Hi all:

I am working with this example:

http://demos.telerik.com/aspnet-ajax/upload/examples/async/webmail/defaultcs.aspx?product=asyncupload

However I do not understand how to read the file data from the uploaded files. I need to read the files into a byte array. Here is the code:

PopulateUploadedFilesList();
if (UploadedFiles != null)
{
AttachmentRepeater.DataSource = UploadedFiles;
AttachmentRepeater.DataBind();
for (int i = 0; i<UploadedFiles.Count; i++)
{
       #region get file content
       // Open a file and read the contents into a byte array.
       FileStream stream = File.OpenRead(UploadedFiles[i].FileName);
       byte[] byteData = new byte[stream.Length];
       stream.Read(byteData, 0, byteData.Length);
       stream.Close();
       // Encode the data using base64.
       string encodedData = System.Convert.ToBase64String(byteData);
     }
}

Any and all help is greatly appreciated.

John.

Apply specific header filter from code behind

I have a RadGrid on my page that I use as a selector, and via it's SelectedIndexChanged I wanna set some header filter on another grid.

Each time the selection is changed in the first RadGrid (rgPendingRequests) I want to adjust the header filter of rgResponsables and filter the result. The user must then be able to change the header filter as he wish, in case the filter returns nothing.

This is the grid I wanna apply the header filter to

<telerik:RadGrid

ID="rgResponsables"

runat="server"

Width="100%"

Height="220px"

AutoGenerateColumns="False"

EnableViewState="true"

AllowFilteringByColumn="True"

AllowSorting="True"

CssClass="gridPartageResponsables"

EnableLinqExpressions="false"

>

<GroupingSettings CaseSensitive="false"></GroupingSettings>

<ClientSettings EnableRowHoverStyle="true" Selecting-AllowRowSelect="true" EnablePostBackOnRowClick="true" Scrolling-UseStaticHeaders="true" />

<MasterTableView

DataKeyNames="ResponsableID"

AllowFilteringByColumn="True"

>

<Columns>

<telerik:GridBoundColumn DataField="Prenom" Visible="true" HeaderStyle-Font-Bold="true" HeaderText="Prénom" UniqueName="Prenom" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false" />

<telerik:GridBoundColumn DataField="Nom" Visible="true" HeaderStyle-Font-Bold="true" HeaderText="Nom" UniqueName="Nom" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false" />

<telerik:GridBoundColumn DataField="Courriel" Visible="true" HeaderStyle-Width="250px" HeaderStyle-Font-Bold="true" HeaderText="Courriel" UniqueName="Courriel" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false" />

<telerik:GridBoundColumn DataField="Telephone" Visible="true" HeaderStyle-Width="120px" HeaderStyle-Font-Bold="true" HeaderText="Téléphone" UniqueName="Telephone" AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

Here is my code Behind:

Protected Sub rgPendingRequests_SelectedIndexChanged(sender As Object, e As EventArgs) _

Handles rgPendingRequests.SelectedIndexChanged

Dim PrenomCol = rgResponsables.MasterTableView.GetColumnSafe("Prenom")

PrenomCol.CurrentFilterFunction = GridKnownFunction.Contains

PrenomCol.CurrentFilterValue = rgPendingRequests.SelectedValues("FirstName")

Dim NomCol = rgResponsables.MasterTableView.GetColumnSafe("Nom")

NomCol.CurrentFilterFunction = GridKnownFunction.Contains

NomCol.CurrentFilterValue = rgPendingRequests.SelectedValues("LastName")

rgResponsables.Rebind()

End Sub

But even though the values appear in the header filter, the table is not filtered until I go to a header filter field and press enter...

I've tried everything I can think of, and could not make it work...

I could really use some pointer on what I'm doing wrong...

contains-filter with client api doesn't work

Hello,

we have a grid with client databinding. Backend is a WCF web service.

The requirement is, the client side column filter setting(user has a filter text in the column Title) shall be restored if the page has been reloaded(for example after adding a new item).

But the Contains-filter doesn't work with part-match. It works only if the filter-text equals the Title(full match). It is the same with StartWith-filter.

What wasI wrong?

The Telerik.Web.UI assembly version is 2015.2.826.45

Please help. Thanks.

function applyFilter() {

var grid = $find("<%= RadGrid_PublishedDocuments.ClientID %>");

var tableView = grid.get_masterTableView();

var column = tableView.getColumnByUniqueName("Title");

column.set_filterFunction("Contains");

tableView.filter("Title", "dcr", Telerik.Web.UI.GridFilterFunction.Contains, true);

tableView.rebind();

}

How to force CSS to reload using RadStyleSheetManager?

Hi,

It is common practice to do something such as this:

<link rel="stylesheet" type="text/css" href="../Content/Dashboard/Dashboard.css?t=<%= DateTime.Now.Ticks %>" />

This is for development purposes, and would be converted to something like ?v=[Version Number] for releases. This is to force browsers to reload CSS instead of using cached versions.

If I attempt to use the same syntax inside of RadStyleSheetManager I am told I am using illegal characters. Does Telerik's control support something like this?

Thanks

Sean

Filter not working for DateTime columns with "equal To" filter

I can't get the filters for 'equal to' working on date time column in rad grid. As far as I can tell this has something to do with the times on the dates. I have seen many posts about this here with no answer so I guess I don't really expect help, but just throwing my voice in with everyone else saying your filters don't work right for date time columns. Period.
