c# - Filtering RadGrid by ComboBox -

-

My problem is that when I try to click the cambode inside my Radgrid, it does nothing . 

  & lt; Telerik: Permalink "RadGrid" runat = "server" DataSourceID = "TestReleaseInformationSource" ShowStatusBar = "true" OnItemCommand = "RadGridItemCommand" OnRender = "Radgrid_prerender" Allow DisabledMatic Exceptions = "True" EnableLinqExpressions = "false" AllowautomaticDelatases = "True "Allow paging =" correct "Autogrentech column =" false "allow filteringBickle column =" true "& gt; & Lt; MasterTableView DataKeyNames = "PrimaryKey" & gt; & Lt; Columns & gt; & Lt; Telerich: Allow gridbound columnsFiltering = "True" Unique name = "TeacherLostname" DataField = "TeacherLostname" header text = "last name" & gt; & Lt; FilterTemplate & gt; & Lt; Telerik: RadComboBox id = "radComboBoxLastName" DataSourceID = "TeacherLastNameDDL" DataTextField = "TeacherLastName" DataValueField = "TeacherLastName" AppendDataBoundItems = "Selected" value = '& lt;% # ((GridItem) Container). OwnerTableView.GetColumn ("TeacherLlastName ") .CurrentFilterValue% & gt; Runat = "server" OnClientSelectedIndexChanged = "TeacherLastNameChanged" & gt; & Lt; Items & gt; & Lt; Telerik: RadComboBoxItem text = "All" selected = "true" /> & Lt; / Item & gt; & Lt; / Telerik: RadComboBox & gt; & Lt; Taylor: RadScriptBlock ID = "RadScriptBlock1" runat = "server" & gt; & Lt; Script type = "text / javascript" & gt; Function teacherLlastNameChanged (sender, args) {var tableView = $ find ("& lt;% # ((GridItem) container) .OwnerTableView.ClientID%>"); TableView.filter ("TeacherLlastName", args.get_item (). Get_value (), "Equality"); } & Lt; / Script & gt; & Lt; / Telerik: RadScriptBlock> & Lt; / FilterTemplate & gt; & Lt; / Telerik: GridBoundColumn & gt;   
 on the grid prerender  
  protected zero RadGrid_PreRender (object sender, EventArgs e) {if (RadGrid.EditItems.Count> gt; 0) {GridNestedViewItem Item = (grid nested viittom) radgrid. Mastertableview Getitimes (Griditamtip.Nestedview) [Convert. To INT 32 (Radgrid. Edit indax [0])]; item. View = false; } If (RadGrid.MasterTableView.FilterExpression! = String.Empty) {RefreshCombos (); }} Safe void RefreshCombos () {TestReleaseInformationSource.SelectCommand = TestReleaseInformation.Source.SelectCommand + "WHERE" + RadGrid.MasterTableView.FilterExpression.ToString (); RadGrid.MasterTableView.Rebind (); }   
 I have noticed this for hours and can not understand what the problem is. Any thoughts would be appreciated. If necessary, will post more code.  
 The solution I got is to set the Rendermode property of the company for the company. I still want a different solution.   
 
 
 Try to create JS tasks: I think they all override each other so Only the last one is active so only he is executed. Also, check JS errors.  
 Additionally, try filtering the client as shown here. MasterTableView object is best achieved through the get_masterTableView () method of the main grid object.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
