Reload specific controls after a child window closes

I have a master page...content page...usercontrol that contains a radgrid. From that radgrid I launch an edit form into a radwindow using a custom url in the itemcreated event. The edit form contains various controls but at the end of the edit form I will have 2 textboxes and a button. If the user needs to change the values of those 2 textboxes they must open another form to perform various database operations to retrieve the new values. I am saving values into Session so they will be available across the application. My question is how can I implement a delegate to reload the values of just those the textboxes when I close the child form. I am not as up on delegates as I need to be.

[Solved] RadDatePicker doesn't show Calendar properly

Hi!
By default RadDatePicker displays its Calendar below DateInput, but I need to display it above. In the help I've found how to implement it using JavaScript, and it works in general. A problem comes when I disable and then enable RadDatePicker with JavaScript. After that when I click on DatePopupButton the Calendar appears for a short moment and then disappears.
Here is my aspx-page code:

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

<head runat="server">

<title></title>

</head>

<body>

<telerik:RadCodeBlock ID="radCodeBlock" runat="server">

<script type="text/javascript">

function enableDTPicker(isEnabled)

{

var dtStartDate = $find("<%=dtStartDate.ClientID %>");

if (dtStartDate != null)

{

dtStartDate.set_enabled(isEnabled);

dtStartDate.get_calendar().set_enabled(isEnabled);

dtStartDate.get_popupButton().disabled = !isEnabled;

}

function PopupOpen()

{

var picker = $find("<%= dtStartDate.ClientID %>");

var textBox = picker.get_textBox();

var popupElement = picker.get_popupContainer();

var dimensions = picker.getElementDimensions(popupElement);

var position = picker.getElementPosition(textBox);

picker.showPopup(position.x - 10, position.y - dimensions.height - 5);

}

</script>

</telerik:RadCodeBlock>

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

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

<table>

<tr><td><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /></td></tr>

<tr>

<td>

<table border="0" cellspacing="0" cellpadding="3" width="100%">

<tr>

<td><asp:RadioButton ID="option1" Text="option1" GroupName="group1" runat="server" Checked="true" /></td>

<td> </td>

</tr>

<tr>

<td><asp:RadioButton ID="option2" Text="option2" GroupName="group1" runat="server" Checked="true" /></td>

<td>

<telerik:RadDatePicker ID="dtStartDate" runat="server" Enabled="true">

<DatePopupButton onclick="PopupOpen();" Enabled="true" />

</telerik:RadDatePicker>

</td>

</tr>

<tr>

<td><asp:RadioButton ID="option3" Text="option3" GroupName="group1" runat="server" /></td>

<td> </td>

</tr>

</table>

</td>

</tr>

</table>

</form>

</body>

</html>

It's cs-file:

using System;

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

option1.Attributes.Add("onclick", "enableDTPicker(false);");

option2.Attributes.Add("onclick", "enableDTPicker(true);");

option3.Attributes.Add("onclick", "enableDTPicker(false);");

}

In the beginning the RadDatePicker control is enabled, and click on DatePopupButton opens Calendar properly. If I select option1 or option3 the RadDatePicker becomes disabled. Then I select option3, and the RadDatePicker becomes enabled again, but after clicking on DatePopupButton the Calendar just appears and then disappears in a moment.

Why is that and how can I fix it?
Thank you

[Solved] Toolbar skin

Hi,
I just created 2 new skins for tollbar as in your example.
I created new folder with the name Header (for one skin) and copied all the images and the ToolBar.Header.css file.
I changed few properties in the skin but still have 2 problems:
1) How to remove the black border from the items in the toolbar dropdown?
2) How to remove the place for images and align the text to the left.

I attached the file for better explanation.

[Solved] RadGrid and Advanced databinding issue

Hi,

I was trying to get ExcelML based export working. I was able to achieve some formatting and other Goals using ExcelML but as for ExcelML based export we need to implement Advanced databinding using NeedDataSource event, I had to do some changes to my existing code - which i did.
The problem I am facing now after doing all the changes is:

Page data source is changing as per requirement but page is not showing changed data. It's staying one step back. Here is scenario:

1. Page has a drop down with 3 types, suppose A, B and C.
2. First time page shows data depending upon the selection which is A.
3. I change selection to B. Page posts back, datatable is re-built and Grid's dataSource is Set to it but not ReBinded (as stated by Telerik). Page is still showing data shown previously i.e. data for type A.
4. I change selection to C. Page posts back, datatable is re-built and Grid's dataSource is Set to it but not ReBinded. Now page shows data for type B - which was selected in step 3.
5. If you keep changing the selection. Page shows data for previous type i.e. one step previous. Please note that datasource is built and set properly but page's view is not updated.

I tried rebinding the Grid and it some times works properly but it crashes other times. what to do? Any help?

Thanks.

[Solved] Massive Data with Multi Columns and LoadOnDemand

Hi Telerik Team,

I'm using the ComboBox with Multi Columns using the OnItemsRequested event and LoadOnDemand.

However my datatable is about 100K records. How can I handle this in RadComboBox?
It is giving me error: "Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property."

The idea is I do not want to change the maxJsonLength property. I want the ComboBox to load only the items requested and not all the data once with the EnableVirtualScrolling property enabled.

Please do let me know how can I achieve such scenario.

P.S.: I do not want to go with RadGrid inside the RadComboBox.

Thanks,
Bilal
