I am using advanced binding and creating dynamic columns during Page_Init event.
Everything works fine except column groups.

I am creating column groups based on my data and then linking them to columns eventually in page_init event.

Below is the code I am trying to use. Everything is fine on first load. When we try to refresh grid, nothing works. I am getting "Invalid Column Name" error.


            DataSet dsSubmittals = new DataSet();
            DataSet dsCycles = new DataSet();
            string SubID = Session["SubmitalID"].ToString();
            if (Session["SubmitalID"] != null)
            {
                dsCycles = _dv.GetProjectCycles(ProjectID);
                //for (int k = 0; k < dsCycles.Tables[0].Rows.Count; k++)
                //{
                //    GridColumnGroup CycleGroup = new GridColumnGroup();
                //    CycleGroup.HeaderText = dsCycles.Tables[0].Rows[k]["CycleName"].ToString();
                //    CycleGroup.Name = dsCycles.Tables[0].Rows[k]["CycleID"].ToString();
                //    RadGridResults.MasterTableView.ColumnGroups.Add(CycleGroup);

                //}

                //GridColumnGroup CycleGroup1 = new GridColumnGroup();
                //CycleGroup1.HeaderText = "Final Status";
                //CycleGroup1.Name = "Final_Status";
                //RadGridResults.MasterTableView.ColumnGroups.Add(CycleGroup1);

                int index = 4;
                if (dsCycles.Tables[0].Rows.Count > 1)
                {
                    for (int j =1;j< dsCycles.Tables[0].Rows.Count; j++)
                    {

                        string colName = dsCycles.Tables[0].Rows[dsCycles.Tables[0].Rows.Count-j]["CycleName"].ToString();
                        string CycleIdValue = dsCycles.Tables[0].Rows[dsCycles.Tables[0].Rows.Count-j]["CycleID"].ToString();
                        colName = colName.Replace(" ", string.Empty);
                        bool chk = false;
                        for (int k = 0; k < RadGridResults.Columns.Count; k++)
                        {
                            if (RadGridResults.Columns[k].UniqueName != string.Empty)
                                if (RadGridResults.Columns[k].UniqueName == colName)
                                {
                                    RadGridResults.Columns[k].HeaderText = RadGridResults.Columns[k].UniqueName;
                                    chk = true;
                                    break;
                                }
                        }
                        if (!chk)
                        {
                            int loc = index + j;
                            GridBoundColumn bf = new GridBoundColumn();
                            bf.DataField = colName.Trim();
                            bf.HeaderStyle.Width = 55;
                            bf.FilterControlWidth = 22;
                            bf.UniqueName = colName.Trim();
                            bf.HeaderText = colName.Trim();
                            bf.HeaderText = colName.Trim();
                            bf.SortExpression = colName;
                            bf.FooterText = CycleIdValue;
                            bf.HeaderButtonType = GridHeaderButtonType.TextButton;
                           // bf.ColumnGroupName = "Final_Status";
                            RadGridResults.MasterTableView.Columns.AddAt(loc, bf);

                           

                        }
                    }
                }

Hi,

I use the RadEditor inside a input form with dynamic content. Dependent of the selected record in a Radgrid different input control become visible. When an input control is not visible, its replaced to a seperate div to make room for other input controls. Because the RadEditor is replaced on the DOM I call editor.OnParentChanged() to let the RadEditor behave as expected especially in Firefox and IE 10 and lower. If I don't the RadEditor steals focus and its content becomes empty.

This works great when the RadEditor becomes visible, but when the RadEditor becomes invisible it still steals the focus.This is a problem for pressed shortkeys in the RadGrid to navigate through records because they stop work after the focus is stolen. The content of the RadEditor stays filled when it is invisible as expected.

The strange thing is, the focus is not stolen the first time the RadEditor becomes invisible.

Any ideas what goes wrong in my situation?

With the Microsoft Validator controls (RequiredFieldValidator in this case) the typical behavior is for validation logic to run when you tab out of the field, or on submit. 

I have noticed with RadComboBox this is **not** the case, even in your own online demo. Rather, with RCB validation *only* occurs when you attempt to submit. Is there any way to force this to validate on tab out? Typically the field would look something like this in code:

Hi,

Has anyone tried using ESRI shape files as a datasource to populate the shapes layer?  We have a considerable number of geographical boundaries and point locations stored in ESRI shape files and would like to see if there is a reasonably simple way to use them to populate the shapes layer in the Telerik map control.

Folks, using UI for ASP.NET AJAX Q2 2014 SP1 with VS 2010.

In My Radgrid, I have Cancel Confirm both for Parent and Child Grid. Cancel Confirm works well in Parent Grid. Not an issue there.

But in Child Grid,  Cancel Confirm does not work; edit form stays open. AllowAutomaticInserts="false" AllowAutomaticUpdates = "false" in Child Grid.

Below is my client side code.



Below is my Item command for the Command for the Child Grid.



Thanks for any Help.

Hi,

I am trying to use a PanelBar from one of the samples.
I need just one panel to make it a collapsible panel for advanced options.


I can click on the panelBar to extend it, but it does not want to collapse.

Is the PanelBar the correct control for this ?
Or am I doing something wrong ?

Hello everybody,

i use the telerik RadScheduler and the Timeline-View.

I will export the current view to PDF. The HTML-View shows all correct.
In the PDF the inline row of the timeline is smaller then the vertical headers. (Take a look to the Attachment)

The html and pdf have the same css files.

My C# code:


My aspx:


What can I do? Is this a problem with the PDF-Exporter?

Best regards
Tobias
