Web.UI.HtmlTextWriter writer)

{

if (_readOnly)

{

lbl.Text = this.Text;

lbl.ReadOnly = true;

lbl.RenderControl(writer);

}

else

{

base.Render(writer);

}

if I use this object with RadGrid in GridTemplateColumn fixed in the ItemTemplate ReadOnly to true cause the following JS error message:

Error 'undefined' is null or not an object

radgrid is into a RadAjaxPanel and uses a masterpage that call the RadScriptManager and RadAjaxManager.

I tried to use ajaxSettings instead of RadAjaxPanel but the same error.

how can I fix it?

thanks for any replies

Default focus cannot be set to a button inside RadDock

Hi All,
          Im using my Login Button inside the RadDock and i can't set the defaultbutton property of my page's form tag.Also i cant get my controls in script which is inside RadDock.I solved it by getting the clientID of btLogin .

(ie):document.getElementById("<%=btLogin.ClientID %>")

and same problem might have been occured with defaultbutton .Here is my design.

<form id="form1" runat="server" defaultbutton="btLogin">
<div>
<telerik:RadDockZone ID="rdzLogin" runat="server" Width="100%" Height="350px">
         <telerik:RadDock ID="rdLogin" Title="<b>Login</b>" runat="server" EnableAnimation="true"
             DefaultCommands="None" EnableDrag="false" Skin="Default" EnableRoundedCorners="true">
              <ContentTemplate>
                   <asp:Button ID="btLogin" runat="server" Login" OnClick="btLogin_Click" />
             </ContentTemplate>
        </telerik:RadDock>
</telerik:RadDockZone>
       </div>
</form>

I get the following error while setting defaultbutton in form tag itself and when i remove it no problem occurs :

The DefaultButton of 'form1' must be the ID of a control of type IButtonControl.

Can i set defaultbutton from code behind? Please Help me out...

Regards and Thanks,
Titti.S

Build RadPanelBar - ASPX page never updates

I added a RadPanelBar to my project for the first time today.

It immediately asks that you select "Build RadPanelBar" to begin creating the control.

I go into that, add some test bars, change the text, etc... Then I click OK. In my design view I see the bars, text, font changes, etc... However, in the source view nothing happens. Nothing is changed, so if I make any source changes then everything about my bars is lost. I ended up just editing the RadPanelBar source by hand to add my items and make my font changes.

What am I doing wrong? Why aren't my modifications made through the editor tool working? I click "OK" when I finish and the design view changes, but the source remains empty. It's odd because if I go back into the editor it still has all my settings in there, they just never move over to the Source view.

Is there something I need to do to actually commit the changes made in the RadPanelBar editor to my project?

Grid taking life to load

Hello,

I have a page having a couple of grids

Everything seems working fine, once it is deployed in the server the grids in a specific page is taking life to load if there is no record!

When there is no record, we bind the grid with an object having null reference

Any workarounds?

Thank you

Regards

Drag and Drop Cell

I'm working with the Item Drag and Drop sample, and it works very well. However, I have modified it slightly. The source datagrid has a different number of columns than the destination datagrid. I have modified the code so that when the item is dropped, I manually add the row to the grid. That all works fine, but I really would like to know which column the item was dropped on. Is there a way to get this information?

Thanks,
Derrick.
