Horizontal Panelbar?

Hi there,

I was wondering if you could tell me whether there are any plans to create a panelbar that expands horizontally - my thinking is an accordion-style menu capability where the tabs (vertical) slide the panels out along the x axis such as here:

(I realise that one is flash-based, but you get the idea!)

Problem when I try to edit an specific row

Hi mates,

I have a radgrid and a external textbox and button to search specifics rows in the radgrid. Basically I change the SelectCommand of the RadGrid DataSource when I use the search button.

The first column of the radgrid is the following:

<telerik:GridTemplateColumn UniqueName="EditarEstado" ItemStyle-HorizontalAlign="Center" AutoPostBackOnFilter="false">
    <HeaderStyle Width="50px" />
    <ItemTemplate>
          <asp:ImageButton ID="btnEditarEstado" CommandName="Edit" runat="server" ImageUrl="~/img/buttons/edit.png"
          CommandArgument='<%# Eval("id") %>' ToolTip="Modificar" />
    </ItemTemplate>
</telerik:GridTemplateColumn>

If I search an specific row using the textbox and the search button, the row is showed successfully in the radgrid. The issue happens if I try to edit that row using the btnEditarEstado ImageButton. When I clic on it, autopostback is executed and the default SelectCommand of the radgrid datasource is set, so, it's like if I try to edit the first row and not the row that I searched.

How could I edit the selected row and not the default first one, please?

Please, let me know if you have any problem to understand my problem.

Thanks a lot in advance.

Cheers.

RadGrid does not adjust height when groups are collapsed

Hi,

I have a RadGrid with height=300px, it does not adjust it's height when groups are collapsed. I would like it's height to be 300px or less and show scrollbars when needed. When groups are collapsed, it shows whitespace as seen in given image to fill grid height. How can I adjust grid height when groups are collapsed?

I want grid height to adjust like in this demo.

Thanks,
Prava

RadRating becomes read only and losses style after postback using a Modal popup

I have a RadRating on a page that if clicked runs javascript that opens a modal. The modal pop-up contains a "separate" RadRating module. Everything work fine until the form on the modal popup is submitted. This asp:Button-based submission saves to db; generates a postback; and runs javascript that hides the modal.

What javascript do I need to use to reload my RadRating after postback from a Foundation 5 reveal modal popup? (more about modal http://foundation.zurb.com/docs/components/reveal.html)

var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
// What do I put here to re-initialize the RadRating on the main page?
});

On Demand web service call retry?

We're trying to work around a possible network/browser issue at a client site. Occasionally the on demand web service call is failing. The request the browser makes is completely empty. Any subsequent call succeeds. Is there any way to retry the web service call up to 3 times before returning an error? It's easy enough in jQuery, but I can't find how to manage the calls myself with the RadComboBox

Thanks.

radnumerictextbox input type

For the love of HTML5 and push for mobile compatibility please modify radnumerictextbox to allow for HTML 5 numeric input type. For years I have seen all the responses from Telerik to just use the RadTextBox. The radnumerictextbox has better support for numbers, yet lacks the most basic COOL feature for mobile. Inputtype = number.

CheckBox values from Grid with paging

Hi,

i have a problem with picking up Check Box values from the Data Grid, where the option sorting, paging, etc. is allowed.

My ASPX code is shown below:

<telerik:RadGrid ID="gvUsers" EnableViewState="true" runat="server" AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True" CellSpacing="0" OnSortCommand="gvUsers_SortCommand" OnGroupsChanging="gvUsers_GroupsChanging"

OnPageIndexChanged="gvUsers_PageIndexChanged" OnPreRender="gvUsers_PreRender" ShowGroupPanel="True" OnPageSizeChanged="gvUsers_PageSizeChanged" PageSize="2" ShowFooter="True" Skin="Sunset" style="table-layout:fixed;" AutoGenerateColumns="False" GridLines="None" OnNeedDataSource="gvUsers_NeedDataSource">

<ClientSettings AllowDragToGroup="True">

</ClientSettings>

<GroupingSettings CaseSensitive="false" />

<GroupPanel Text="<%$Resources:localization, lblGroupingText%>"></GroupPanel>

<MasterTableView DataKeyNames="UserID" AutoGenerateColumns="False" ClientDataKeyNames="UserID" Width="100%">

<Columns>

<telerik:GridTemplateColumn UniqueName="cbSelect" AllowFiltering="false" ShowFilterIcon="false">

<ItemTemplate>

<asp:CheckBox ID="cbSelectUser" runat="server" OnCheckedChanged="cbSelectUser_CheckedChange"

AutoPostBack="True" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="UserID" FilterControlAltText="Filter ID column" HeaderText="ID" ReadOnly="True" SortExpression="UserID" UniqueName="UserID" CurrentFilterFunction="EqualTo" AutoPostBackOnFilter="true" ShowFilterIcon="false" HeaderStyle-Width="30px" FilterControlWidth="30px"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="FullName" FilterControlAltText="Filter Full name column"

HeaderText="<%$Resources:localization, lblUserFullName%>" SortExpression="FullName" UniqueName="FullName" CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" ShowFilterIcon="false" HeaderStyle-Width="150px" FilterControlWidth="145px"></

telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Email" FilterControlAltText="Filter email"

HeaderText="<%$Resources:localization, lblEmail%>" SortExpression="Email" UniqueName="Email" CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" ShowFilterIcon="false" HeaderStyle-Width="150px" FilterControlWidth="145px"></

telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="RoleName" FilterControlAltText="Filter role column"

HeaderText="<%$Resources:localization, lblUserRole%>" SortExpression="RoleName" UniqueName="RoleName" CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" ShowFilterIcon="false"  HeaderStyle-Width="200px" FilterControlWidth="230px"></

telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="StatusDescription" FilterControlAltText="Filter Status column"

HeaderText="<%$Resources:localization, lblStatus%>" SortExpression="StatusDescription" UniqueName="StatusDescription" CurrentFilterFunction="Contains" AutoPostBackOnFilter="true" ShowFilterIcon="false"  HeaderStyle-Width="100px" FilterControlWidth="80px"></

telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Created" FilterControlAltText="Filter date created column"

HeaderText="<%$Resources:localization, lblDateCreated%>" SortExpression="Created" UniqueName="Created" AllowFiltering="false" AutoPostBackOnFilter="true" ShowFilterIcon="false"  HeaderStyle-Width="100px" FilterControlWidth="80px"></

telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Modified" FilterControlAltText="Filter date modified column"

HeaderText="<%$Resources:localization, lblDateModified%>" SortExpression="Modified" UniqueName="Modified" AllowFiltering="false" AutoPostBackOnFilter="true" ShowFilterIcon="false"  HeaderStyle-Width="100px" FilterControlWidth="80px"></

telerik:GridBoundColumn>

</Columns>

<PagerStyle AlwaysVisible="True"/>

</MasterTableView>

</telerik:RadGrid>

Because the paging does not persist the checked Check Box values, i have additional two methods which stores and sets the checked values on page change: PreRender and OnCheckedChange:

protected void cbSelectUser_CheckedChange(object sender, EventArgs e)

{

ArrayList selectedItems;

if (Session[Constants.SelectedGridItems] == null)

{

selectedItems = new ArrayList();

}

else

{

selectedItems = (ArrayList)Session[Constants.SelectedGridItems];

}

foreach (GridDataItem item in gvUsers.MasterTableView.Items)

{

CheckBox chkSelected = (CheckBox)item.FindControl("cbSelectUser");

String Id = item["UserID"].Text;

if (chkSelected.Checked)

{

if (!selectedItems.Contains(Id))

{

selectedItems.Add(Id);

}

Session[Constants.SelectedGridItems] = selectedItems;

}

else

{

selectedItems.Remove(Id);

Session[Constants.SelectedGridItems] = selectedItems;

}

and

protected void gvUsers_PreRender(object sender, EventArgs e)

{

if (Session[Constants.SelectedGridItems] != null)

{

ArrayList selectedItems = (ArrayList)Session[Constants.SelectedGridItems];

Int16 stackIndex;

for (stackIndex = 0; stackIndex <= selectedItems.Count - 1; stackIndex++)

{

string curItem = selectedItems[stackIndex].ToString();

foreach (GridDataItem item in gvUsers.MasterTableView.Items)

{

CheckBox box = (CheckBox)item["cbSelect"].Controls[1];

if (curItem.Equals(item.OwnerTableView.DataKeyValues[item.ItemIndex]["UserID"].ToString()))

{

box.Checked = true;

}

On the Page, i also have an Button which is outside the Grid. On the Button_Click it should pick up all Check Box values from the grid, not only those from current page. I tried it with "AllowPaging = false" and Rebind(), but after the rebind method is executed, no one Check box is checked...

How to get it work?

Thanks, Adnan
