I am doing all my Grid Building using Server-Side code (class I created) because it's dynamic.

I created a class implementing ITemplate. In this class I create a single Label control within the InstantiateIn() method and I add it to the controls array.

When the grid loads, it shows all the parent rows, and it show the ">" button on the left of each row to expand and view it's details. However, when I click the ">" button, the grid refreshes and all the ">" buttons vanish. The nested rows seem to have all dissapeared. I am assuming there is an event that runs when the ">" button is clicked, and somehow because my grid is dynamic, I lose the detail rows. Anyone know what event I might be overlooking on the click of ">" to fix me problem?

Message on Delete

In my RadGrid, Autogeneratecolumns = true,
<
<Columns>
                   <telerik:GridEditCommandColumn UniqueName="EditCommandColumn" ButtonType="ImageButton" EditImageUrl="../Images/Edit.png" ></telerik:GridEditCommandColumn>
                    <telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="DeleteColumn" ButtonType="ImageButton" ImageUrl="../Images/Delete.png"></telerik:GridButtonColumn>
                </Columns>
>

How do I display a message when Delete button is clicked, as 'OnClientClick' is not a valid event for GridButtonColumn ?

Binding RadComboBox to RadGrid

I am adding a RadComboBox to the EditItemTemplate of a RadGrid. When I add SelectedValue='<%# Bind("RegistryValue") %>' to the RadComboBox tag (see first section of code below) I get an "Argument Out Of Range Exception" when I rebind the RadGrid (see second section of code). If I remove the SelectedValue attribute it works, but the original value is in the RadComboBox when I read it. I think I am missing something before the RadGrid1.Rebind() command, but I don't know what.

Adding SelectedValue='<%# Bind("RegistryValue") %>' to the RadComboBox tag caused the problem.

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn DataField="RegistryValue" FilterControlAltText="Filter RegistryValue column" HeaderText="RegistryValue" SortExpression="RegistryValue" UniqueName="RegistryValue">

<EditItemTemplate>

<telerik:RadComboBox ID="RadComboBox1" Runat="server" DataSourceID="RegistryValueSqlDataSource" DataTextField="RegValueListValue" DataValueField="RegValueListID" SelectedValue='<%# Bind("RegistryValue") %>'>

</telerik:RadComboBox>

</EditItemTemplate>

<ItemTemplate>

<asp:Label ID="RegistryValueLabel" runat="server" Text='<%# Eval("RegistryValue") %>'></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

When RadGrid1.Rebind() is called I get an Argument Out Of Range Exception error.



protected

void EditRadButton_Click(object sender, EventArgs e)

{

foreach (GridItem item in RadGrid1.MasterTableView.Items)

{

if (item is GridEditableItem)

{

GridEditableItem editableItem = item as GridDataItem;

editableItem.Edit = true;

}

RadGrid1.Rebind();

}

How to display different type of images in ad rotator in aspx page

I have an Ad Rotator and the File contents are coming from a table column, the problem is sometime the File columns contents are image, sometimes text file or the column is empty. My question is how do I display a static image when there are no attachment images or the attachment is there but it's not an image, its a .txt file or .doc file.

<telerik:RadRotator ID="rrotAttachmentImages" runat="server"                                                      
  RotatorType="CoverFlowButtons"
Height="250px" Width="700px"
    ItemHeight="225px" ItemWidth="700px"                                                   
 ScrollDuration="100" >
 <ItemTemplate>
      &nbsp;&nbsp;&nbsp;&nbsp;                                                  
 <asp:CheckBox ID="chkImageDefault" runat="server" 
  Text="Default Image" Visible='<%# Eval("Default").ToString() == "1" %>'></asp:CheckBox>                                                  
 <asp:Label ID="lblImages_Comments" runat="server" Text="Comments:"></asp:Label>
<telerik:RadTextBox ID="rtxtImageComments" runat="server" Width="300px" Text='<%# Eval("Comments") %>' Enabled="false" ></telerik:RadTextBox>
<asp:Image runat="server" ID="Image" ImageUrl='<%# Eval("File") %>' AlternateText="Image"></asp:Image>   </ItemTemplate>  </telerik:RadRotator>

c# code:

 //get file attachments                     
  IQueryable<TableName> IqryAttachments = DAL.GetFileAttachments(recordid, "somepagename");
                    rrotAttachmentImages.DataSource = IqryAttachments;
                    rrotAttachmentImages.DataBind();

IE7, IE8 Bar Chart Display Issue

I have a bar chart that displays correctly in IE9, but not IE8 and IE7. In IE8 and IE7 there is also a JavaScript error message: "Error: Unable to get value of the property 'clone': object is null or undefined". The JavaScript error however does not appear if a chart title is specified.
The chart displays correctly in IE8 and IE7 if either: 1. the chart border is removed, or 2. a chart height is speciifed. The error can be reproduced with the following chart. Again, the chart displays correctly in IE9, but not IE8 and IE7.

<telerik:RadHtmlChart runat="server" ID="chart" BorderColor="Black" BorderStyle="Solid" BorderWidth="1">

<telerik:BarSeries Name="2009">

<Items>

<telerik:SeriesItem YValue="116" />

<telerik:SeriesItem YValue="332" />

<telerik:SeriesItem YValue="213" />

</Items>

</telerik:BarSeries>

</Series>

</PlotArea>

</telerik:RadHtmlChart>

Is the HtmlChart compatible with IE7 and IE8? If so, is there a limitation that I'm not aware of, or is this a bug?
Thanks...

Keeping selected records at the top regardless of ordering

Hi all,

Just wondering if anyone has any thoughts on this:

We have an order system where order records are presented in a radgrid for paging, sorting etc.
Some orders may be flagged as urgent (or overdue etc) and I'd like these to always show on the top of the first page irrespective of how the grid is sorted (i.e. by order number or status etc).
Paging away from the first page is not an issue.

Can anyone offer suggestions on the best way to do this?

Cheers
Rich
