Questions on UI for ASP.NET AJAX Forum

1 answer

216 views

I'm learning Telerik UI for ASP.NET AJAX now and I want to know how to use it with an external back-end RESTful API.

Correct me if I'm wrong... Since it is a framework to help us build the UI (front-end), there should be ways to bind the back-end to "give live" to the UI.

I was specting to see some pretty simple straight forward ways to bind data coming from my REST API, but every forum, blog, tutorial that I read so far presents a "hack" to do it.

For instance, the most basic thing... I want to load data to a RadComboBox from my API.

My RadComboBox:

<telerik:RadComboBox ID="regTypeComboBox" runat="server" Width="305" Skin="Telerik" />

How can I use "http://maydomain.com:8080/mycompany/api/registerTypes" to populate my RadComboBox?
Thanks.

GridBoundColumn Date Filter does not work

Hi, I have the following Code to filter a GridBoundColumn. The data comes from a Microsoft SQL DB. For some reason the filtering is not working.

<telerik:GridBoundColumn DataField="TestTimeStamp"

UniqueName="TestTimeStamp" HeaderButtonType="TextButton"

HeaderText="<%$ Resources:Repository,ReportingTimeStamp%>" DataType="System.DateTime"

DataFormatString="{0:g}">

<FilterTemplate>

From

<telerik:RadDatePicker ID="FromOrderDatePicker2" runat="server"

Width="150px" DbSelectedDate='<%# startDate %>'>

<ClientEvents OnDateSelected="FromDateSelected" />

</telerik:RadDatePicker>

<br />

to

<div style="padding-left: 31px;">

<telerik:RadDatePicker ID="ToOrderDatePicker2" runat="server"

Width="150px" DbSelectedDate='<%# endDate %>'>

<ClientEvents OnDateSelected="ToDateSelected" />

</telerik:RadDatePicker>

</div>

<telerik:RadScriptBlock ID="scriptFilterEventDate" runat="server">

<script type="text/javascript">

function FromDateSelected(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

var ToPicker = $find('<%# ((GridItem)Container).FindControl("ToOrderDatePicker2").ClientID %>');

var fromDate = FormatSelectedDate(sender);

var toDate = FormatSelectedDate(ToPicker);

if (toDate != '') {

tableView.filter("TestTimeStamp", fromDate + " " + toDate, "Between", true);

//tableView.filter("TestTimeStamp", fromDate, Telerik.Web.UI.GridFilterFunction.GreaterThan);

}

function ToDateSelected(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

var FromPicker = $find('<%# ((GridItem)Container).FindControl("FromOrderDatePicker2").ClientID %>');

var fromDate = FormatSelectedDate(FromPicker);

var toDate = FormatSelectedDate(sender);

if (fromDate != '') {

//tableView.filter("TestTimeStamp", fromDate, Telerik.Web.UI.GridFilterFunction.GreaterThan);

tableView.filter("TestTimeStamp", fromDate + " " + toDate, "Between", true);

}

function FormatSelectedDate(picker) {

var date = picker.get_selectedDate();

var dateInput = picker.get_dateInput();

var formattedDate = dateInput.get_dateFormatInfo().FormatDate(date, dateInput.get_displayDateFormat());

return formattedDate;

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

</telerik:GridBoundColumn>

Submenu doesn't reopen

Hi,

I have a weird issue with the ribbon menus.

I have a ribbon configured in this way

<telerik:RadRibbonBar ID="RadRibbonBar1" runat="server">

<Tabs>

<telerik:RibbonBarTab runat="server" Text="tab1">

<telerik:RibbonBarGroup Text="group1">

<Items>

<telerik:RibbonBarMenu Size="Large" Text="menu1">

<Items>

<telerik:RibbonBarMenuItem Text="submenu1">

<Items>

<telerik:RibbonBarMenuItem Text="item1"></telerik:RibbonBarMenuItem>

<telerik:RibbonBarMenuItem Text="item2"></telerik:RibbonBarMenuItem>

</Items>

</telerik:RibbonBarMenuItem>

<telerik:RibbonBarMenuItem Text="submenu2"></telerik:RibbonBarMenuItem>

</Items>

</telerik:RibbonBarMenu>

</Items>

</telerik:RibbonBarGroup>

</telerik:RibbonBarTab>

</Tabs>

</telerik:RadRibbonBar>

- Click on the menu1 item, the menu opens

- Move the mouse over the submenu1 item, the submenu opens

- Now move the mouse over the submenu2 item, the previous submenu closes

- Move again the mouse over submenu1, the submenu DOESNT open anymore!

Tested on 2015.2.623.40 and 2015.2.623.45

Any idea on how to fix this?

Thanks

showing and hiding radgrid rows of detail table from client side

Hi,

we have hierarchical radgrid where on expansion of main grid it expands and shows a detail table. each detail table will have multiple records of either type A or Type B. we need to show only one record of type A and one record type B on page load.

The first column of detail table will have an expand button, on click of this it should display all type A rows from client side, and on click of that button it should hide all those rows.

I don't want 3 level hierarchy. since the hidden rows and row with expand button belongs to same level

RadTreeNode expandable but not selectable?

Hi,

I use a RadTreeView to display a multi-level tree of news categories with their respective news items.

I want only the deepest node leveI (being the news item nodes) to be selectable, And so I would like the category nodes to be expandable, but not selectable.

Setting the 'enabled' property of a category node to True also blocks its expandability, so that doesn't work for me.

Can you give me any pointers on how to make a RadTreeNode expandable but not selectable?
Thanks in advance.

Best regards, Marja
