Hi all,

 

I'm using grid view to display my data. All works well but all names which start with "US_TV" are ellipsis automatically but cell length is wide enough to display all content.

Don't know what's problem ????

 

Hi 

I want to draw a diagram similar to the one in the attached image.

It will be great if the names of vertical lines could be frozen to the top section of the diagram.

The user should not be able to modify the diagram.

 

I have a very simple grid - its blank.  No rows, no columns.  The grid control's name = gg

In Code I add one column:  GridViewTextBoxColumn() like this:

 

Dim myCol As GridViewDataColumn = Nothing

myCol = New GridViewTextBoxColumn()
myCol.DataType = GetType(String)
myCol.Name = "Test Texteditor"
myCol.FieldName = "TestText"

myCol.HeaderText = "TestText"
myCol.ReadOnly = False
myCol.IsVisible = True

gg.Columns.Add(myCol)

 

I have another method that creates a row for testing.

I've checked ReadOnly on:  Grid, Row, Column and Cell.  ALL are ReadOnly = False

but when I double-click on the cell - nothing happens.  No Text Editor nothing.  At first I thought, ok I'm creating this column dynamically so there must be some methods I'm supposed to hook into (AddHandler) and specifically I figured I'd need to hook into EditorRequired but there's no such method for a GridViewDataColumn() so I'm really stuck.

 

I'm 100% certain I'm doing something stupid and any help or nudge or shove in the correct direction would be very appreciated.

Thank you!

-Curtis

 

 

Hi

I want to clear the pivotgrid contents.

I am using LocalDataSourceProvider and providing datatable as itemsource.

If I set the LocalDataSourceProvider object to null, I get NullReference exception.

I have emptied the rows and columns, but the grid does not refresh.

Is there meanwhile a way to control the position of the axis crossing ? It's strictly fixed to an outside corner of the ChartArea ?

I found this old thread with an answer, may be things have changed meanwhile

https://www.telerik.com/forums/drawing-x-axis-on-chart-view-at-zero-when-negative-values-exist

RadChartView is such a rich thing, it's on wonder while such a basic feature as control the axis crossing is missing.

That means a 4 quadrant chart (going f.e. from -100 to +100 on both axis, with having the axis crossing at (0,0)) is strictly impossible ?

Symptoms:
Telerik Document Processing which is used in most of the exporters in UI for WinForms is affected after you install January 9, 2018, .NET Security and Quality Rollup (KB4055002). Applications that request a fallback font or a character that is not included in the currently selected font return the following error messages:
System.TypeInitializationException
“FileFormatException: No FontFamily element found in FontFamilyCollection that matches current OS or greater: Win7SP1”.
Inner exception originates from: CompositeFontParser





Solution 1:
Microsoft has released an update which fixes the issue. More information about it you can find here: Description of the Security and Quality Rollup for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, and 4.7.1 for Windows 7 SP1 and Server 2008 R2 SP1 (KB 4074880).

Solution 2:
To keep .NET 4.7.1 installed and maintain protection against vulnerabilities that are addressed by the January security updates, uninstall the January .NET Framework Security and Quality Rollup (KB 4055002), and then install the January .NET Framework Security-Only Update (KB 4054183). To do this, follow these steps:
1. In Control Panel, open the Windows Update item, and then select View update history.

hi telerik

                foreach (GridViewDataRowInfo row in re_ItemregiView.Rows)
                {
                    //
                }

 

The gridview data sorted by clicking on the Gridview header. the data from the source above will have the same content but in a different order.

I want to get an ordered sequence of data on the source.

Hi

When the combined width occupied by rowheaders and columnheaders is less than the width of the container of pivotgrid, horizontal scrollbar appears on the screen.

But when the row headers alone occupy width more than the width of the container of pivotgrid, horizontal scrollbar does not appear. Enabling autoscroll on the container of pivotgrid does not help in this case.

hi

im using 

design a radMultiComboBox with 3 column(two column is visible) and one column to select "ValueMember". use the below code for "filtering" :

 

every thing work perfectly, but in my project, when user type the name that not in DB, the application show the messagebox and open new form to add item into database.

when user press enter, this code should be work, but radmulticolumncombobox.Text property, is null (" "). while must be show what's user typed in combobox.

for example, in radmulticolumncombobox.Datasource, these exist : john,david,oliver , and user input : jason => radmulticolumncombobox.Text should be = "jason", but it's null.

I read many of the posts here on how to properly set BeginEdit to programmatically set a cell into Edit mode. However, the code is not working for me.

Here is the code I am using:

It does not work under these circumstances:
1) The second time the code is called.
I have the code in an Add button, so when the user clicks Add to add a new row, the 3rd cell is automatically opened for edit. This works the first time I click the Add button. But if I press it a second time, it does not work. I tried to call EndEdit before this code, and that did not help.

2) If the cell is a drop down list.
If the cell to automatically open for edit is a drop down list, the code does not work. It does not show the comboBox editor.

Any tips for fixing either of these issues is appreciated!

thanks!
