ListView datasource loaded twice on browser back button

Hello,

I have a page with ListView and filters surrounded with RadAjaxPanel (let's say 'Page A'). If any of filters changes, I save the previous state in history (using RadScriptManager AddHistoryPoint). It all works just fine, history is being populated every time I change filter(s) and after clicking browser's back button, ListView loads data with previous filters.
The problem comes up, when I navigate from 'Page A' to any other page in my web project. Then if browser's back button is hitted, ListView loads datasource which has been loaded at the beggining (before any of history points were made) and after approximately 1 second, loads datasource to the one stored in history.
I want, that only datasource from the history is loaded, without the datasource from the start.

Thanks for your reply,
Aleš.

Separator Line Height

Hi,

Is it possible to set the line height for rows that are marked as separators?
Separator rows have the same height as other rows, but I would like to reduce them if possible.

I have tried altering the css file by adding a height to rcbseparator - but this had no effect. The combobox is being used for both Template and Non-Template dropdowns.

Thanks
Shimon

OnResponseEnd not firing with RadMultiPage

Hi,

I've got a page with a RadAjaxManager on with an OnResponseEnd method. It had a single Formview on the page, ajaxified by the RadAjaxManager. In this scenario, the OnResponseEnd method of the RadAjaxManager was called when the Formview updated, as expected.

I've now placed a RadTabStrip on the page, with an associated RadMultiPage control. I've added a RadPageView to the RadMultiPage, and placed my Formview in the RadPageView. Now, the Formview still appears to be ajaxified by the RadAjaxManager, but the OnResponseEnd javascript method is never fired.

Any ideas?

Thanks,

Matt

TreeView NodeClick and AjaxPanel

I spent a few hours ripping my hair out over this one - but it appears that there is a bug in the NodeCheck event in RadTreeView. It may be specific to Firefox/Mozilla, and i've tried the no-cache fix, with no luck.

As an example, create a TreeView with checkboxes=true, and populate it with say 10 nodes in the Page_Load event. Add a NodeCheck server side event (the function can be empty). Wrap the TreeView in an AjaxPanel, and run the project.

<telerik:RadAjaxPanel ID="rap2" runat="server">

<telerik:RadTreeView runat="server" ID="tv1" CheckBoxes="true" onnodeexpand="tv1_NodeExpand" onnodecheck="tv1_NodeCheck" >

</telerik:RadTreeView>

</telerik:RadAjaxPanel>

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

tv1.Nodes.Clear();

for (int i = 0; i < 10; i++)

{

tv1.Nodes.Add(new RadTreeNode(i.ToString()));

}

Check off all the boxes, and hit refresh on the browser (CTRL-R or F5). When the page reloads, either none of the nodes will be checked, or only the first node will be checked. It appears that the ViewState is not being saved after a NodeCheck event.

The hack solution i have for the time being is to add in an OnClientNodeChecked handler with the following:

function ClientNodeCheck() {

var tree = $find("<%= tv1.ClientID %>");

tree.UpdateState()

}

Could you please confirm if this is in fact a bug, and if there will be a fix for this in an upcoming release?

Thanks,

N.

Too many spaces in field definition

I am using the latest version of RadControls (2011.2.712.40) and am running into a confusing issue. I have a grid defined with a GroupByExpression like so:

<GroupByExpressions>

<telerik:GridGroupByExpression>

<GroupByFields>

<telerik:GridGroupByField FieldAlias="Status" FieldName="RealStatus" SortOrder="Descending" />

</GroupByFields>

<SelectFields>

<telerik:GridGroupByField FieldAlias="Status" FieldName="RealStatus" />

</SelectFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

When the page loads the grid looks exactly how I want it to, however when I hit the "Add" link (auto-generated in the Command header along with a Refresh link) I get "Too many spaces in field definition: ' RealStatus Status DESC'."

Since the page initially loads fine and only postbacks cause it to die I have no clue what could cause this. If I don't have the SortOrder specified postbacks function as expected (albeit in the wrong order) which is even more confusing.

Any ideas?
