Dear All,

   I'm very new guy here. and I had two RadListBoxItems in my aspx page. ListUserCols and ListAllCols.  and while I'm loaded some of the values through DB in ListUserCols for manualy selected items. and then I loaded all of my 50 items in ListAllCols listbox.!

  Now, I need to check from Second Listbox items(ListUserCols) not exist in First Listbox items. Please help me to find out resolved that issue.. I'm searched google in many time. No results are found. Moreover, i didn't select any Items in listbox, all loaded from DB.

Sample code:

                     DataSet dsAttributes = new DataSet();
                      foreach (DataRow dr in dsAttributes.Tables[0].Rows)
                        {
                            lstUserColumns.Items.Add(new RadListBoxItem(dr["Column_Desc"].ToString()));
                        }

                      

                        foreach (RadListBoxItem selectedItem in lstUserColumns.Items)
                        {
                            //lstAllColumns.Items.Remove(new RadListBoxItem(selectedItem.Value));
                            RadListBoxItem item = lstAllColumns.FindItemByText(selectedItem.Text);
                            item.Remove();
                        }                       
                    }

Could you show me a sample for add,remove,change text with a RadTreeView and save to database?
I tried many ways but never work.
At first I face "id" problem,these create by JavaScript doesn't have Value to be "id".
Then I face "parentID" problem,because parentNode is create by JavaScript so it have no Value to become "parentID"
And many problems.

(I am trying to create a new tree,the database is empty)

Could you give me a sample for Client-Side add,remove,change text,and postback to save to Database?

Thanks!

Hello everyone,

first some tecnical details:

We use the Telerik Controls in Version 2014.2.708.45
Our problem occuring with IE 8, 9, 10 and 11.
We use .Net Framework 4.5

Our problem is the following one:

We have an ajaxified RadTabStrip connected to a RadMultiPage. We create the pages connected to the tabs dynamically as done in this demo. The page views contain a usercontrol. The usercontrols contains some RadTextBox controls. All Textboxes have a label, where the LabelWidth is set to 250px. The width property of the textbox is set to 100%.

The following is done by css:


How it should look can be seen in the attached file SampleTelerikUserControl.png. This works fine in all browsers if the usercontrol is directly added to a page.

If the usercontrol is added dynamically in ajaxified TabStript/PageView the textbox controls have not the correct width (only in IE, in all other browsers the controls are properly rendered - the width ignores the 250px from the lable). If you click another tab (and and something is done through ajax) and than switch back to the first tab with the wrong rendered usercontrol the controls of the usercontrol are now properly displayed. The wrong behavior could be seen in ErrorTelerikUserControl.PNG, the correct behavoir is shown in OkTelerikUserControl.PNG (after the first ajax call).

Thanks

I'm creating dynamic multi header radgrid and inside the rows used colspan as well. everything works fine until i do horizontal scroll. during the horizontal scroll the cells are collapsed and some cells are missing. everything went wrong if we do horizontal scroll. any solution to fix this issue?

Hi,

I have created a treelist with treelist select column and allow multi select.

1) When I have selected two nodes, if I select a node by clicking on the node it select that particular node. That behavior is correct.
But when I click the checkbox(select column) it deselects that row. I want to select the row that user clicked irrespective of clicking on the node or
checkbox (select column).

 

2) I have enabled the dragging operation in the treelist. I want to know whether I can delay the start of dragging operation. It seems dragging is
starting as soon as I try to select a node. I can see as user click on the row preview image of dragging node is visible. It disappears quickly. 
But it is does not look nice. This happens with the node selection and slight movement of the mouse which makes start of drag operation

 
I have attached some screenshots for reference

Any help is highly appreciated.

Hi,

I am using radpivotgrid control in my webpage to display data from a Olap Cube.
I want to create a new measurement after I have done some calculation on the my data.
The newly created dimension will need to show its value on the pivotgrid.
Do you have any idea on creating a new dimension (perhaps using MDX) and display it on the pivotgrid?  
Thanks.

hi,
need ideas to have a media player which plays selected media file across all pages. have master page and placing radmediaplayer in footer, but player starts playing from beginning when navigating across pages....help is appreciated. ty

Hi,
I am using two Rad grids on one of my page. There are some DateTimeColumns created for each of them for DateTime fields. Dates are displayed correctly in DateTime column. 
When I apply filter on DateTime column, it works in one grid but throws exception in another grid, although code is same for both. There is no custom filtering.

For both grids, DateTimeColumn is added programmatically as below:
-------------------------------------------------------------------------------------------------------------------------
GridDateTimeColumn boundColumn = new GridDateTimeColumn();

ProductsGrid.MasterTableView.Columns.Add(boundColumn);
boundColumn.PickerType = GridDateTimeColumnPickerType.DatePicker;
boundColumn.FilterControlWidth = Unit.Pixel(100);
boundColumn.HeaderStyle.Width = Unit.Pixel(110);
boundColumn.DataField = col.SystemName;
boundColumn.UniqueName = col.SystemName;
boundColumn.EnableTimeIndependentFiltering = true;
boundColumn.HeaderText = col.FriendlyName;
boundColumn.DataFormatString = "{0:dd/MM/yyyy}";
boundColumn.AutoPostBackOnFilter = true;
boundColumn.SortExpression = col.SystemName;

boundColumn.CurrentFilterFunction = GridKnownFunction.GreaterThanOrEqualTo;
boundColumn.ShowFilterIcon = true;

boundColumn.Display = col.Visible;
-------------------------------------------------------------------------------------------------------------------------

Exception I am getting while filtering by DateTime Column is :

-------------------------------------------------------------------------------------------------------------------------
Exception Type: Telerik.Web.UI.ParseException

Message: Neither of the types 'String' and 'DateTime' converts to the other
