I have the following aspx code in a usercontrol:

<telerik:RadTabStrip ID="radTSCapabilities" runat="server" SelectedIndex="0" Skin="Default" MultiPageID="radMPCapabilities" />

<telerik:RadMultiPage ID="radMPCapabilities" runat="server" SelectedIndex="0" />

I dynamically create the Tabs and PageViews from the code behind on load. Inside the PageView is a RadTreeView. See code below:

Telerik.Web.UI.RadPageView tmpPageView = new Telerik.Web.UI.RadPageView();

tmpPageView.ID = type.AbilityType.Name;

radMPCapabilities.PageViews.Add(tmpPageView);

//Add a Tab for the AbilityType

Telerik.Web.UI.RadTab tmpTab = new Telerik.Web.UI.RadTab(type.AbilityType.Name, type.AbilityType.ID.ToString());

tmpTab.PageViewID = tmpPageView.ID;

radTSCapabilities.Tabs.Add(tmpTab);

//Create and Load the Rad Tree

Telerik.Web.UI.RadTreeView radTree = new Telerik.Web.UI.RadTreeView();

radTree.Skin = "Default";

radTree.CheckBoxes = true;

radTree.TriStateCheckBoxes = true;

radTree.CheckChildNodes = true;

radTree.NodeDataBound += new Telerik.Web.UI.RadTreeViewEventHandler(radTree_NodeDataBound);

radTree.ID = type.AbilityType.ID.ToString() + type.AbilityType.Name.Replace(" ", "_");

radTree.DataTextField = "Name";

radTree.DataValueField = "ID";

radTree.DataFieldID = "ID";

radTree.DataFieldParentID = "ParentID";

//If there are multiple Ability Types in result set then go to the DB to get all Abilities for that type

if (distinctAbilityTypes.Count() != 1)

radTree.DataSource = AbilityMgr.GetAbilitiesByAbilityTypeID(type.AbilityType.ID);

else

radTree.DataSource = tmpAbilities;

//Bind the Tree

radTree.DataBind();

//Add a top border

Literal tmpLiteral = new Literal();

tmpLiteral.Text = "<div style='border-top:solid 1px #AAAAAA;'></div>";

//Add the Literal and Tree to the associated PageView

radMPCapabilities.FindControl(type.AbilityType.Name).Controls.Add(tmpLiteral);

radMPCapabilities.FindControl(type.AbilityType.Name).Controls.Add(radTree);

I am trying to get a reference to the dynamically created RadTreeView. I have been unable to do so for some time now. Please help.

set scroll position of a RadSlidingPane?

Hey,

I have a RadSplitter with RadPanes, RadSplitBars, ...
Is it possible to set scroll position of a RadSlidingPane when I'm scrolling an another RadPane?

For exemple, when I click a node in the first RadPane : the same node is clicked in the RadSlidingPane.
When I expand a node in the first RadPane...

But I'd like to have the same rendering when I scroll the first pane and I can't move the content of the RadSlidingPane.

I hope you understand me

Thanks

Michel

minimum and maximum column width for columns

Hi,
I have a radgrid with some image column and other data columns with following configuration.
static headers, column resizing and clip cell content on resize.

I have set image columns width in code behind in pixels and resizable=false. But when I resize other data columns image column also resizes. I don't want them to get resized.

regards,
Mahesh

RadComboBox value when back button pressed

I have a simple search page that contains a a RadComboBox and some text boxes. When the user submits the form it displays results on a new page for the user. When the user hits the browser's back button in IE, the user values in the text boxes and combo box are selected. When I try the same thing in Firefox or Chrome, only the contents of the text boxes are displayed and the combo box reverts to its original value.

I have tried with versions 2008.1.619.20, 2009.1.527.20 and 2010.3.1317.20, but get the same results.

Any thoughts? Is this the expected result for Firefox and Chrome?

Thanks!

calculation for Grid Group Footer Item using javascript

Hi,

I want to calculate total of Quantity column (In Edit Mode) using javascript when I am using group by functionality in Rad Grid. I can do Grand total using javascript but not able to do group by total using javascript as I don't know how to check which group is being edited.

For grand total I am passing Footer value in Java script and deducting it from current value.

Thanks,

Scroll and text nowrap on dropdown

Hi,

I have two questions on the drop down menu. First one should be easier, do you have an EnableAutoScroll as in the RadMenu? I have a drop down that can go beyond the window limits and it would be very useful to have the scroll as there is in the menu.

The second one is a bit more complicated. My drop down is constructed on the client side, and it is based on adding items. However, I noticed that whenever I add first a short text item then a long text item, the long text gets wrapped into two lines or cutoff if I use nowrap. Is there a way to adjust the width of the drop down menu to fit all item texts?

Thanks,
Eduardo

Difficulty accessing Controls in a GridDataItem

I am building a DataTable dynamically at run time and I am also using templates in the Cells that again are dynamically loaded.
The template is currently extremely simple in that it consists solely a CheckBos and a HiddenField like so:

<asp:CheckBox ID="cb" runat="server" /> <asp:HiddenField ID="hf" runat="server" />

I trap the ItemDataBound Event of the Grid and have code similar to that below:

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

DataRowView drv = (DataRowView)item.DataItem;

for (int i = 0; i < rgTags.MasterTableView.Columns.Count; i++ )

{

string uniqueName = rgTags.MasterTableView.Columns[i].UniqueName;

if (drv[i] is System.DBNull)

{

item[uniqueName].Controls[0].FindControl("cb").Visible = false;

}

else

{

AdminTag tag = (AdminTag)drv[i];

((CheckBox)item[uniqueName].Controls[0].FindControl("cb")).Text = tag.sText;

((HiddenField)item[uniqueName].Controls[0].FindControl("hf")).Value = tag.nTagId.ToString();

}

My question is why do I have to have the Controls[0]. before the FindControl() calls? I don't like hard coding things like that and would prefer a more elegant way to find the control in the template.

It is wo0rking now, but it's inelegant and it took me a long time to figure it out and I am sure it will get broken b y a future release.
