RadGrid and Entity Framework in Code-behind

Hi dear friends!

Do you have a sample of asp.net webforms page populating a radgrid with entity framework objects in code behind. Example:

    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            ClientsContext db = new ClientsContext();
            var query = from b in db.Clients orderby b.LastName select new { Client = b.ClientId, First = b.FirstName, Last = b.LastName, County = b.CountyName, City = b.City };
            GridView1.DataSource = query.ToList().Take(100);
        }
    }
}

Your support will be greatly appreciated.

Exchange provider Guid ID on Insert / Update

Hello,

I would like to know if you have any idea about the following issue :

After an insert , i have some CRUD method to insert or deleting an appointement . In our system , the ID stored is a long and Outlook generate a string (guid?)

The thing is if i want to synchronize both systems , i need to match on the ID but in this case , they are different .

It seems that my insert method is executed first (Debug), and then the Exchange provider insert the new appointment (successfully) .

Is there a way to get the newly guid ID created by the ExchangeProvider ? In that case , it will be easier to create an ExternalID on our database .

Thanks a lot for your help,

Issou

I need your help to populate the data on RadSlidingPage once any row or data insertion happaned from the Child Page.

Idea -
RadSlidingPage has TreeView. Under the treeview, there is Combobox. This combobox will be listing all drivers.

I am using Telerik Version 2014 Q1. I kept RadSlidingPage in masterpage. I have a child page where I am doing DB interaction through Insertion, Edit or Deletion operation. If we do any insertion of driver details. RadSlidingPage has to get refresh or reload. Jus moment before added driver should be listed in RadslidingPage's combobox. I trying to do with javascript but unable to get it.

Please help to achieve this. Thanks in advance.

Radgrid exporting to excel using html format has issue with date formating

Hi,

I am using radgrid excel export using html format. In radgrid ExportCellFormatting event we are formatting the date column as below

If e.FormattedColumn.UniqueName = "t_UploadedOn" Then
e.Cell.Style("mso-number-format") = "dd\-mm\-yyyy\ HH\:mm\:ss\"
End If

The above works fine if date is something like 29-01-2015, but if date is like 1st of Feb 2015 then it will show as 02-01-2015. Please see the attached screen grab of recent export.

Any help would be greatly appreciated.

Problems using Metro Touch in Ribbon, style hell

I am using the metro touch skin form my interface to get bigger touch menus, boxes and buttons - looks great.

In the ribbon editor interface, using metro touch messes up the html tab. The top text cannot be seen and the scroll bars are messed up. So I switched to the default skin for the editor while the rest of the interface stays in metro.

The question, how do I do this? My editor is lacking styles. The editor interface in the middle with a big gap at the top which I know from previous experience is a style problem. How can I make my editor use a default skin while in metro touch?

Another solution would be getting the HTML window in Metro Touch to work, huge bug there.

Help please,
George

RadMenu style

Hello,
is there a simple way to make the RadMenu header button like the RadToolBar Button?

I have a toolbar with a button with a template. Into this template there is a RadMenu but the style is completely different.
Look at the attached picture.
I'd want the menu "item menu" looks like "item Save" in normal state and like "item add" when is hovered.

Thanks
Maurizio

RadTextBox text after rebind

My Grid has a RadTextBox that is being used to filter on all the columns. It Looks like this:

<telerik:RadGrid runat="server" ID="grid1" GridLines="None" ShowFooter="False" Culture="de-DE">

<MasterTableView AutoGenerateColumns="False" AllowMultiColumnSorting="True" CommandItemDisplay="Top">

<CommandItemTemplate>

<telerik:RadToolBar ID="radToolBar" Skin="Windows7" runat="server" AutoPostBack="true" Width="100%">

<Items>

<telerik:RadToolBarButton Value="section2">

<ItemTemplate>

<telerik:RadTextBox ID="textbox1" runat="server" Skin="Windows7"><ClientEvents OnKeyPress="OnKeyPress" /></telerik:RadTextBox>

<telerik:RadButton ID="btnSearch" runat="server" Skin="Windows7" Text="Search" CommandName="Search" OnClick="searchButton_Click"/>

</ItemTemplate>

</telerik:RadToolBarButton>

</Items>

</telerik:RadToolBar>

</CommandItemTemplate>

</MasterTableView>

<GroupingSettings CaseSensitive="False" />

</telerik:RadGrid>

Now when I click the button to do the filtering, this function gets called.

protected void searchButton_Click(object sender, EventArgs e)

{

RadTextBox searchFilter = GetSearchBox();

if (searchFilter == null) return;

var filterExpression = new StringBuilder();

var searchText = searchFilter.Text;

foreach (GridColumn col in grid1.MasterTableView.Columns)

{

filterExpression.AppendFormat("{0}(it[\"{1}\"].ToString().ToUpper().Contains(\"{2}\".ToUpper()))",

filterExpression.Length != 0 ? " OR " : string.Empty, col.UniqueName, searchText);

}

activePassiveGrid.MasterTableView.FilterExpression = filterExpression.ToString();

activePassiveGrid.MasterTableView.Rebind();

}

This works as expected. But after the Rebind(), the filtering becomes active, which clears the text in my textbox. I don't want it to be cleared, so you can still see what your filter searches for. Is it somehow possible to keep the text in the textbox?

Double-Click Expander

Hi,
I was wondering if it was possible to change the functionality of the TreeView to expand on double click of the arrow, rather than just of the parent item?
Thank you for any help.

Radgrid page size disappears

I'm using a radgrid with paging and page size on my site. But for some reason, the page size dropdown disappears when I make it big enough to display all the results on one page. So if there are 21 record in the radgrid and I set the page size to 50 then the page size dropdown disappears. The pagination controls disappear as well but that makes sense. But I need to give the users the ability to go back to displaying 10 records if they want.

<telerik:RadGrid ID="AdministratorRadGrid" runat="server" AllowPaging="True" AllowSorting="true" OnItemCommand="AdministratorRadGrid_ItemCommand"

OnSortCommand="AdministratorRadGrid_SortCommand" OnPageSizeChanged="AdministratorRadGrid_PageSizeChanged"

OnPageIndexChanged="AdministratorRadGrid_PageIndexChanged" PagerStyle-Position="TopAndBottom">

<MasterTableView AutoGenerateColumns="False" DataKeyNames="BWUserRoleID">

<Columns>

<telerik:GridBoundColumn DataField="BWUserRoleID" HeaderText="ID" ReadOnly="true" Visible="true"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="DisplayName" HeaderText="Name" ReadOnly="true" FilterControlWidth="150px" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Title" HeaderText="Title" ReadOnly="true" FilterControlWidth="50px" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains"></telerik:GridBoundColumn>

</Columns>
