[Solved] Dynamic Template column Problem

Hi,
As per my requirement, i need to create template column programmatically (I don't know columns of data source at design time).
Am able to add template columns programmatically but data in columns lost in postbacks.
To overcome this, i moved columns adding logic to OnInit event, but same set of columns are adding again and again between postbacks.
I tried

gv1.MasterTableView.Columns.Clear(); and gv1.Columns.Clear(); methods but they have not worked for me.

Please help me to fix this. Sample code will be greatly appreciated.

Thanks,
Sumanth

Grid to occupy 100% of screen and scroll

Hello,

I have a grid which need to occupy 100% of screen and has lot of columns.

If I give the fixed property it is streched to occupy 100% of the screen but the columns are so condensed and hence the page lacks readability

Is there anyway to stretch the grid to 100% of screen and have horizontal scroll bars to view those columns which are beyond right margin?

Thank you

Regards
Raj

storing expanded state serverside callback

hi telerik team,

I have a clientside timer control, a radxmlhttppanel and a radtree. the timer updates the radtree every 10 secondes. it works great, but i have to keep the actual state of the tree after the refresh!

I found following example: http://www.telerik.com/help/aspnet/treeview/tree_store_expanded_callback.html

but if i collapse a node, after the refresh the node is expanded again...

regards,
ingemar

[Solved] Can't access combo inside panel from client side

I have two comboboxes that are inside a panel control. The panel's visibility is false initially. When the user selects an option, the panel with the 2 combo boxes is made visible. Depending on what the user selects in the first combo box, I need to enable or disable the second combo box client side. However, I am unable to access the combo using $find('<%= cbxAdminAction.ClientID %>').

I have also tried accessing the combo boxes usingTelerik.Web.UI.RadComboBox.ComboBoxes. I was able to find the combo controls in the Firebug console. However, when the page loads, Telerik.Web.UI.RadComboBox.ComboBoxes[14] is out of range.

How do I access the combo boxes from client side?

The function below is wired to the onClientSelectedIndexChanged event for the first combo box.

01.function EnableSubActionDropDown(combo, eventArgs)

02.{

03. var value = Telerik.Web.UI.RadComboBox.ComboBoxes[14].get_value();

04.

05. if (value != "99")

06. {

07. Telerik.Web.UI.RadComboBox.ComboBoxes[15].disable;

08. }

09. else

10. {

11. Telerik.Web.UI.RadComboBox.ComboBoxes[15].enable;

12. }

13.}

I am loading a control into a page that has a RadGrid. NeedDataSource is being called too soon!

I have code that loads the control that contains the radgird like this:

if (ControlToLoad == "ConCapitalDetailsPS")

{

Financial.ConCapitalDetails ucConCapitalDetails = Page.LoadControl("~/Grants/Phases/Financial/ConCapitalDetails.ascx") as Financial.ConCapitalDetails;

ucConCapitalDetails.ID = "ConCapitalDetailsPS";

PhaseContent.Controls.Clear();

PhaseContent.Controls.Add(ucConCapitalDetails);

ucConCapitalDetails.ActivePhase = ActivePhase;

ucConCapitalDetails.BindData();

}

But the problem is I need to load my data into the grid with

protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

So this is being called before I have the chance to load a specific data into the page

//int iGrantID = ActivePhase.GrantId;

//int iPhaseID = ActivePhase.Id;

So what I need is somehow be able to set properties on that user control BEFORE the NeedDatasrouce so that the NeedDataSource has the parameters it needs.. How would I do that? The cheating way is perhaps just make a session variable but that seems ugly.. here is the rest of the relevant code (The control being called )

[Solved] Popup Edit Localization Error

Hi,
I am using this code on page which includes masterpage for center popup edit but when i click close button on popup edit form it gives me error.

The numeric part ('159.5') of '159.5px' cannot be parsed as a numeric part of a Pixel unit.

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
   var popUp;
   function PopUpShowing(sender, eventArgs)
   {
       popUp = eventArgs.get_popUp();
       var gridWidth = sender.get_element().offsetWidth;
       var gridHeight = sender.get_element().offsetHeight;
       var popUpWidth = popUp.style.width.substr(0,popUp.style.width.indexOf("px"));
       var popUpHeight = popUp.style.height.substr(0,popUp.style.height.indexOf("px"));
       popUp.style.left = ((gridWidth - popUpWidth)/2 + sender.get_element().offsetLeft).toString() + "px";
       popUp.style.top = ((gridHeight - popUpHeight)/2 + sender.get_element().offsetTop).toString() + "px";

RadSiteMap Skin

Hello Telerik.
I am using RadSiteMap in my application. But I am not able to set the skin of it as shown in the link
http://demos.telerik.com/aspnet-ajax/sitemap/examples/nodelines/defaultcs.aspx
Here is what I did:

<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" EnableEmbeddedSkins="false" Skin="Custom" />

<telerik:RadSiteMap ID="RadSiteMap1" runat="server" ShowNodeLines="True" EnableEmbeddedSkins="False"

Skin="Custom">

<Nodes>

<telerik:RadSiteMapNode runat="server" NavigateUrl="~/Administrator/AdminHome.aspx"

Text="Administrator Home" ToolTip="Administrator Home">

<Nodes>

<telerik:RadSiteMapNode runat="server"

NavigateUrl="~/Administrator/DeleteRoutine.aspx" Text="Delete Class Routine"

ToolTip="Delete Class Routine">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode runat="server" NavigateUrl="~/Administrator/DeleteUser.aspx"

Text="Delete User" ToolTip="Delete User">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode runat="server" NavigateUrl="~/Administrator/RoutineFileUpload.aspx"

Text="Upload Class Routine" ToolTip="Upload Class Routine">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode runat="server"

NavigateUrl="~/Administrator/UsersProfileEdit.aspx" Text="Edit Profile"

ToolTip="Edit Profile">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode runat="server"

NavigateUrl="~/Administrator/UsersProfileView.aspx" Text="View Profile"

ToolTip="View Profile">

</telerik:RadSiteMapNode>

</Nodes>

</telerik:RadSiteMapNode>

</Nodes>

</telerik:RadSiteMap>

I am using using actually black skin as the machine where I will run my application does not have Telerik installed, so I copy and attach the skin directory to my project and call these as:

<link href="../CustomSkin/SiteMap.Custom.css" rel="stylesheet" type="text/css" />

<link href="../CustomSkin/FormDecorator.Custom.css" rel="stylesheet" type="text/css" />

Everything is fine except the black background as shown in the above link. What else should I add to get that one.
Thank you.
And lastly Telerik is awesome.

IE6/Sub Menu Flyouts

We're having an issue with IE6 and menus with a third level in them. You have the top menu, which is clicked, and another menu displays. Some of these items have other items under them which when hover over it, it displays another level of items. When we do this however, we're getting "Object doesn't support this property or method". Has anyone else run across this. It works in IE7 and 8, but not in IE 6. The items never display, we just get a JavaScript error.

Thanks,
Adam

How to iterate through visible timeslots

Let's say I have the RadScheduler showing in week mode with each slot shown in intervals of 2 hours...

How can I (in code-behind) get all of the timeslots visible for the current week so that I can iterate through each slot and enable/disable it based on some business rules I have.

Is there a way to do this?
