Radgrid's detail table doesn't display at all

I am using radgrid control and trying to populate a detail table with it. But records are being displayed in the master table but detail table is not being displayed at all.

Is dynamic loading from client to populate a child grid possible?

For this example dataset with 6 columns and 6 rows:

AAA BBB CCC 1 2 3

AAA BBB CCC 4 5 6

DDD EEE FFF 1 2 3

GGG HHH III 1 2 3

GGG HHH III 4 5 6

GGG HHH III 7 8 9

Some user operation will result in a call to a webservice, which populate the parent grid. eg.

var tableView = $find("<%= RadGrid2.ClientID %>").get_masterTableView();

tableView.set_dataSource(result);

tableView.dataBind();

My web service returns the distinct first 3 columns, I bind the data as noted above, and the results look like this:

+ AAA BBB CCC

+ DDD EEE FFF

+ GGG HHH III

I can then click expand [+], which calls a web service to return the child rows and populate the child grid, yielding:

- AAA BBB CCC

1 2 3

4 5 6

- DDD EEE FFF

1 2 3

- GGG HHH III

1 2 3

4 5 6

7 8 9

I actually have all of the above working, but the only problem is it only works for the first 11 rows. The child grids and expand/collapse buttons are not dynamically added for any rows beyond the 11th when data is bound.

Why not?

My grid structure is defined as follows:

<telerik:RadGrid ID="RadGrid2" runat="server">

<ClientSettings> <ClientEvents OnCommand="RadGrid2_Command" OnHierarchyExpanding="RadGrid2_HierarchyExpanding" OnDataBound="RadGrid2_OnDataBound"/>

</ClientSettings>

<MasterTableView HierarchyLoadMode="Client" ClientDataKeyNames="PositionAreaAppID" RetainExpandStateOnRebind="false" ExpandCollapseColumn-Display="true">

<Columns>

<telerik:GridBoundColumn DataField="Description" HeaderText="Software" HeaderStyle-Font-Bold="true" />

<telerik:GridBoundColumn DataField="Manufacturer" HeaderText="Manufacturer" HeaderStyle-Font-Bold="true" /> <telerik:GridBoundColumn DataField="Version" HeaderText="Version" HeaderStyle-Font-Bold="true" />

</Columns>

<NestedViewTemplate>

<telerik:RadGrid ID="RadGrid3" runat="server">

<ClientSettings>

<ClientEvents OnCommand="RadGrid3_Command" />

</ClientSettings>

<MasterTableView ClientDataKeyNames="PositionAreaAppPrivID" ShowHeader="false">

<Columns>

<telerik:GridTemplateColumn UniqueName="PrivilegeClientTemplateColumn" HeaderText="" ItemStyle-CssClass="" HeaderStyle-Font-Bold="true">

<ClientItemTemplate>

<div><b>#=PrivTypeDescription #:</b> #=Priv1 #</div>

</ClientItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

</NestedViewTemplate>

</MasterTableView>

</telerik:RadGrid>

Is there a different approach that will allow client-side binding of nested grids? I tried using Grouping, NestedViewTemplates, and DataTables, all without the desired result.

I am about to give up on Grid and considering using a LoadOnDemand TreeView customized with client templates to accomplish this, since i don't need advanced grid functionality like sorting, paging, etc. I am just using it to display in a tabular format.

When I return true in asp:Button OnClientClick it doesn't postback form.

When I return true in asp:Button OnClientClick it doesn't postback form.
I have
<asp:Button ID="btnReplace" runat="server" OnClientClick="return confirm('Are you sure?');" Text="Replace Schedule"></asp:Button>
inside of <asp:Panel ID="pnlMeetingDetails" runat="server">
and pabel is inside of RadAjaxManager
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
When I click btnReplace and select Ok in confirm dialog it doesn't make postback and server event btnReplaceSchedule_Click(object sender, EventArgs e) isn't called. If I remove OnClientClick in btnReplace it works fine. How to make client confirm script work together with RadAjaxManager?

05. </td>

06. <td>

07. <telerik:RadColorPicker ID="color" runat="server" Enabled="true" SelectedColor='<%#System.Drawing.ColorTranslator.FromHtml(Eval("Color").ToString())%>'

Binding a Search box to a list box?

I have a list box, with a lengthy list of items (Interests List Box). A user selects which Interests are likes, and they populate into a different list box for Likes (Likes List Box)

To make searching for specific things easier, I would like to use a search box to help narrow down results. Here is a quick snippet of examples of some of my items:

<telerik:RadListBoxItem runat="server" Text="Music-Country" />
<telerik:RadListBoxItem runat="server" Text="Music-Rap" />
<telerik:RadListBoxItem runat="server" Text="TV-Cartoons" />
<telerik:RadListBoxItem runat="server" Text="TV-Drama" />

So if I type "Music" in the search box, I would like it to filter down and show results that start with "Music-" so they do not have to scroll all the way through the Interests List Box to get there. Once they find what they are looking for, I want them to be able to click the option they were looking for and add it to the Likes List box. I am having trouble finding a way to link the list box and search box together, is this possible?

RadListView SelectedIndexChanged event firing twice .

Hi everyone,

I have a RadListView that is bind to Db. I have to show details of the items in listview when user clicks on the each item . But i am facing issue when its SelectedIndexChanged event is firing. When user clicks on the item for the first time, the detailed data shown is correct but as soon as a second item is clicked , it shows exception :

ArgumentOutOfRangeException :
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Exception is thrown when :

ItemID = ItemListView.SelectedValue.ToString();

Showing data as similar to a demo - http://demos.telerik.com/aspnet-ajax/salesdashboard/
Employee ListView -> clicking showing - > sales data

Also i found that the selectedindexchanged event is firing twice in some cases. Cannot predict such cases but want to know the reason why it is firing twice when user clicks only once.

please advice

Nested tabstrip clearing parent pageviews on postback

We have a nested tabstrip with dynamically created tabs from the code behind. The parent tabstrip is also dynamically created and populated. When the page first loads both the parent tab pageviews and child tab pageviews are correct and both can be navigated. But when the child tabstrip has a postback created by a contained form, the pageviews for the parent tabstrip clear (except for the current open tab with the form). The parent tabs remain but no content underneath (except the current page with the child tabs). The content can only be repopulated by reloading the full page. Note that a form postback at the parent page level does not clear the tab pageviews.

We've tried variations of loading the tabs at postback and not postback but can't seem to find a combination that works.

Is there a way to correct this issue?

thanks!
