Hi,

When I try to use client side validation on RadMaskedTextbox as follows, the validation still takes place after a postback. is this a bug?

I try to follow your demo https://demos.telerik.com/aspnet-ajax/textbox/functionality/validation/defaultvb.aspx

     <asp:RequiredFieldValidator ErrorMessage="Mandatory" ValidationGroup="Contact" Enabled="True" id="batchReq" ControlToValidate="batch" CssClass="text-danger small" display="dynamic" runat=server />
    <br />

      <telerik:RadMaskedTextBox RenderMode="Lightweight" EnableEmbeddedSkins="false" Skin="MetroTouchNeutral" ValidationGroup="Contact" ID="rmt_tijd" visible="true" runat="server" Mask="<0..24>:<0..59>" Width="30%"></telerik:RadMaskedTextBox>

                            <asp:RequiredFieldValidator EnableClientScript="true" ErrorMessage="Mandatory" ValidationGroup="Contact" Enabled="true" InitialValue="00:00" id="RequiredFieldValidator3" ControlToValidate="rmt_tijd" CssClass="text-danger small" display="dynamic" runat=server />

Error with connecting to mdb is currently open by other user

Hi,

I'm using the following AccessDataSource

<asp:AccessDataSource ID="AccessDataSource2" runat="server"

EnableCaching="true"

CacheDuration="300"

DataFile="\\servername\myfile.mdb"

SelectCommand="SELECT `CustomerNo`, `Company`, `Attention`, `City`, `State` FROM `Customers`" >

</asp:AccessDataSource>

for

<telerik:RadComboBox ID="ddlCustomers" runat="server"

Width="150px" Height="150px"

Skin="Vista"

DataSourceID = "AccessDataSource2"

DataTextField = "CustomerNo"

DataValueField = "CustomerNo"

DropDownWidth="410px"

EmptyMessage="Select a Customer"

EnableItemCaching="true"

EnableLoadOnDemand="true"

EnableVirtualScrolling="true"

HighlightTemplatedItems="true"

SelectedValue='<%# DataBinder.Eval(Container, "DataItem.CustomerName") %>'

AllowCustomText="true"

OnSelectedIndexChanged="ddlCustomers_OnSelectedIndexChanged" AutoPostBack="True"

>

<HeaderTemplate>

<table style="width: 400px" cellspacing="0" cellpadding="0">

<tr>

<td style="width: 100px;"> Customer No</td>

<td style="width: 150px;">Company Name</td>

<td style="width: 150px;">City</td>

</tr>

<tr>

<td style="width: 100px;"></td>

<td style="width: 150px;">Attention</td>

<td style="width: 150px;">State</td>

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table style="width: 400px" cellspacing="0" cellpadding="0">

<tr>

<td style="width: 100px;"><%# DataBinder.Eval(Container.DataItem, "CustomerNo")%></td>

<td style="width: 150px;"><%# DataBinder.Eval(Container.DataItem, "Company")%></td>

<td style="width: 150px;"><%# DataBinder.Eval(Container.DataItem, "City")%></td>

</tr>

<tr>

<td style="width: 100px;"></td>

<td style="width: 150px;"><%# DataBinder.Eval(Container.DataItem, "Attention")%></td>

<td style="width: 150px;"><%# DataBinder.Eval(Container.DataItem, "State")%></td>

</tr>

</table>

</ItemTemplate>

</telerik:RadComboBox>

and if that Access file not open, then its fine otherwise I can received this error "Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Could not use ''; file already in use." I can open this Access file fine without any error when other is opening it.

Thanks

[Solved] Disable scrollbars in RadDock Programatically

Hoping someone's got the answer to this. It should be a one liner,but havent figured out how to do it or anywhere where it explains.

I'm creating raddock's programatically, having stored their states in the database. When i load them, the ContentTemplate is also set in code and is a User Control (ascx).

I've set

EnableEmbeddedSkins

="false"

I thought that might help me ovverride, but still missing the mark.

all I want is the horz and vert scrollbars to go away. Doesnt seem to matter if my zone is wider or smaller. with the same ascx it still always shows the scrollbars.

thanks!

Updating multiple items in listview updates only first item

[Solved] Display Finish on an Intermediate Page

Hi,

My wizard has 7 steps but after step 2, all other steps are optional. Rather than having the user click Next 6 more times, I'd like to show the Finish button on Step2. How do I go about this and How do you go about making tabs for optional steps (clickable) but not for the first 2 steps? The closest thread I found is this:

https://www.telerik.com/forums/display-next-previous-and-finish-button-in-all-radwizard-steps#SprpJ3GYo0Oy1IJxI8e_nw

but does not quite answer the question above.
