I don't want RadGrid "NeedsDataSource" handler to re-query the database every time the event fires, but I do want it to act on its datasource as it is designed to do. I handle database queries in my "Search" button handler where I get a DataTable and the set RadGid's datasource equal to my datatable. Also, to persist my DataTable, I set a Session variable equal to my DataTable. Then, in RadGrid's "NeedDataSource" I set RadGrid's DataSource equal to my Session variable like the following:

   protected void BindDataTable( DataTable dt)
   {
      RadGrid1.DataSource = dt;
      RadGrid1.DataBind();
      RadGrid1.CurrentPageIndex = 1;
     Session["RADGRIDSOURCE"] = dt;
   }

   protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
    {
       RadGrid1.DataSource = Session["RADGRIDSOURCE"];
    }

I am questioning weather this is the best approach or not. Is there a better way?

keystrokes not recorded in textarea in preview mode

Hi, I am using the radeditor to allow users to create their own templates for responding to radiology studies. I allow the user to create templates by putting the control in design mode. Only textboxes and textareas are allowed in the template. I allow the user to fill in the form fields on the template by putting the control in preview mode. This all works very well except for one problem. I am having a problem with the textarea form element. I am unable to type into the textarea form element in preview mode in IE only (tried version 7 and 8) - it works fine in Firefox and Safari. When I click in the textarea, I get a blinking cursor - but when the first key is hit, the textarea loses focus and the keystroke is not recorded. Is this a known bug? I have version 209.2.826.20.

Thanks,

Ronnie Robertson

[Solved] RadWindows not modal and not resize

Hi,

I have one page with the window component.

<telerik:RadWindowManager ID="RadWindowManager2" runat="server" EnableShadow="true">

<Windows>

<telerik:RadWindow ID="RadWindow1" runat="server" AutoSize="true" VisibleStatusbar="false"

Modal="true">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

I display that with this function.

function openRadWin() {

radopen("criteria.aspx", "RadWindow1");

}

The window opened, and works fine, but the size not change. If I write width= "600px" or heigth="800px" the window size is the same and propertie modal = true doesn't work. I don't know what happened.

I see this example http://demos.telerik.com/aspnet-ajax/window/examples/contenttemplatevsnavigateurl/defaultvb.aspx but not work for me.

Web Part for loading data

Hi everyone!

Can you suggest me an example of a sharepoint webpart used to load a file (for example an excel file, whose content will be copied into a datatable); if possible, a solution that provides that when I click on a text box, the browsing window for file's research is automatically opened and when file is selected by user, the text box is filled with the path of that file.

Thanks in advance.

Gionata.

RadGrid Filter Template by Combo Box. Show All, Null Value as Well Selected Value.

Folks using UI for ASP.NET AJAX Q1 2014 with VS 2012.

I am using below link as Prototype (The Top Grid).

http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultcs.aspx

I would like to Filter the RadGrid Based on Null Value of the City Combobox as Well as All or Selected Value. I modified the Screen (See attached).

Below is my new Datasource for that ComboBox (i.e RadComboBoxCity) that already has some Null City Values.

<asp:SqlDataSource ID="SqlDataSource3"

ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" SelectCommand="SELECT DISTINCT City FROM CustCity"

runat="server"></asp:SqlDataSource>

Also there are Some Null City Values in Customer Table.

<asp:SqlDataSource ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"

ProviderName="System.Data.SqlClient" SelectCommand="SELECT CustomerID, ContactName, ContactTitle, City, Country, Bool FROM Customers"

runat="server"></asp:SqlDataSource>

Any Help is appreciated. Thanks

RadEditor Style Builder Localization Problem

Hi,

I'm trying to translate labels of style builder in the table and cell properties of radEditor. But in style builder window, the tab name does not change. Here is a screenshot of the window. You can see some labels changed on the right pane but the tab name's did not.

I used the :

<data name="StyleBuilder_BorderTab" xml:space="preserve"> <value>Kenarliklar</value> </data>

Is the data name wrong or I'm missing something else?

Thanks,
S. Cicek

[Solved] How do I access the Tooltip (title) property of a RadComboBoxItem in Javascript?

I've created a RadComboBox with a set of RadComboBoxItems that include tooltips.

I have the combobox's OnClientSelectedIndexChanged set to call a Javascript function.

Within that function I'm already able to access the selected value and text.

What I can't seem to find is a way in JavaScript to get to the RadComboBoxItem's ToolTip (Or 'title'. I've already verified that the LI objects have the correct titles.)

format gridnumeric column as KB, MB, GB ?

Hi,

I have a RadGrid with some numeric columns that contain values that represent bytes.

I was wondering if RadGrid has some built in function to format RadGrid column values as KB, MB, GK depending of the number of bytes? (much like windows explorer does in the ""Size" column of the files grid)?

Thanks in advance,

Rutger
