[Solved] Help needed displaying grid detail row/nested view with dynamic layout

I need to display grid with pending changes to a set of records. The way I envisioned it, each master row would be a record itself. When you expand the row, the pending changes would be presented in a detail row. However, since each row will have different pending changes, the layout of this detail row would be different. I wanted to hide/display columns of each individual detail grid depending on pending changes to their master row record. So, if there's no pending change to a property, the corresponding column on this row will be hidden. I've attached the picture illustrating my attempt.
I can't find a way to hide columns of the detail view for an individual row and I don't know if it's even possible. Does layout for each detail view have to be the same? Is detail view even a right way to accomplish this? Should I use nested view instead?
I'd appreciate help pointing me to the right approach with some tips on what event handlers I should use to accomplish this.
Thanks,
Alex

RadGrid embedded RequiredFieldValidator Text property not working

I am using a RequiredFieldValidator and a ValidationSummary within a usercontrol within RadGrid EditForm.

The validation works fine, but I have set the RequiredFieldValidator to show an * beside the control being validated (Text="*") and the ErrorMessage to something more discriptive: ErrorMessage="Name is required."

The problem however is that when the cotrol errors out, ErrorMessage shows in both the ValidationSummary and next to the erroring control where the * is expected per the property (Text="*"). I need the * to show because it is better for my layout and consistent with validation outside the radgrid elsewhere on the page. The longer more verbose Message="Name is required."
messes up the layout.

Has anyone had this problem before. I have never seen the RequiredFieldOperator behave like this before so I can only see the RadGrid as being the problem.

Someone please help.

x Axis item label alignment

For a bar chart, as the rotation angle for the x axis item label increases, the label continues to be centered on the series item. When the x axis becomes crowded, it is impossible to determine what label is associated with a series item. Other vendors products have the ability to align the upper end of the x axis item label with the series item that it is associated with. Is there a way to accomplish this either the RadChart or RadHtmlChart?

Field names not populating in rad filter

I have followed the example on the site for implementing the RadFilter with a grid. The control displays, but I get the following error:

Line: 6
Error: Sys.WebForms.PageRequestManagerServerErrorException: Parameter cannot be null or empty.
Parameter name: fieldName

This occurs whenever I click the add expression button.

Any help would be appreciated.

Thanks...Brian

RadGrid popup disabled by combo box event function?

Just had something odd happen.

I have a fairly conventional RadGrid with a FormTemplate popup editor. This has been working normally.

On the FormTemplate is a RadComboBox and I've been trying to attach a function call to the OnClientLoad event with the eventual intent of doing some intialization to the popup.

This function is defined as follows:

function cbLoad(sender) {
var curVal = sender.get_value();

    if (curVal == 3) {
       var editForm = $find("<%=RadGrid1.ClientID%>").get_masterTableView().get_editItems()[0].get_editFormItem();
     }
}

It appears that the $find call is what's disabling the popup. If I comment that out, the popup displays normally.

[Solved] Error when try to print the grid

Heey Guys

got a strange error when I'm trying to open the page where the grid is

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>). on line 18

`function` `PrintRadGrid(radGridId) {`

        `var` `radGrid = $find(radGridId);`

        `var` `previewWnd = window.open('about:blank',` `'',` `'',` `false);`

        `var` `sh =` `'<%= ClientScript.GetWebResourceUrl(UserGrid.GetType(),String.Format("Telerik.Web.UI.Skins.{0}.Grid.{0}.css",UserGrid.Skin)) %>';`

        `var` `styleStr =` `"<html><head><link href = '"` `+ sh +` `"' rel='stylesheet' type='text/css'></link></head>";`

        `var` `htmlcontent = styleStr +` `"<body>"` `+ radGrid.get_element().outerHTML +` `"</body></html>";`

        `previewWnd.document.open();`

        `previewWnd.document.write(htmlcontent);`

        `previewWnd.document.close();`

        `previewWnd.print();`

        `previewWnd.close();`

        `radGrid.get_masterTableView().fireCommand("EnablePaging",` `"");`

    `}`

thanks for help and fast answer !

[Solved] Yet another Grid FormTemplate client side problem

I recently posted a problem about disabling controls client-side within a RadGrid FormTemplate: http://www.telerik.com/community/forums/aspnet-ajax/input/unable-to-find-a-usable-method-for-enabling-disabling-a-textbox-in-a-formtemplate.aspx

That screen works. I can now control the enabling/disabling of RadTextBoxes using a function call from a checkbox.
Now I have a similar problem. I have a similar screen in which the FormTemplate has several RadComboBoxes and RadButtons.
What I want to do is enable/disable a RadComboBox and a RadButton depending on the value of another RadComboBox.

I've attached a function to a RadComboBox's OnClientSelectedIndexChanged event. I know the function is being called. I know I'm getting the correct value of the dropdown. I know I'm getting back handles from the $telerik.findElement calls. As far as I can tell from your documentation I'm using the correct enable/disable calls for a RadButton and RadComboBox.

But this time nothing works. The status of the controls is not changing. Here's the code.

function test(sender, args) {
    var editForm = $find("<%=RadGrid1.ClientID%>").get_masterTableView().get_editItems()[0].get_editFormItem();
    var btn = $telerik.findElement(editForm, "btnSave");
    var combo = $telerik.findElement(editForm, "ComboBox1");

var curVal = sender.get_value();

    // if the calling combo box has this value,
    // disable the other controls.
    if (curVal == 3) {
       btn.set_enabled(false);
       combo.disable();
    }
    // Otherwise, enable
    else {
       btn.set_enabled(true);
       combo.enable();
    }
}
