If I use user control to edit grid records can inject property/constructor to my control, or hook to any 'Pre' ItemCreated of the grid that I use event ?

I have a grid that opens up a fancybox on a nested item, it updates the tables and then when the fancybox closes the grid should reload the datasource and rebind.
JS
Code Behind
The problem is that is actually calling the rebind, but the grid doesn't update, then when I click on any other button I get the following error:
Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I can't see why this is happening? Other Rebinds using onClick events are working 100%.

Can someone please advise me on how to reload the grid on closing of a fancybox.

Thank you.

Cannot create an object of type 'System.Decimal' from its string representation '<%=5%>' for the 'Value' property.
What do i wrong?

Hi,

I am using a radgrid to display data and RadMenu control for menu.
If, I reduce the size of the screen and click on filter of one of the columns in RadGrid, the filter menu items are getting hidden behind the RadMenu.

How do I bring the radgrid filter menu over the RadMenu?

Please help.

I have attached the screenshot of the problem.

Thanks,
Aditi

Greetings,

I am currently trying to implement the AjaxSpellCheck into my RadEditor.  I am getting an issue about my dictionaries not existing.  I think the issue is I'm trying to cross domains.  Here is the scenario:

I have one project that has a Wiki within it.  The RadEditor exists here.
My other project, the main project of the site, contains the App_Data/RadSpell/en-US.tdf file, along with the web.config settings.

I'm trying to point the RadEditor to the main project's App_Data for it's dictionary.  Is that possible or does it need to be within the same project?

Kindest Regards,
Chad Johnson

Guys I am sorry I am following the below video tutorial and I am stumped


http://tv.telerik.com/watch/aspnet/radgrid/radgrid-edit-templates 

When I get to the part where I create Form Template. The author goes "You do not want to see me put this controls on" so then it fast forwards tills all the text boxes and buttons are on!!!!!!!

Thats what I want to see? I am new to this and need step by step instructions, if I am going to teach myself.

Is their a video where it shows you how to add the controls to a template?

. 

I am using RadControls for ASP.NET AJAX Q1 2012 in my current project.

I have a web page which has a RadNumericTextBox and a RadGrid.

The RadGrid has In Place edit mode and only accepts double value on each cell.

I need to do the following on the web page :
1. After the user enters a value on the RadNumericTextBox, display a background colour on the RadNumericTextBox depending on the value entered.
2. After the user enters a value on each RadGrid cell, display a background colour on the RadNumericTextBox depending on the  value entered.

The background colour needs to be displayed as soon as the value has been completely entered.

Can you please help me how to do this?

Thanks,
Herman

I had a problem that I just could not understand why it would not work.
I use enums at times to populate dropdowns. For an example

[DataContract]
[Serializable]

public enum Corporate
{
  [EnumMember] [Description("FD")] COMPANY,
  [EnumMember] [Description("IB")] INDUSTRY,
  [EnumMember] [Description("KD")] PRIVATE,
  [EnumMember] [Description("SLE")] SLEIPNER
}

I want Company, Private etc to be populated in the dropdown and then get the description value back.
Well, this has nothing to do with Telerik so far. My problem was when in my datacontract I was using nullable
and wanted to use filter in my RadGrid. It would not work. I debugged my could and
found that the FilterExpression was set to "([Corporate] = INDUSTRY)". Now, this is just plain wrong.
It should be "([Corporate] = 'INDUSTRY')". Note the single quotation marks.

I fixed this issue by adding DataType="System.String" and then the filtering looked ok, but nope
it still did not work.

Why did it not work?

Well, it turned out that when I was using

[DataMember]
public Corporate Corporate { get; set; }

in my contract it works, but when using a nullable property

[DataMember]
public Corporate? Corporate { get; set; }

it did not work.

I fixed it by adding another class called searchcriteria and use that one
for my initial search containing my nullable Corporate and then my original class without nullable
for the filtering. This is very irritating. Can someone at Telerik look into this matter.

Best regards,
Claes

Hi,

Title has a typo...
How to set column width to fit, when UseStaticHeaders="true"

I have a RadGrid which likes this:

            <telerik:RadGrid ID="CRMGrid" runat="server" AllowSorting="true" GridLines="None" OnSortCommand="CRMGrid_SortCommand" OnItemDataBound="CRMGrid_ItemDataBound" AllowMultiRowSelection="true" OnSelectedIndexChanged="CRMGrid_SelectedIndexChanged" ShowHeader="true">
                <HeaderStyle Width="100px" />
                <ClientSettings EnableRowHoverStyle="true" EnablePostBackOnRowClick="true">
                    <Selecting AllowRowSelect="true" />
                    <Scrolling AllowScroll="True" UseStaticHeaders="true" FrozenColumnsCount="1"/>
                </ClientSettings>
                <SelectedItemStyle CssClass="SelectedItem" />
                <MasterTableView Font-Names="Arial,sans-serif" TableLayout="Auto">
                    <Columns>
                        <telerik:GridClientSelectColumn>
                            <HeaderStyle Width="35" />
                            <ItemStyle Width="35" />
                        </telerik:GridClientSelectColumn>
                    </Columns>
                    <CommandItemSettings ShowExportToCsvButton="true" />
                    <HeaderStyle Font-Bold="true"/>
                </MasterTableView> 
            </telerik:RadGrid>

If UseStaticHeaders="true", then header and content are in 2 <div> and 2 <table> tags, table layout is fixed and column width can NOT be fit to max length of cell content. See picture 1.
If UseStaticHeaders="false", then header and content are in same div and table, column width is auto-fit, but header disappears when scroll down.See picture 2.

Any suggestion?
Thanks a lot.
