RadButton causing postback despite requiredfieldvalidator check

I'm using a RadButton inside a RadListView with ItemTemplate. The button is supposed to cause a post-back (handled by the ItemCommand of the RadListView) if a value in a RadTextBox is present, otherwise just display the RequiredFieldValidator/ValidationSummary info.

I've got it working to the point where it will validate the field (it pops the RequiredFieldValidator message as per the instructions in the ValidationSummary control), however regardless of whether or not the validator fires, it still does the postback and fires the ItemCommand handler.

html:

<telerik:RadListView ID="lstCommissions" runat="server"

DataKeyNames="EmployeeCommissionBankID"

ItemPlaceholderID="plhCommissions"

OnItemCommand="lstCommissions_ItemCommand"

OnItemDataBound="lstCommissions_ItemDataBound"

OnNeedDataSource="lstCommissions_NeedDataSource"

>

<LayoutTemplate>

<div class="CommissionControlContainer">

<div class="LoanNumberTitle">Loan Number</div>

<div class="CommissionTotalTitle">Commission</div>

<div class="SpreadTitle">Commission Spread</div>

<asp:PlaceHolder ID="plhCommissions" runat="server" />

</div>

</LayoutTemplate>

<ItemTemplate>

<div class="RowContainer">

<div class="LoanNumber"><asp:Label ID="lblLoanNumber" runat="server" /></div>

<div class="CommissionTotal"><asp:Label ID="lblCommissionTotal" runat="server" /></div>

<div class="SpreadButton">

<telerik:RadButton ID="btnSplit" runat="server"

AutoPostBack="true"

ButtonType="ToggleButton"

CausesValidation="true"

CommandName="Split"

CommandArgument='<% Bind("LoanNumber"); %>'

Style="padding-left: 25px;"

ToggleType="CheckBox"

>

<ToggleStates>

<telerik:RadButtonToggleState PrimaryIconCssClass="rbRemove" Text="Remove Spread" />

<telerik:RadButtonToggleState PrimaryIconCssClass="rbOk" Text="Spread" />

</ToggleStates>

</telerik:RadButton>

</div>

<div class="SpreadValue">

<telerik:RadNumericTextBox ID="txtSpreadAmount" runat="server"

AutoPostBack="true"

/>

<asp:RequiredFieldValidator ID="rfvSpreadAmount" runat="server"

ControlToValidate="txtSpreadAmount"

ErrorMessage="Spread amount is required"

Text="*"

/>

<asp:ValidationSummary ID="vsSpreadAmount" runat="server"

DisplayMode="BulletList"

ShowMessageBox="true"

ShowSummary="false"

Visible="true"

/>

</div>

</ItemTemplate>

</telerik:RadListView>

Just to verify to you that I'm setting the ValidationGroup for all controls involved (it is being set in code in the ItemDataBound handler):

if (e.Item is RadListViewDataItem)

{

RadListViewDataItem item = e.Item as RadListViewDataItem;

// item-level objects

Label lblLoanNumber = item.FindControl("lblLoanNumber") as Label;

Label lblCommissionTotal = item.FindControl("lblCommissionTotal") as Label;

RadNumericTextBox txtSpreadAmount = item.FindControl("txtSpreadAmount") as RadNumericTextBox;

RadButton btnSplit = item.FindControl("btnSplit") as RadButton;

RequiredFieldValidator rfvSpreadAmount = item.FindControl("rfvSpreadAmount") as RequiredFieldValidator;

ValidationSummary vsSpreadAmount = item.FindControl("vsSpreadAmount") as ValidationSummary;

EmployeeCommissionEntity ec = item.DataItem as EmployeeCommissionEntity;

if (ec.Amount.HasValue)

{

// set the validation groups for all the controls that need it

btnSplit.ValidationGroup =

txtSpreadAmount.ValidationGroup =

rfvSpreadAmount.ValidationGroup =

vsSpreadAmount.ValidationGroup =

"Split_" + ec.EmployeeCommissionBankID.ToString().Replace("-", string.Empty);

lblLoanNumber.Text = ec.LoanNumber;

lblCommissionTotal.Text = string.Format("{0:c}", ec.Amount);

txtSpreadAmount.MaxValue = ec.Amount.Value.ToDouble();

txtSpreadAmount.MinValue = 0;

}

else

item.Visible = false;

}

Any ideas? I'm going to handle this server-side (I'll test the text box and if it's blank I'll set the toggle of the button back to unchecked) but I'd really like the standard asp controls to handle it so no post-back happens unless it needs to.

Thanks

Calling javascript in edit mode from a web content form

I have a master page and a derived web content form using the specified master page. Any javascript I place in my Content1 and the body of the page goes in Content2. The issue is that I am calling a javacript but since the controls only exist in the Edit Mode of the RadGrid, when the page loads it is firing an error stating that the controls do not exist in the context.

Javascript

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

<script type="text/javascript">

function copyAmount() {

if (document.getElementById("<%=tbApprovedAmount.ClientID%>")) {

document.getElementById("<%=tbApprovedAmount.ClientID%>").value = document.getElementById("<%=tbRequestedAmount.ClientID%>").value;

}

</script>

</asp:Content>

Aspx

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

.

<EditFormSettings EditFormType="Template" FormStyle-BackColor="#DBE9FD">

<EditColumn UniqueName="EditCommandColumn1">

</EditColumn>

<FormStyle BackColor="#DBE9FD" />

<FormTemplate>

<table width="800px" border="0" >

<tr>

<td align="left">

<asp:TextBox ID="tbRequestedAmount" runat="server"

Text='<%# Bind("RequestedAmount", "{0:0.00}") %>' ></asp:TextBox>

<asp:RequiredFieldValidator ID="rfvRequestedAmount" runat="server" ErrorMessage="Requested amount is a required field"

Display="None" ControlToValidate="tbRequestedAmount" ValidationGroup="Service"></asp:RequiredFieldValidator>

<asp:Button ID="tbCopy" runat="server" Text="->" Height="20px"

OnClientClick="copyAmount" />

</td>

</tr>

</table

</FormTemplate>

</EditFormSettings>

Telerik Grid, GridClientSelectColumn bind data

Hi Telerik Team,

I am working on the Telerik Grid, my first column in that grid is "GridClientSelectColumn", with which I am able to 'check' the required row and save to the database, but I could not bind the saved items to that "GridClientSelectColumn". Below is the sample code which I am using.

1. In Aspx Page

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="true"

AllowAutomaticUpdates="True" PageSize="10" Width="100%" AutoGenerateColumns="false"

AllowMultiRowSelection="true" DataSourceID="sds_Reconcile" onitemcreated="RadGrid1_ItemCreated"

OnItemDataBound="RadGrid1_ItemDataBound" OnPreRender="RadGrid1_PreRender">

<telerik:GridClientSelectColumn DataTextField="pvkey" Text="select" UniqueName="column1"

HeaderText="Select"> </telerik:GridClientSelectColumn>
...
</Columns>
2. C# Code
a. In ItemDataBound and ItemCreated i have used this code

if (e.Item is GridDataItem) {

GridDataItem item = (GridDataItem)e.Item;

if (item.OwnerTableView.Name == "Table") {

if (item["is_recon"].Text == "True") {

CheckBox chkbx = (CheckBox)item["column1"].Controls[0];

chkbx.Checked =

true;

e.Item.BackColor = System.Drawing.

ColorTranslator.FromHtml("green"); }}}

b. In PreRender, I am using this code

foreach

(GridDataItem dataItem in this.RadGrid1.MasterTableView.Items)

{

if (dataItem["is_recon"].Text == "True")

{

CheckBox chkbx = (CheckBox)dataItem["column1"].Controls[0];

chkbx.Checked =

true;

}

dataItem["column1"].BackColor = System.Drawing.Color.Gray;

}

I am able to get the correct values from the database, and they are executing with the chkbx.Checked = true. But I could not see the items checked in the webpage when they are loaded.

And also I am using Default skin, and assigning my custom css to that Grid, with which I am unable to color the row. (dataItem["column1"].BackColor = System.Drawing.Color.Gray;)

Thanks
Mark

[Solved] Download File in Content Page

Dear developers hello,

I use RadExplorer, in my classic website, with the option to download (or open) files with double click. It works great.

Now i changed my pages and i use Master and Content pages, instead of classic.
RadExplorer is in the Content Page of a Master Page.
After that change, the download is not working. I double click the file and it does nothing (download or open).
The file Handler.ashx is the same.

I use:
Visual Studio 2008 v9.0.30729.1 SP (ASP.NET Visual Basic)

RadControls for ASP.NET Ajax 2010.2.929.35 Trial

Windows 7

If you need any other information, please let me know.
Thank you in advance for your time.

Disable others appointment

Hi,
I am developing telerik Radscheduler in which there are multiple users who login into the scheduler.
I want to design the system in a way where one user can only insert or delete only his appointment and cannot touch other's appointment. He/she should be disabled from touching others appointments...How do I do that?
Code snippet would be appreciated.
