RadCombo loses its selection and data when the form submits

Hi,

I have 2 combo boxes on a page. The second one is dependent on the data selected in the first. The first one is loaded on page load.

Everything works fine till this step.

1. User comes to screen, selects data in 1st combo.

2. 2nd combo gets populated. User selects data in 2nd combo.

Now here I have autopostback=true, and OnSelectedIndexChanged="RadComboBox2_SelectedIndexChanged", which hits the server and populates a Grid control.

The problem I am facing is that when the form comes back, I have lost the data and the selected value in the 2nd dropdown. As a result, the grid control also doesnt get any data.

This is how the 2nd combo looks.

                            <telerik:RadComboBox style="margin-left: 77%" ID="RadComboBox2" runat="server"          
                      Skin="Windows7" OnClientItemsRequested="ItemsLoaded"         
                      OnClientSelectedIndexChanging="LoadFunds" OnSelectedIndexChanged="RadComboBox2_SelectedIndexChanged"         
                      OnItemsRequested="RadComboBox2_ItemsRequested" Width="350px" AutoPostBack="true">         
                    </telerik:RadComboBox>         
                     

Any help would be appreciated here.

Thanks.

Add custom class to RadTextbox when validates fails

Hi,

I have following issue, i used this approach on previous project. Now with telerik components I dont get effect of higlighted control. Jquery add class to control wich is below that visible one.

                    <span id="ctl00_ctl00_BodyBase_ContentPlaceHolder1_DocTitle_wrapper" class="RadInput RadInput_Default" style="white-space: nowrap;"><input size="20" id="ctl00_ctl00_BodyBase_ContentPlaceHolder1_DocTitle_text" name="ctl00_ctl00_BodyBase_ContentPlaceHolder1_DocTitle_text" class="riTextBox riEnabled" style="width: 90%;" type="text"><input id="ctl00_ctl00_BodyBase_ContentPlaceHolder1_DocTitle" name="ctl00$ctl00$BodyBase$ContentPlaceHolder1$DocTitle" class="rdfd_ inputError" style="border: 0pt none ; margin: -18px 0pt 0pt; padding: 0pt; overflow: hidden; visibility: hidden; width: 1px; height: 1px;" value="" type="text"><input autocomplete="off" id="ctl00_ctl00_BodyBase_ContentPlaceHolder1_DocTitle_ClientState" name="ctl00_ctl00_BodyBase_ContentPlaceHolder1_DocTitle_ClientState" type="hidden"></span>         
                             
                    <span id="ctl00_ctl00_BodyBase_ContentPlaceHolder1_RequiredFieldValidator1" class="validation-error" style="color: Red; visibility: visible;">&nbsp;</span>

Its class inputError on second input, but i think i need it on first one.

Can you help me to set up css class to input control wich is handled by telerik RadTextbox/RadFormDecorator?

Mainly i want show validation summary with listed errors and highlight conflicted controls. Is there some way to do it, when im using RadTextBox/RadFormDecorator?

Please as small more code as possible. I have many places to edit. Best solution is change Jquery script to add error class to the right input for me.

Many Thanks!

[Solved] Grouping shows time along with Date

I have a GridTemplateColumn in a RadGrid. It was a DateTime Column.

    
            <telerik:GridTemplateColumn FilterListOptions="VaryByDataType" DataType="System.DateTime" 
        
                                DataField="cr_task_dt" GroupByExpression="cr_task_dt Group By cr_task_dt" HeaderText="Next date to contact" 
        
                                UniqueName="cr_task_dt" SortExpression="cr_task_dt"> 
        
                                <ItemTemplate> 
        
                                    <asp:Label runat="server" ID="lblTaskDate" Text='<%# Eval("cr_task_dt_str") %>'></asp:Label> 
        
                                </ItemTemplate> 
        
                                <EditItemTemplate> 
        
                                    <asp:TextBox CssClass="datepicker" ID="txtTaskDate" Text='<%# Eval("cr_task_dt") %>' 
        
                                        runat="server"></asp:TextBox> 
        
                                    <ajax:MaskedEditExtender ID="MaskedEditExtender4645" runat="server" TargetControlID="txtTaskDate" 
        
                                        Mask="99/99/9999" MessageValidatorTip="true" OnFocusCssClass="MaskedEditFocus" 
        
                                        OnInvalidCssClass="MaskedEditError" MaskType="Date" DisplayMoney="Left" AcceptNegative="Left" 
        
                                        CultureName="zh-SG" ErrorTooltipEnabled="True" /> 
        
                                </EditItemTemplate> 
        
                            </telerik:GridTemplateColumn>

The grid datasource was a linqdatasource. It works fine in all functionalities like sorting,filtering and grouping.
The only issue is it shows Time part in the grouping header as below,

"Next date to conact: 6/1/2010 12:00:00 AM"

"Next date to conact: 4/12/2010 12:00:00 AM"

I dont want the Time part (12:00:00 AM) to be displayed in the group header. How to remove it?

Please help me sort it out. Thanks in advance.

Regards,

Aswin Suriya

AJAX RadControls total Newbie Question

Hi All,

We are currently in the process of purchasing the AJAX RadControls suite for 3 developers. My question is, how easy is it / how fast can one get up to speed on developing with the AJAX controls assuming the following:

1. Everyone in our team is completely new to AJAX and working with RadControls

2. we have been supporting an old solution that uses RadControls but all of the templates were built for us by a consultant

3. the solution we currently support is .Net 1.1 and we develop in VS2003

4. We will be building our new app on VS2005 and .Net 2.0

We need to get a fairly small searching and customer database management app built in a month. We have done the functional and tech specs and are ready to begin coding.

So my question is (finally) - Is it realistic to expect us to be able to get up to speed and build some telerik enabled pages inside a month?

Where would you suggest we start? I downloaded the 794 page manual from the telerik site and will read but obviously that is going to eat a bunch of time. Are there any other good quick resources to get us up and running quickly?

Appreciate any feedback even if it is just - "you're screwed man..." :)

OnItemCommand only returning RowClick

Sorry if I've missed the point here, but here's my issue.

I've got a RadGrid declared like this

<telerik:RadGrid ID="RadGrid1" GridLines="None" runat="server" AllowPaging="True"

AutoGenerateColumns="False" OnUpdateCommand="UpdateItem" OnInsertCommand="UpdateItem"

AutoGenerateDeleteColumn="false" AutoGenerateEditColumn="false" OnDeleteCommand="DeleteItem"

Skin="WebBlue" OnNeedDataSource="NeedDataSource" Width="50%" OnItemCommand="LawyerSelected">

<MasterTableView CommandItemDisplay="TopAndBottom" AutoGenerateColumns="false" DataKeyNames="LawyerID"

BorderColor="Black" BorderWidth="1px" GridLines="Both">

<telerik:GridBoundColumn DataField="LawyerID" DataType="System.Guid" AllowFiltering="false"

HeaderText="LawyerID" UniqueName="LawyerID" Visible="False">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Company" HeaderText="Company" UniqueName="Company">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn UniqueName="TemplateColumn2">

<asp:LinkButton ID="EditButton" CommandName="Edit" CommandArgument="Edit" Text="Edit" runat="server"></asp:LinkButton>

</ItemTemplate>

<asp:LinkButton ID="UpdateButton" CommandName="Update" CommandArgument="Update" Text="Update" runat="server"></asp:LinkButton>

<asp:LinkButton ID="CancelButton" CommandName="Cancel" CommandArgument="Cancel" Text="Cancel" runat="server"></asp:LinkButton>

</EditItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

The important bits being that the auto edit feature is turned off.

What I want to be able to do is either click on the edit link (Edit Button) to edit the row or click on a row to do something else (display related information).

For some reason when I click on a row the CommandName that’s returned is usually rowClick and not Edit.

RadMenuItem icons via CSS?

Is there any way to generate the menu item icons (the image icons associated with each menu item) with CSS instead of using the ImageUrl property?

With this release the number of resources (images, css, etc.) in my pages have dropped dramatically, which is great, but I still have a bunch of individual images coming down to support my menus and context menus.

I'd like to use CSS sprites and have all of these images in a single file, but haven't been able to figure out a way to achieve this. The RadMenuItem does have a CssClass property, but that controls the CSS class of the entire item, not the 'img' tag (I forget whether it is applied to the 'li' or the 'a' tag).

It would be great if it had a property like 'ImageCSSClass' that when set, adds an additional class to the img tag, so it would look something like this:

<img class="rmLeftImage MyCutIconCssClass" alt="" />

I could then assign a background image to that CSS class and assign the appropriate coordinates from my image sprite.

[Solved] IE8 problem: The node text is fully displayed in narrow treeviews on mouse hover

Hello,

I am testing our website with IE8 and noticed some strange behavior with Telerik TreeView component. Some treeviews we use in our website are narrow in width and long in height, thus vertical and horizontal scrollbars are displayed. With IE8, when the user hovers on a node with a long text, the whole text is displayed over the page. Any solution?

Ajax Rebind Grids Size problem inside Tab

My page contains 2 tabs and under each tab, there is a grid inside.

After performing something on the page, it fires a ajax request to the server side to cause a rebind to the grid.
The grid inside the focused tab is rendered perfectly. However the second one is not, the height of the grid is just about 1 row.

javascript:

    
                    function ReloadGrid()  
        
                    {                           
        
                        $find("<%=RadAjaxManager1.ClientID%>").ajaxRequest("RefreshGrid");                          
        
                     }

Declaration:

    
            <telerik:RadTabStrip ID="radGrid" SelectedIndex="0" runat="server" MultiPageID="GridMultiPage" Skin="Outlook">

Below code is for code behind:

protected void gviewProjectwisetask_ItemCommand(object source, GridCommandEventArgs e)

{

try

{

if

(e.CommandName.ToUpper() == "SELECT2")

{

GridDataItem gvr = (GridDataItem)((LinkButton)e.CommandSource).NamingContainer;

int RowIndex = gvr.ItemIndex;

if (RowIndex > -1)

{

int FileId = Convert.ToInt32(gviewProjectwisetask.MasterTableView.Items[RowIndex].Cells[12].Text);

string Str = FileId.ToString();

Response.Redirect(

"DownloadRedirect.aspx?ID=" + FileId);

}

catch (Exception ex)

{

}

}

Actual problem is when i click on linkbutton in gridview for downloading the file then progressbar showing perfectly here i have used Response.Redirect("DownloadRedirect.aspx?ID=" + FileId); after this line it is going to catch block here i want a solutions is that in catch block i want to disable the progressbar means i want to present aspx form in normal mode means without progressbar.

Just suggest me how it is possible.
