Dynamically/Programmatically Creating a Control in GridTemplateColumn

Hello, all.

I have a tricky dynamic/programmatic creation issue which is I think different from any of the other ones I've been reading about here, i.e. "how do I programmatically create a column?", "how do I programmatically create a grid?" etc. I'm familiar with all the online references regarding those and have no problems there. My scenario:

I have a RadGrid that is declared statically in the ASPX page.
This RadGrid contains all GridBoundColumns, except for one GridTemplateColumn.
In this GridTemplateColumn, I have only an empty <ItemTemplate></ItemTemplate> declared. (I also tried declaring an empty <EditItemTemplate></EditItemTemplate>, makes no difference.)
Based on a condition that is only available after the RadGrid is databound (i.e. I perform a check on the contents of a column, similar to "((TextBox)gridItem["RenderHint"].Controls[0]).Text")...
...I then dynamically create a control and add it to the GridTemplateColumn (e.g. create a TextBox tb, then do something like "gridItem["Value"].Controls.Add(tb);"). I've found that since the condition is based on the data in the item, I need to do this step in ItemDataBound.

Everything I've described so far works perfectly. So here's where the trouble begins.

When it comes time to persist data back to the DB, in my ItemCommand for the RadGrid which receives the "Save" (from e.CommandName), I have a call to GridEditableItem.ExtractValues. This call to ExtractValues finds and pulls data for every other column (which is in edit mode at any rate), except for my GridTemplateColumn! As described above, this is the column where I am dynamically instantiating and adding a control.

If I perform the instantiation and addition earlier as a test (e.g. Page_Init), then of course the control is found - but my condition which is based on data is not yet available. In other words, even though I would love to build the grid programmatically in Page_Init, I can't do so because I don't know what kind of control I need to instantiate that early!

Ideas please? Regards,

Allen

Clicking kills menu

Hi,

We are using ExpandDelay in combination with ClickToOpen.
When users that are in a hurry clicks around in menues, it sometimes ends up in a state where sub-items can't be opened anymore.

Sample:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="menu.aspx.vb" Inherits="TestaTredjepartWeb.menu" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="s" runat="server">

</asp:ScriptManager>

<div>

<table>

<tr>

<td>

<telerik:RadMenu ID="menu" runat="server" RenderMode="Lightweight" ClickToOpen="true" ExpandDelay="1000">

<Items>

<telerik:RadMenuItem Text="Test1" Value="item1">

<Items>

<telerik:RadMenuItem Text="1"></telerik:RadMenuItem>

<telerik:RadMenuItem Text="2">

<Items>

<telerik:RadMenuItem Text="22"></telerik:RadMenuItem>

<telerik:RadMenuItem Text="23"></telerik:RadMenuItem>

</Items>

</telerik:RadMenuItem>

<telerik:RadMenuItem Text="3"></telerik:RadMenuItem>

</Items>

</telerik:RadMenuItem>

<telerik:RadMenuItem Text="Test2" Value="item2">

<Items>

<telerik:RadMenuItem Text="1"></telerik:RadMenuItem>

<telerik:RadMenuItem Text="2"></telerik:RadMenuItem>

<telerik:RadMenuItem Text="3"></telerik:RadMenuItem>

</Items>

</telerik:RadMenuItem>

</Items>

</telerik:RadMenu>

</td>

</tr>

</table>

</div>

</form>

</body>

</html>

In this sample do the following:

Click the Test2 menu item to open it
Move the cursor fast to Test1 item and click it before it open by itself (within 1 second since ExpandDelay=1000)
Keep the mouse over the Test1 so it opens by itself
When this has happened, the sub-items below Test1 (2->) can't be opened in any way until the menu is closed by clicking beside the menu!

You might think that this doesn't happen often, but for some users it actually does.
One other thing is that I think the second click should open it directly without waiting for the expandelay...

Regards
Andreas

[Solved] What is best way to provide license agreement functionality ?

Hi,
I am using "UI for ASP.Net AJAX Q2 2014", Telerik.Web.UI.dll version is 2014.2.618.45 and Visual Studio 2013, developing a website.

On one of my webpage, upon a button click, I need to open up license agreement and need to ask user to "Agree" in order to continue. If user presses Disagree, want to take some actions serverside.
I have a RadGrid, inside ItemTemplate, I have a linkButton and I want to open up this license agreement, based on a data field value, so lets say if that datafield value is "1" it should open up license agreement, if that datafield value is "0", it do not need to open up that license agreement. But if it opens up license agreement, I should be able to get "Agree" and "Do not Agree" on serverside.

<asp:LinkButton ID="lnkAddProduct"

CausesValidation="true" ValidationGroup="ValidationGroup2"

ToolTip="Add To Cart"

runat="server" CommandArgument='<%# Eval ( "PriceListID").ToString() %>'

CommandName="addproduct"><img style="border:0px" alt="" width="22px" height="22px" src="../Images/icons/shopcartapply3.ico"/> </asp:LinkButton>

So I want to display license agreement text upon click of a button, with Agree and Do not Agree buttons, and want to code on both "Agree" and "Do not agree" click.
For License Agreement Text, I am fine using PDF to display or can also display Text, whatever is easy.

What I want to know is, is there any way to achieve above functionality using any of the Telerik Control?

RadGrid: GridTemplateColumn with RadComboBox not showing value in grid or insert/update

I recently changed a regular GridBoundColumn to a GridTemplateColumn so that it may serve as a RadComboBox instead of a textbox which allows users to choose from a dropdownlist or type in their own value which can be dynamically saved to the list. I do this in the Insert/Update methods of the Radgrid which will update the tables for the dropdownlists just fine. However, the RadGrid itself no longer finds a value for the column and inserts NULL into its actual column. I will break it down

RadGridTable
Columns: ClaimantID, StartDate, EndDate, NoteStatus

RadComboBoxTable
Columns: NoteStatusID, Text, ect.

The RadGrid has an aspx sqldatasource with an Insert command into the RadGridTable. This worked perfectly fine.
I added a new OnInsertMethod through C# that will grab the value from RadComboBox and put it into the RadComboBoxTable. This now works fine but on insert and update the value NULL gets put into the RadGridTable. Every other value works just fine.

Here is my RadComboBox:

<telerik:GridTemplateColumn FilterControlAltText="Filter NoteStatus column" HeaderText="Note Status" SortExpression="NoteStatus" UniqueName="NoteStatus" Visible="true">
<ItemTemplate>
<%#DataBinder.Eval(Container.DataItem,"NoteStatus") %>
</ItemTemplate>
<EditItemTemplate>
<telerik:RadComboBox ID="rcbNoteStatus" runat="server" DataField="NoteStatus" Text='<%#DataBinder.Eval(Container.DataItem,"NoteStatus") %>' EnableLoadOnDemand="true" OnItemsRequested="rcbNoteStatus_ItemsRequested" DataTextField="Description" DataValueField="Status" ></telerik:RadComboBox>
</EditItemTemplate>
</telerik:GridTemplateColumn>

Hide/Show SearchBox from javascript

Hi,

I am trying to toggle the visibility of a searchbox on my page using a button.
but for some reason the searchbox never disappear.

<asp:ImageButton

ImageUrl="Images/zoom-search-2-icon.png"

AlternateText="Search"

ToolTip="Search"

Height="32"

Width="32"

runat="server"

CssClass="iconImageStyle"

OnClientClick="Search_Click()" />

<telerik:RadSearchBox

ID="CmbBx_Search"

runat="server"

Width="550px"

EmptyMessage="Search..."

OnClientSearch="PerformSearch"

ShowSearchButton="true">

<DropDownSettings Height="400" Width="300" />

<WebServiceSettings Path="Main.aspx" Method="GetResults" />

</telerik:RadSearchBox>

<script type='text/javascript'>

function Search_Click() {

toggle_visibility('CmbBx_Search');

}

function toggle_visibility(id) {

var e = document.getElementById(id);

if (e.style.display == 'block')

e.style.display = 'none';

else

e.style.display = 'block';

}

</script>

From the code behind if I change the Visibility, it works.
But I do not want to do this from the code behind. I need to do it from client-side javascript.

RadAsyncUpload and selected file

Hi,

Is there a good way of implementing a way of selecting one of the uploaded files (e.g. with radio button) that an action will be performed on?
Optimally I would like to see it in the the list of files, for example in front of the file names.

Currently I am doing this by filling a RadCombobox box with the list of file names, but the UI is somewhat cluttered and not very transparent.

Thanks,
Markús

Multiple grids and pagination

Hi all -

I'm new to these controls.

I have a page that is using three grid controls. One of the three controls is dependent upon successful data selection by the user from one of the other grids; the user selects the desired parameters via checkboxes and then clicks a button to populate the third grid. While all three are initially populating successfully, that third grid can have a lengthy result set and when I attempt to move to another page the grid empties and I get the default 'no data' message that I assigned to the 'NoMasterRecordsText' property although none of the other data on the page has changed. Do I need to do something specific in the postback perhaps to get the pagination to work correctly?

Thanks in advance!
