Uncaught Error: Unexpected ajax response was received from the server.
This may be caused by one of the following reasons:

- Server.Transfer.
- Custom http handler.
- Incorrect loading of an "Ajaxified" user control.

Verify that you don't get a server-side exception or any other undesired behavior, by setting the EnableAJAX property to false.

how to use only integer values for NumericTextBox

Hi, I'm using in asp.net a NumericTextBox control, with a lower and upper limit value, but I don't know how to set that only integers are displayed, it seems that the limits and the maximum number of digits equal to 4 allow to limit the damage inserting years, but the '.' is displayed to separate the thousands

How do I avoid it? Thank you

        </Columns>
    </MasterTableView>
</telerik:RadGrid>

In RadGridEntries_BatchEditCommand I'm capturing the old and new values:

Hashtable newValues = command.NewValues;
Hashtable oldValues = command.OldValues;

But the Percentage template column is missing from OldValues:

The Percentage column is stored as a decimal(6,3). I'm trying to display the value with the 3 d.p and a % sign. It's not stored as a percentage i.e. if the value is stored as 10.505 then it is displayed as 10.505 - I'm not storing it divided by 100.

I'm using the Command Item buttons to Save and Insert.

What can I do to make sure that the Percentage Old Value is stored so that I can compare it to the New Value?

Kind regards,

Richard

Changing the visible property server side not working

I have a RadNumericTextbox where the visible field is set to false. Depending on another variables value, the RadNumericTextbox visible may change to true. This is not working. The field is in a panel.

I stepped through the code and the visible property will not change.

I even directly changed the value to true and the value remained false in the watch list.

Radnumerictextbox initialize max value

Good morning,

i have page where top consist of a form and bottom consist of grid data. Grid data has 4 types of record:

'S' - saved record where when i click on the row in the grid top of the page is fill out and I may modify radnumerictextbox and set the max value of radnumerictexbox in code behind

'P' - pending record where when i click on the row in the grid top of the page is fill out and I cannot modify radnumerictextbox however the requested hours which i get from SP into the grid has to go to radnumericbox instead max value is going into box.

For example: from 'S' saved record i set max value to 100. After that when i click on ''P' record instead of going 200 hours(from SP) into radnumeric box it will show max value from 'S' saved record which is 100.

My question is: is there possibilty to initialize max value when i click on 'P' record to show me actually reguested hours instead of max value set manually from previous clicked even though requested hours is greater than max value. if not then what other option do i have?

Thanks so much for your help.

Vitaly.

RadNumericTextBox layout issues after upgrade

I'm upgrading Telerik UI for ASP.NET AJAX from a very old version, from 2013, to the latest. For the most part it has been plug & play except for RadNumericTextBox, which doesn't display the spin buttons correctly and doesn't show the validation icon correctly.

Here is a screenshot of old vs new:

This is the markup:

<table>
	<tr id="trPassExp" runat="server" class="lhqDetailLabel">
		<td colspan="2" align="right">Password expires every&nbsp;</td>
		<td colspan="2" style="text-align: left;">
			<telerik:RadNumericTextBox runat="server" 
				RenderMode="Lightweight"
				ShowSpinButtons="true" 
				NumberFormat-DecimalDigits="0" 
				Width="60px"
				EnableEmbeddedSkins="True" 
				Skin="Sunset" 
				MinValue="7" 
				MaxValue="90" id="txtPassExpires"></telerik:RadNumericTextBox>&nbsp;days&nbsp;&nbsp;
		</td>
	</tr>
	<tr id="trPassLen" runat="server" class="lhqDetailLabel">

		<td colspan="2" style="text-align: left;">

			   Skin="Sunset"

NumericTextBox rounding incorrectly

The RadNumericTextBox is rounding incorrectly after a postback.

I am currently using 5 decimal places with the value of

0.00481487920209807

When the page loads it displays correctly

After I click the Postback button the display value changes

<div class="form-row">
            <asp:Button ID="btnCausePostback" Text="Postback" runat="server" OnClick="btnCausePostback_Click" />
            <telerik:RadNumericTextBox runat="server" ID="txtUnitCost" NumberFormat-DecimalDigits="5" Value="0.00481487920209807" />
        </div>

protected void btnCausePostback_Click(object sender, EventArgs e)
        {

        }

I am not sure what the round function is doing in this scenario?

I do have a work around which is setting

NumberFormat-AllowRounding="false"

And doing my own rounding using Math.Round to set the value properly.

Currently using Q2 2021 Telerik version
