[Solved] Grid inside pageview

Hi. I have a several radgrid's inside a several radmultipage's which are accessed via a radtabstrip. Inside the grids, in certain cells appears keywords like "open" and "closed". I also have a literal control at the bottom of the page that I want to populate when the grid's contain these keywords. However, I only want the literal text filled when the user clicks on a particular tab and the keyword exists otherwise the literal is empty. I tried several server side approaches but they are very slow to postback. Can this be done on the client-side? Thanks.

RadMenu center menu text

Hello,
i have a RadMenu with 4 menu items. Over the css selector .RadMenu .rmRootGroup .rmItem i set the width to 75px of every item. I applied a background-image over this selector but how can i center the text of the menu item, so that the text is centered on the background image? The selector .RadMenu .rmRootGroup .rmItem { text-align: center; } doesn't work.

The version is 2009.3 1314

GridBinaryImageColumn Question

I've got a GridBinaryImageColumn in my radgrid. I've got ajax enabled. I've got the javascript to do the disabling for image uploads (args.set_enableAjax(false);). I'm getting the database populated. I'm actually getting data back (binary) when the grid is displayed. HOWEVER, it's never displaying an image. I get a broken image tag because there is no src attribute ever added.

Can someone give me a place to troubleshoot, because I've been through about all I know. Looked into the db, used sql profiler to see what's coming in/out.... just no good. Am I missing something obvious?

My column:
<telerik:GridBinaryImageColumn DataField="Photo" HeaderText="Image" UniqueName="Upload" ImageAlign="NotSet"
                        ImageHeight="80px" ImageWidth="80px" ResizeMode="Fit" DataAlternateTextField="Description"
                        DataAlternateTextFormatString="Image of {0}">
                        <HeaderStyle Width="10%" />

Insert (this is working, data goes to db)
protected void RadGrid1_InsertCommand(object source, GridCommandEventArgs e)
        {

            RadUpload uplPhoto = (RadUpload)e.Item.FindControl("uplPhoto");

            foreach (UploadedFile file in uplPhoto.UploadedFiles)
            {
                byte[] bytes = new byte[file.InputStream.Length];
                file.InputStream.Read(bytes, 0, (int)file.InputStream.Length);

                SPPDataContext data = new SPPDataContext();
                Gallery gal = new Gallery();
                gal.Photographer = (Guid)Membership.GetUser().ProviderUserKey;
                gal.Name = ((RadTextBox)e.Item.FindControl("txtPhotoName")).Text;
                gal.Description = ((RadTextBox)e.Item.FindControl("txtPhotoName")).Text;
                gal.Photo = bytes;

                data.Galleries.InsertOnSubmit(gal);

                data.SubmitChanges();
            }
        }

Pulling data by linqdatasource:

<asp:LinqDataSource ID="ldsPortfolioGrid" runat="server"
                ContextTypeName="SPP.Web.Data.SPPDataContext" OrderBy="Name"
                TableName="Galleries" Where="Photographer == @Photographer"
                onselecting="ldsPortfolioGrid_Selecting" EnableDelete="True"
                EnableInsert="True" EnableUpdate="True" oninserted="ldsPortfolioGrid_Inserted"
                oninserting="ldsPortfolioGrid_Inserting">
                <WhereParameters>
                    <asp:Parameter DbType="Guid" Name="Photographer" />
                </WhereParameters>
            </asp:LinqDataSource>

Selecting is doing nothing exciting either:
protected void ldsPortfolioGrid_Selecting(object sender, LinqDataSourceSelectEventArgs e)
        {
            e.WhereParameters["Photographer"] = Membership.GetUser().ProviderUserKey;
        }

Thanks in advance guys!

Do not use selected format when GridClientSelectColumn checked

I am trying to use a grid as part of a user control to get user input. I have a GridClientSelectColumn. What I would like to accomplish is to continue to use the standard row/alternating row formatting when the row is selected, so that the only difference that the user sees is the checkbox is either checked or not.

Any suggestions?

Thanks!

ReflectionPermission; what's creating the error?

We have a telerik site that my developers are trying to move onto a production hosting environment. The hosting environment provides a marginally modified medium trust level. When we try to run the application, we get a security exception error as shown below. I've read the comments about RadUpload ProgressHandler requiring reflectionpermission, but the app is not using RadUploads, and all references to RadUpload and RadUploadProgressHandler have been removed from web.config.

Is there anything else that would be trying to use reflectionpermission? I have no idea where to begin looking for the issue.

Thanks in advance,

------------------------------------

Security Exception

Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Loading Dockstates from DB

Hi there

I have been experimenting with loading and saving dock states to a DB but have an issue.

When I run the code the docks are not added to the page - rather they are but the source code has a 'style display:none' so I presume this is hiding the docks?? Its all I can think off as I cant see any other issues.

Can somebody have a look below and see what I am doing wrong........

This is the ASPX.................
