Questions on UI for ASP.NET AJAX Forum

Hello,

We are using RadControls for ASP.Net AJAX.

We have a RadGrid control set to "Auto-generate columns at runtime". The control also has filtering enabled. We have a vertical scrolling issue. The filter controls are anchored and do not scroll with the vertical scroll bar. This only occurs for filter controls that contain date and numeric values. The filter controls that contain string data scroll correctly with the vertical scroll bar.

The app has been deployed to IIS. We have two client machines that experience the above vertical scrolling issue. A third machine does not have any vertical scrolling issues.

All three machines are running IE9.

Any suggestions?

Thanks,
Mike

Simple call of Alert from RadMenuItem Click event handler

Hi - I'm new to the Visual Studio 2010 telerik asp.net Ajax tools from telerik.

-Visual Studio 2010 SP1 + Ajax Toolkit
-RadControls for ASP.NET Ajax, Version: 2012.2 607 (Jun 11, 2012)

I'm trying to follow the sample Navigation tutorial.

I build the project and page from scratch, following the nav tutorial. All was working as expected until I tried to replicate the Alert call.
At one point they add a RadAjaxManager, and add a RadMenuItem to a RadMenu, and in the RadMenu1_ItemClick event handler call :

RadAjaxManager1.Alert("The value for clicked item is: " + e.Item.Value);

The alert simply doesn't work for me. The page seems to refresh with no -popup alert.

I do understand javascript, and am used to having to register the script as the page loads.

So did I miss something in setting up the page, or some property of RadAjaxManager?
I've looked in other forum posts, but they don't seem to match my issue.

[Solved] GridNumericColumn Decimal Values changing to Scientific Notation

I'm using a RadGrid with a GridNumericColumn as:

<telerik:GridNumericColumn DataField="VALUE" HeaderText="Testing Decimal Value" DecimalDigits="6" DataType="System.Decimal" UniqueName="VALUE" NumericType="Number" />

When I enter a decimal value as 1.000015 it is accepted and I'm able to successfully process this value when accessing the hash table in my custom update command. However, when I try to enter a value with as 0.000015 or -0.000015 it turns into scientific notation (0.5E-05) when attempting to update the value and errors out. I have tried setting the AllowRounding to true or false as well as setting the KeepNotRoundedValue to true or false without any change. This problem only occurs if I use a value starting with a 0 and using more than 3 zeros in the precision, i.e. 0.00001.

I see in the Q1 2012 BETA there is a fix that may resolve my issue? (Fixed: RadNumericTextBox applies scientific notation on focus and wrong value on blur when DecimalDigits and AllowRounding are set and value like 0.0000001 is entered)

I'm unable to update to the BETA at this time and need to know if there is a possible workaround for this precision problem? Any help would be appreciated.

Thanks,
Brandon

UserControl Best CSS Implementation

I am building a Repository of user-control and wanted to find out the best way to server the CSS classes.

1. Should I load them ALL into 1 giant External CSS File and load it whenever a given user-control is rendered?
2. Should I load them into 1 External CSS File per user control?
3. Should I embed the CSS into the Markup of the user-control with RadCodeBlocks?

I cant see doing inline as a benefit as it would make a nightmare to modify an tweak.

This is open to all users to give me some pros and cons of each...

I'm leaning to #3 for manageability...

how to export programmatically without a webform control

Hey, I am trying to figure out if it is possible to construct a grid and use the export to excel functionality without using it in a webform. I just want to get the functional feature of exporting without visually displaying it in the web. Is that possible?

I know there is a TelerikData.dll that contains ExportToExcelML, so I'm looking for something like that, but probably in the ASP.NET version...

Thanks!

On second attemp item.UpdateValues(obj); do nothing

Anybody can help me?

{

case "Insert" :

try

{

TextBox txtComponente = (TextBox)e.Item.FindControl("txtComponente");

TextBox txtDescricaoComponente = (TextBox)e.Item.FindControl("txtDescricaoComponente");

Inserir(txtComponente.Text, txtDescricaoComponente.Text);

DisplayMessage(false, "Sucess!");

Response.Redirect("ConsultaComponente.aspx");

}

catch ( Exception ex)

{

DisplayMessage(true, ex.Message);

}

break;

case "Update" :

try

{

//First attempt

var ID = item.GetDataKeyValue("IdComponente").ToString();

TextBox txtComponente = (TextBox)e.Item.FindControl("txtComponente");

TextBox txtDescricaoComponente = (TextBox)e.Item.FindControl("txtDescricaoComponente");

Update(ID,txtComponente.Text, txtDescricaoComponente.Text);

//Second attempt

GridEditableItem item = e.Item as GridEditableItem;

var ID = item.GetDataKeyValue("IdComponente").ToString();

Componente obj = ComponenteController.Consulta(Convert.ToInt32(ID));

item.UpdateValues(obj);

Update(obj)

}

catch (Exception ex)

{

DisplayMessage(true, ex.Message);

}
