Hi,

When i add a field  programmatically:

Button1_Click:


when i interact with him, it raises an error:

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Value cannot be null.
Parameter name: fieldInfo

what is the issue ?

sorry my poor english.

I am trying to get a site to work with a free screen reader (NVDA). I am making the fields more accessable by setting the AssociatedControlID of the asp:Labels to the associated fields. This technique works well for RadTextBoxes, but so far, it has not worked (NVDA will not read the label when the focus is on field) for any RadComboBoxes. Here is what the label / RadComboBox combo looks like:

I followed the instructions here to auto resize my columns, but this doesn't appear to work if ShowHeader = false.  

http://www.telerik.com/help/aspnet-ajax/grid-gridcolumn-resizetofit.html.  

If ShowHeader = false, it looks like it resizes the columns so that the whole table is 100% of the screen, ore maybe even a bit more.  Is there a workaround for this?  Could I hide the header row on the client side after running resizeToFit()?

i use RadMediaPlayer in my project and i want in playlist add both audio and video. my code is: SqlConnection con = new SqlConnection(System.Web.Configuration.WebConfigurationManager.ConnectionStrings["conection"].ConnectionString);
SqlCommand cmd = new SqlCommand("SELECT Extension,Detail,Link,Title,Folder,Pic FROM [TblQuality] WHERE mId=@mId", con);
cmd.Parameters.AddWithValue("@mId", QSi);
SqlDataReader dr;
MediaPlayerFile file;
using (con)
{
con.Open();
dr = cmd.ExecuteReader();
while (dr.Read())
{
if (!dr.GetString(2).ToLower().EndsWith(".rar") || !dr.GetString(2).ToLower().EndsWith(".zip"))
{
//new media
if (dr.GetString(2).ToLower().EndsWith(".mp3"))
{
file = new MediaPlayerAudioFile()
{
Poster = string.Format("~/Management/images/Music_img/{0}/{1}", dr.GetString(4), dr.GetString(5)),
Path = string.Format("~/Cnt/Music/{0}/{1}", dr.GetString(4), dr.GetString(2)),
Title = string.Format("{0}.{1} - {2}", dr.GetString(3), dr.GetString(0), dr.GetString(1))
};
RadMP1MusicDown.Playlist.Add(file);
}
else
{
file = new MediaPlayerVideoFile()
{
Poster = string.Format("~/Management/images/Music_img/{0}/{1}", dr.GetString(4), dr.GetString(5)),
Path = string.Format("~/Cnt/Music/{0}/{1}", dr.GetString(4), dr.GetString(2)),
Title = string.Format("{0}.{1} - {2}", dr.GetString(3), dr.GetString(0), dr.GetString(1))
};
RadMP1MusicDown.Playlist.Add(file);
}
}
}
dr.Close();
cmd.Cancel();
}but when load page, media play are only in audio mode or video mode.if first item is mp3 and second is mp4 when video play mediaplayer don't show video only play sound.can help me fix this?

How can i hide the grid when grid is bound to a null collection?

If i set grid visibility to false on grid_NeedDataSource event then no data is displayed even next time when it is bound  with some valid data.

Protected Sub gridConsolidation_NeedDataSource(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles gridConsolidation.NeedDataSource

    'Get filtered object data whose functional and technical improvement recommended

    Dim filterExpression As String

    filterExpression = String.Format("Opportunity_Id = {0} and Recommendation_Type_Id In ({1})", ddlOpportunity.SelectedValue, _

                                     CType(RecommendationType.Consolidation, Integer))

'dtRecommendationInitiative is a datatable to be used as grid datasource

    Dim dt As DataTable = GetFilteredDataview(dtRecommendationInitiative, filterExpression)

    Dim dataCount As Integer = dt.Rows.Count

    gridConsolidation.VirtualItemCount = dataCount

    gridConsolidation.AllowCustomPaging = Not ShouldApplySortFilterOrGroup(gridConsolidation)

    gridConsolidation.DataSource = dt

 

    'If gridConsolidation.Items.Count > 0 Then

 

    '    divConsolidationGrid.Style.Value = "display:block"

    '    btnMergeToExisting.Visible = True

    '    btnMergeToNew.Visible = True

    '    btnSave.Enabled = True

I have a form with a number of fields before a RadMaskedTextBox and a number of fields after. In Chrome or Opera, when the focus is placed on the RadMaksedTextBox, the validation must pass, or you cannot tab or click out of the field, which is not the expected behavior. Here is an example exhibiting this behavior.

Hello,

I'm currently working on a project with RadGrid.

It is possible to add to the list of the columns, "select all/none" checkbox?

Thanks,
Daniel
