View State Errors with Sample / Rad Dock

Hello there,

using a sample provided in the following link (http://www.telerik.com/community/forums/aspnet-ajax/docking/dynamic-creation-of-layout-zones-and-docks.aspx) and even in my own code I get viewstate errors ("...The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. ...") when I do the following:

In the example provided:

Add a new tab by click create new page.
Add a dock to the first tab.
Go to the second tab.
Add a dock to the second tab.
Go Back to the first tab. BOOM! View state error.

Does anyone know a solution for this? My project is bascially structured exactly like this sample except I use a database.

Thanks,

Brian

RadGrid Height set to 300px by default

After submitting this request, I kept searching your knowledge base, forums, etc. and found a solution to my problem -- turning off the auto scroll setting. What an idiot I am!

You may close this item now. I'm a happy camper. My apologies for mucking up the works with this one!

I have a RadGrid that I need to grow vertically with content. If I do not set a height, it always defaults to 300px. I have attached or included several items for you to review. Using the IE Developer Tools, I have turned off the default 300px height setting and the grid behaves exactly the way I want it to.

First the definition of the grid:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" EnableEmbeddedSkins="true" Skin="Default" ShowHeader="false"

AllowPaging="True" PageSize="5" GridLines="Horizontal" >

<PagerStyle Mode="NextPrevAndNumeric" />

<MasterTableView >

<Columns>

<telerik:GridTemplateColumn UniqueName="TemplateColumn1" >

<ItemTemplate>

<table width="155px">

<tr>

<td >

<asp:Image ID="Image1" Style="float: left;" Width="150px" Height="100px" ImageUrl='<%# Eval("PicturePath")%>'

BorderWidth="1px" runat="server" AlternateText="Stock Image" />

</td>

</tr>

</table>

</ItemTemplate>

<ItemStyle HorizontalAlign="Center" />

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="TemplateColumn2" >

<ItemTemplate>

<table>

<tr>

<td>

<div>

<ul>

<li>

<label><b>Address: </b></label><%# Eval("ListingStreetAddress")%>

</li>

<li>

<label><b>Beds: </b></label><%# Eval("Bedrooms")%>

</li>

<li>

<label><b>Baths: </b></label><%# Eval("Bathrooms")%>

</li>

<li>

<label><b>Price: </b></label><%# Eval("ListingPrice", "{0:##,##0.00}")%>

</li>

<li>

<label><b>City: </b></label><%# Eval("CityName")%>

</li>

<li>

<label><b>State: </b></label><%# Eval("StateName")%>

</li>

<li>

<label><b>Country: </b></label><%# Eval("CountryName")%>

</li>

</ul>

</div>

</td>

</tr>

</table>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn UniqueName="Lat1" DataField="Lat1" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="Long1" DataField="Long1" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="TblName" DataField="TblName" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="ListingStreetAddress" DataField="ListingStreetAddress" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="CityName" DataField="CityName" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="StateName" DataField="StateName" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="CountryName" DataField="CountryName" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="ListingPlannedCommName" DataField="ListingPlannedCommName" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="ListingSubdivision" DataField="ListingSubdivision" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="ListingZipPostalCode" DataField="ListingZipPostalCode" Visible="false"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings AllowDragToGroup="false">

<Scrolling AllowScroll="true" UseStaticHeaders="false" />

</ClientSettings>

</telerik:RadGrid>

Attachments:
(1) I have attached a screen capture of the grid as it displays with default settings as grid_height_issue_1.png .

(2) I have attached a screen capture of the IE Developer Tools window where I have disabled the default height setting as grid_height_issue_2.png .

(3) I have attached a screen capture of the grid as it displays after disabling the default height setting as grid_height_issue_3.png.

Your help in the best manner of turning off this 300px height setting would be most appreciated.

Thanks!

Radgrid, Grouping and Context Menu

For some reason I am having a problem with a Radgrid's Context Menu when only some of the groups are expanded in a radgrid.

The Grid is grouped using an expression. And when all groups are expanded a right click fires the Context Menu.

However if any of the groups are collapsed the event does not fire and the normal browser right click menu appears. If I then expand the collapsed item the context menu re appears on right click.

Any ideas?

Cheers

RadFilter will not keep it's state between postbacks

<%@ Control Language="VB" AutoEventWireup="true" CodeFile="SegmentationCreator.ascx.vb" Debug="true"

Inherits="Controls_SegmentationCreator" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

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

<telerik:RadFilter ID="RadFilter1" runat="server"

CssClass="RadFilter RadFilter_Default" ExpressionPreviewPosition="Bottom" ShowApplyButton="false" AllowFilterOnBlur="true">

<FieldEditors>

<telerik:RadFilterTextFieldEditor DisplayName="text1" FieldName="textfield" TextBoxWidth="120" />

<telerik:RadFilterNumericFieldEditor DisplayName="number1" FieldName="numberField" />

<telerik:RadFilterBooleanFieldEditor DataType="System.Boolean" DisplayName="check1" FieldName="bitField" />

<telerik:RadFilterDateFieldEditor DataType="System.DateTime" DisplayName="date1" FieldName="dateField" />

</FieldEditors>

</telerik:RadFilter>

<ul>

<telerik:RadListView ID="RadListView1" runat="server" DataSourceID="sqlData1">

<ItemTemplate>

<li><%# Eval("text1")%></li>

</ItemTemplate>

</telerik:RadListView>

</ul>

<asp:SqlDataSource ID="sqlData1" runat="server"

ConnectionString="<%$ ConnectionStrings:FEI%>" SelectCommand="SELECT TOP 10 Email.email as text1, 1 as number1, 0 as check1, GETDATE() as date1 FROM Email">

</asp:SqlDataSource>

<asp:HiddenField id="hiddenQueryText" runat="server" />

</telerik:RadAjaxPanel>

Every time I click on add field or anything it just reverts to the first-time load state. There is nothing in the code-behind file. The only other odd thing is that If I add the RadScriptManager to the the ascx, the page gives an error that "Only one instance of a ScriptManager can be added to the page." This control above is being added to the page using Page.LoadControl("path/nameof.ascx") so I don't really have control over that part.

RadCaptcha audio on chrome

Hello Everyone,

We are using radcaptcha for validating purpose. I have come across a weird problem with audio link button of captcha control.

Audio link button working fine on IE and firefox, but we are not able to play the ImageText multiple time on chrome. It works for the first click, but if we click multiple times on audio link button, its not playing Image Text.

I might need to enable some property for captcha control that i am not aware of.

Does any one have any suggestions??

<telerik:RadCaptcha ID="radCaptcha" Runat="server" EnableRefreshImage="true" CaptchaImage-EnableCaptchaAudio="true" CaptchaImage-UseAudioFiles="true" ErrorMessage="You have entered an invalid code." ValidationGroup="Summary" forecolor="#660000" Display="Dynamic" CaptchaLinkButtonText="Generate New Image<br/>" EnableEmbeddedScripts="True" EnableViewState="True" CaptchaImage-AudioFilesPath="~/App_Data/RadCaptcha" ImageStorageLocation="Cache" ViewStateMode="Enabled">
</telerik:RadCaptcha>

RadGrid client side CheckAll for multiple dynamic columns

Hello,

I'm using RadGrid Q1 2011 (2011.1.519.40) with several bound columns and then dynamically added check box columns that I add at run time and set in RadGrid1_ItemCreated on bind. These are templated columns with checkbox headers and the columns using the typical:

GridTemplateColumn templateColumn = new GridTemplateColumn();

templateColumn.HeaderTemplate = new MyHeaderTemplate(sHeader, i);

templateColumn.HeaderText = sHeader;

templateColumn.ItemTemplate = new MyCheckboxTemplate(sHeader, i);

this.RadGrid1.Columns.Add(templateColumn);

inside of a loop. The classes are typical InstantiateIn classes only the header has a label with a date. The checkbox template is just that, a checkbox in every column of every row.

For reference:

public MyCheckboxTemplate(string cName, int j)

{

colname = cName;

index = j;

}

public void InstantiateIn(System.Web.UI.Control container)

{

CheckBox cb = new CheckBox();

cb.ID = colname + "_" + index;

cb.Visible = true;

cb.Enabled = true;

container.Controls.Add(cb);

}

MyHeaderTemplate :

public MyHeaderTemplate(string cName, int j)

{

colname = cName;

index = j;

}

public void InstantiateIn(System.Web.UI.Control container)

{

Label lblHeader = new Label();

lblHeader.ID = colname;

lblHeader.Text = colname;

CheckBox cb = new CheckBox();

cb.Attributes.Add("onClick", "CheckAll(event);");

cb.ID = colname + "_" + index;

cb.Visible = true;

cb.Enabled = true;

container.Controls.Add(cb);

container.Controls.Add(lblHeader);

}

I've been banging my head trying to create a straight forward CheckAll client side javascript that will detect which header was clicked and check all the checkboxes in that column if they aren't checked and vice versa. I've found many examples of how to do this with static columns but can't quite seem to get the JS correct for dynamic columns. There could be anywhere between 1-180.

Thanks in advance for any help!
