function onTabSelecting(sender, args)

{

if (args.get_tab().get_pageViewID())

{

args.get_tab().set_postBack(

false);

}

}

Hi,

I think I have quite a specific task. I have a page, where I need to generate multiple grids, for different types of entities.

And the thing is that on grid generation step I do not know types of entities that I will have, in other words I have a set of 'Type' entities each describing some class, so I can not declare grids in 'aspx' page, but I need to generate them in code behind.

I am trying to generate grid in the code behind using this code:

var grid = new RadGrid();
grid.AutoGenerateColumns = true;
grid.MasterTableView.EditMode = GridEditMode.InPlace;
grid.DataSource = input.GetDataForEngineQueryPosition(job, metricKey); //just collection of entities
grid.Visible = true;
grid.DataBind();

Quite simple, and the code is working, I do see the grid with appropriate columns, but I cant edit the values in the cells.

I also tried to generate columns manually depending on properties provided by 'type' entity, like this:

var grid = new RadGrid();
grid.AutoGenerateColumns = false;
var propertiesBindingFlags = System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance;
var customizableFields = input.CustomizableProperties;
bool showAll = false;
                
foreach(var property in inputType.GetProperties(propertiesBindingFlags))
{
  var field = new Telerik.Web.UI.GridBoundColumn();
  field.DataField = property.Name;
  field.HeaderText = property.Name;
  field.ReadOnly = false;
  field.Visible = true;
  grid.Columns.Add(field);
}
grid.MasterTableView.EditMode = GridEditMode.InPlace;
grid.DataSource = input.GetDataForEngineQueryPosition(job, metricKey);
grid.Visible = true;
grid.DataBind();

Values are displayed correctly in this case, but unlike for the autogeneration I don't see proper controls for every column (like checkbox) and I understand why.

But I still can't edit the values in the cells.

Also, after updating the values I need to submit them back to the server, what is the best way to do this. 

Thanks.

Kind regards,

Erik Martirosyan

This is the error...

Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near ':"text/javascript"}

I have read some other older threads about this but I am not sure what the actual issue is.  We just recently upgraded our telerik after a couple years and now this error is popping up everywhere.  Never had this issue before.  We use RadAjax Manager, RadAjax Panels, and RadAjax loading panels in a lot of places and that seems to be were the issue always pops up.  Need some guidance on how to remedy this issue without having to downgrade the telerik version because we upgraded to fix other issues with radeditors and jquery.  Please help when you can and let me know if you need more info.

Hello,

Radgrid, Require to have some column disable edit. Some Cell Disable Edit.

Able to achieve by cell opening to block, but "TAB" key stopped and jump out of Radgrid. User require to get mouse back for next cell to open edit mode again.

Any possible way to simulate Tab key move to next cell at batch edit opening ?

  function BatchEditOpening(sender, args) {

                    var row = args.get_row();
                    var cell = args.get_cell();
                    
                    // cancel edit based on cell data ***
                    var content = $telerik.$(cell).text().trim();
                    if (content == "three") {
                        args.set_cancel(true);      

====== How to tab focus cell opening to next cell ??
====== args.get_cell(); does not have cell index

====== so that batchManager1.openCellForEdit(??? how to call next available cell ?? ) 
                    }

 }

I have a radgrid with 2 columns at 400px each. I have set the width of the grid to 600px and AllowScroll=true. I also have AllowColumnResize=true, when i resize column 1 to 500px by dragging, it will automatically resize column 2 down to 300px, maintaining the original overall width of a combined 800px for the 2 columns. Is there anyway to maintain the size of column 2 when column 1 is resized such that column 1 is the new resized 500px and column 2 stays at 400px, increasing the overall combined size to 900px? I looked at ReizeGridOnColumnResize=true but that causes my grid width of 600px and allowscroll to be ignored and the width of the grid is displayed as the full 900px causing the rest of my page layout to be stretched.

                               <telerik:RadGrid ID="RadGrid1" runat="server"
                                ClientSettings-Scrolling-AllowScroll="true"                                     
                                OnNeedDataSource="RadGrid_NeedDataSource"
                                height="200"
                                Width="600">
                              <ClientSettings>
                                <Resizing AllowColumnResize="True" ResizeGridOnColumnResize="false" />
                              </ClientSettings>
                                <MasterTableView AutoGenerateColumns="false" >
                                    <Columns>

                                        <telerik:GridTemplateColumn HeaderStyle-Width="400" HeaderText="2">
                                        </telerik:GridTemplateColumn>                                        
                                    </Columns>
                                </MasterTableView>
                            </telerik:RadGrid>

Hi,

When looking at MetroTouch (and other) skin on FF, Edge and Chrome we see a little discrepance in the stepper bar, see attached.

This will be solved when altering css like so:

.RadWizard .rwzBreadCrumb .rwzLink::before {

    right: -0.5em;}

original value is:

right: -0.6em;

Marc

Change value by mousewheel does not work in Edge (Microsoft Edge 44.17763.1.0, Microsoft EdgeHTML 18.17763), Chrome is ok
