Hello!

I have some problems with validatng fields through radGrid/popup edit form. The fields to be validated are used in both 'Add' and 'Edit' popups, but validation works only in 'Add' form. Here is my approach. In ascx file:

<th>Amount:</th>

<td><asp:TextBox ID="txtAmount" runat="server" />

<asp:CustomValidator ID="ResourceValidator2" runat="server" Display="dynamic" ValidateEmptyText="true"

ControlToValidate="txtAmount"

ErrorMessage="Amount has to be entered and it has to be numeric value. "

OnServerValidate="Validate_RealizationAmount" />

</td>

And on cs file the validation function:

protected void Validate_RealizationAmount(object source, ServerValidateEventArgs args)

{

double priceNum;

if (txtAmount.Text == "" ||

!double.TryParse(txtAmount.Text.Trim(), out priceNum))

{

args.IsValid = false;

}

Aditionally the ascx file is build in a way that the same file defines edit and add forms so that fields used in both are the same. So basically the submit is done by following button definitions:

<asp:LinkButton ID="btnUpdateEdited" runat="server" CommandName='<%# DataItem is Telerik.Web.UI.GridInsertionObject ? "PerformInsert" : "UpdateEdited" %>'>

<img style="border:0px;vertical-align:middle;" alt="" />

<%# DataItem is Telerik.Web.UI.GridInsertionObject ? "Add" : "Update"%>

</asp:LinkButton>

<asp:LinkButton ID="btnCancel" runat="server" CommandName="CancelAll">

<img style="border:0px;vertical-align:middle;" alt=""/>Peruuta

</asp:LinkButton>

So, basically when using the 'Add' popup the system prints an error text if the field is not valid, but doesn't do the same when using 'Edit'. I don't know where to start digging. Help on this would be much appreciated.

[Solved] Own ContentAreaCssFile + Standard Css-File

Hi,

I'm using an own css file like this:

ContentAreaCssFile="~/App_Themes/Content.css"

That's all OK. But now, table borders (dotted borders for non-vosible table borders) aren't shown during editing and this is a real problem.
How can I use own style and the standard RadEditor styles for showing table borders ...

Do I need to refernce standard radeditor css file?

Please give me a little hint. It's urgent.

Kind regards!

IEnumerable Binding can not fire Add New Record

Hi,

I'm getting frustrated using Telerik RadGrid, i just create a simple page with

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">

<telerik:RadGrid ID="rg" runat="server" AutoGenerateColumns="false"
OnNeedDataSource="TestNeedDataSource">

<MasterTableView CommandItemDisplay="Top" InsertItemPageIndexAction="ShowItemOnCurrentPage"

EditMode="PopUp" >

<Columns>

<telerik:GridBoundColumn DataField="Id" />

<telerik:GridBoundColumn DataField="Name" />

</Columns>

<EditFormSettings PopUpSettings-Modal="true" PopUpSettings-Width="600"

PopUpSettings-ScrollBars="Auto" PopUpSettings-Height="600"

EditFormType="Template" >

<FormTemplate>

<table>

<tr>

<td>Test</td>

</tr>

</table>

</FormTemplate>

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

</telerik:RadAjaxPanel>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" />

And my code behind :

public IEnumerable<IDictionary> GenerateData()

{

for (var i = 0; i < 15; i++)

{

var dict = new Dictionary<string, object>();

dict["ID"] = Guid.NewGuid();

dict["Name"] = "Name_" + i;

yield return dict;

}

protected void TestNeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

rg.DataSource = GenerateData().ToDataSource();

}

Every time i click Add New Record, it call the ajax loading panel, but it doesn't open my popup modal. It does nothing.

Is there anything wrong with my code ? Or is it impossible to do this kind of binding with RadGrid ?

Thanks in advance

FilterTemplate with RadComboBox issue in Chrome and Firefox

Hello,

Please have a look at the following code:

<telerik:GridTemplateColumn HeaderText="Update" ItemStyle-Width="8%">

<FilterTemplate>

<div class="filter-wrapper">

<div>

<telerik:RadComboBox runat="server" ID="ddlUpdateFilter" AutoPostBack="true"

OnSelectedIndexChanged="ddlUpdateFilter_SelectedIndexChanged" MarkFirstMatch="true"

AllowCustomText="true" ShowToggleImage="false" Width="70px">

</telerik:RadComboBox>

<img src="../Resources/Common/filter.png" runat="server" id="imgUpdateFilter"

alt="filter" />

<asp:ImageButton runat="server" ID="imgClearUpdateFilter" ImageUrl="~/Resources/Common/clear-filter.gif"

CommandName="ClearFilter" />

</div>

</FilterTemplate>

<ItemTemplate>

<asp:CheckBox runat="server" ID="chkEdit" Enabled="false" />

</ItemTemplate>

</telerik:GridTemplateColumn>

I have a TemplateColumn in which I'm using FilterTemplate to apply filter on this column. The functionality is working fine in IE but when I open my page on Firefox or Chrome, all the columns having FilterTemplate become so wide that the grid blows off the page to the right. Once I write AllowFiltering="false" for that column, the column width comes back but obviously filtering is gone too.

A quick response in this regard will be highly appreciated.

Thanks.

Saving PageSize server side on change

Hi there,

I have a Rad Ajax Grid in which I'm dynamically adding pagesize values for the pagesize combobox.
When loading, I'm retrieving a user's preferred page size and applying this to the grid.
When the pagesize is changed I would like to save the new size to a database but I'm having a problem.

At the moment I know the PageSizeChanged event is being fired by showing an alert, but a function I'm calling to write the value back to the database doesn't seem to be called.
If I place an alert before and after my function they both fire. I know the function works because I'm using it elsewhere on the page (i.e. if there's not value set, I write a default etc).

Can anyone offer any suggestions as to why this is causing a problem?

Cheers
Rich

Problem with exporting from filtered grid

Hi,

I'm having problems exporting from a filtered gridcontrol. Whenever I apply a filter, it is applied perfectly on the webinterface, but exporting to .pdf format seems to ignore the filter, resulting in a full list of the datasource in the pdf file.

I've spent half a day reading through your forums, and tried every relevant course, without any luck. I've noticed that most of these, are not using OnNeedDataSource as datasource, could my problem be here?

I would be happy to supply code snippets, but as I have tried at least 10 different things with no success, I don't think my problem lies in the export itself.

I am not doing anything custom with the filtering, but it seems like the MasterTableView has forgotten its filtering, once the pdf event is fired. Should I be doing anything to ensure that the filter persists?

Any and all help would be much appreciated - and if you need additional info I'll supply it ASAP :)
