Questions on UI for ASP.NET AJAX Forum

Hi Team,
I tried following steps to use RadMultiSelect dropdown in my project but getting compile time error .
1) I have registered Telerik.Web.UI assembly in aspx page
2) Added RadScriptManager and RadSkinManager on aspx page.
3) then added following code -
<telerik:RadMultiSelect runat="server" DataValueField="text" Filter="Contains" EnforceMinLength="false" Placeholder="Select Receiptees"
DataTextField="text" Width="500px" ID="requiredMultiSelect">
<Items>
<telerik:MultiSelectItem Text="Steven White"></telerik:MultiSelectItem>
<telerik:MultiSelectItem Text="Nancy King"></telerik:MultiSelectItem>
</Items>
</telerik:RadMultiSelect>
4) added this line in aspx.vb file for default selection
requiredMultiSelect.Value = {"Anne King", "Andrew Fuller"}

And getting compile time error -
Type 'Global.Telerik.Web.UI.RadMultiSelect' is not defined.

Not able to find solution for this on telerik webpage also , Can anyone please help me with this?

RadGrid Master-Detail with Insert on Detail Table.. How to?

Hi,

Long time Webforms developer here, but just starting out with Telerik Rad controls.

I can't for the life of me figure out how to get the "Insert Record" button to show up on my Grid that has a Master-Detail relationship.

I looked at the code sample and can't figure out what I am missing.

Any help you could provide would be appreciated.

Problem getting and filtering from the headers of a radgrid, which is loaded dynamically via sql server views.

DLL: Progress Telerik UI ASP NET AJAX Versión 2020.2.617.40

Hi!,
I have a problem with dynamically loading data, and subsequently filtering data from the headers of a radgrid.

The radgrid data is loaded dynamically through the selection of a radcombo with Id "rcb_Views", and this loads a sql server database view into a sql SqlDataSource "eds_Generic" and binds it to the grid.

The problem is that filtering by grid headers also has to be implemented, and it works if the selection in the combo does not change. But when the selection, in order to load a new data view, and regenerate all the data in the radgrid, it gives an error:

"[column] is neither a DataColumn nor a DataRelation for the DefaultView table.

The problem seems clear, and it is that it does not refresh either the model or the data, since the error column belongs to the schema of the model of the previous view, but I have not been able to solve it by changing the data source of the data, doing a rebind, etc. .

Can someone guide me on how I can correct the problem?

Has Telerik gone downhill? Errors and errors first time use.

I've used Telerik for 15 years, or when it came out. I've stepped away from development as I moved up in ranks. Today, I'm going to develop an application. I purchased the software, installed it and opened Visual Studio. After opening Visual Studio, I selected "Telerik Web Forms Application" and clicked next. I selected a blank project from the Progress create new project screen. The app did it's thing and i was presented with a project with a Default.aspx. I tried to run it and it is nothing but errors, ( Unknown server tag 'telerik:RadStyleSheetManager'.) (telerik, unknown tag prefix and so on) This has never happened in the past and I'm following Teleriks own project start. SMH. So much for quickly knocking out an application. Now I have to spend time trying to Unscrew Telerik's poor quality deployment and installation. SMH! So frustrating and annoying.
So, what hoops do I need to jump through to get this working that was not done when I used Telerik to build this project?

                            <a href="#" class="orderInfo">details&nbsp;&raquo;</a>
                        </div>
                    
The Telerik answer about adding a PDF file says use the PDF's iFrame to add to the RadRotator, but iFrames are deprecated, and there is no iFrame in this code.  Can anyone provide a modern solution that specifically shows how to add an existing PDF file to a RadRotator?

Rad Grid and Details table - getting master id and passing to detail table

Hi all

I have a radgrid with 1 detail table.

The master table retrieves data using a SQLDataSource ,a stored procedure and session value as a parameter - this works fine.

The detail table also uses a SQLDataSource and a stored procedure but the parameter for this is the key field from the master table and not a session field.

How do I go about grabbing the key field from the master and pass it to my stored procedure?

Any help greatly apprciated.

RadGrid.MasterTableView.FilterExpression Exception

Hello

i'm stuck with a simple example.

I have a RadGrid with multiple column avec ExcelFilter activated.

When in a column, you have data like 'test AND test' the Filter got no FilterExpression when you select this particular line in the filter with a tickbox.

If you use the Filter fonction normally (Contain) it work.

Here is a simple exemple.

public partial class Default : System.Web.UI.Page

    protected void ContextGrid_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

        DataTable table = new DataTable();
        table.Columns.Add("Creation", typeof(string));
        table.Columns.Add("Name", typeof(string));

        int i = 0;
        for (i=0; i < 10; i++)
        {

            table.Rows.Add(

                ) ;
        }
        return table;
    }

}

Selection and Error in the 2 captures.

Works with OR also.

Any Clues ?

Thinks it's the same error like the quote.

Thanks a lot
