Header cell image gets reset on mouse over

Hello,

I am using the RowFormatting event to set an image to the GridRowHeaderCellElement. This is working. However when a user hovers the mouse over the header cell, the image gets removed, and it will only get reset if he clicks a row again.

Here is the code I use for RowFormatting:

    
            void RowFormatting_ImageChanging(object sender, Telerik.WinControls.UI.RowFormattingEventArgs e) 
        
                    { 
        
                        GridRowHeaderCellElement grhce = e.RowElement.Children[0] as GridRowHeaderCellElement; 
        
                        if (grhce != null) 
        
                        { 
        
                            GridViewEditableEntry aa = e.RowElement.RowInfo.DataBoundItem as GridViewEditableEntry; 
        
                            if (aa != null) 
        
                            { 
        
                                if (aa.Changed) 
        
                                    grhce.Image = myimage1; 
        
                                else if (aa.IsEditable) 
        
                                    grhce.Image = myimage2; 
        
                                else if (!aa.IsEditable) 
        
                                    grhce.Image = myimage3; 
        
                            } 
        
                            else 
        
                            { 
        
                                grhce.Image = null; 
        
                            } 
        
                        } 
        
                    }

How can I prevent the header cell image to get reset?

Resetting RadGridView

Hi whenever I 'reset' a RadGridView to see the latest data, I get duplicate rows by filling again. My RadGridview is filled dynamically. An help would be appreciated.

If DBConn.ConnectionString <> "" Then

daDataAdapter =

New SqlDataAdapter(CurrentBeo.sCurrentSql, DBConn)

daDataAdapter.Fill(DSData, CurrentBeo.sTableToUpdate)

bsMaintenance.DataSource = DSData

bsMaintenance.DataMember = CurrentBeo.sTableToUpdate

grdMain.DataSource = bsMaintenance

bnMain.BindingSource = bsMaintenance

End If

Default filter problem

Hello experts!

I have a GridView, with a column that is filtered like this:

protected override void OnLoad(EventArgs e)
{
     base.OnLoad(e);
     ..............
     gridview1.DataSource = data;

     string fString = "filter";
     FilterExpression filter = new FilterExpression(FilterExpression.BinaryOperation.AND, GridKnownFunction.Contains, fString.ToString());
     gridview1.Columns["filtered_column"].Filter = filter;
     ...............
}

It works fine, but when I try to set the No Filter option to that column, it does nothing. It's supposed to show all the rows, but it still shows the filtered ones.

How I can solve this?

Thanks for your help!

ShapedForm: flickering

Hello experts!

I have a main window that is a shapedform, that uses panels, buttons, treeviews, etc ... all of them are your controls.

I also have a custom message box, that is a shapedform as well.

When the message box is closed all the application flickers, and you also can see the applications that are behind (messenger for example) for a short moment.

I've read a lot of information about flickering here. Is this solved? Any workaround?

Please help! The users are complaining about this disturbing behavior.

Cursor Focus on Filter when CellClick Event

Hi,

When a CellClick Event gets fired, I want to get the focus on the Filter of the Column where the user has clicked so that the user is able to directly type in Filter values.

How can I do that?

New rows not showing until another action done

Hello,

I have an app that creates grids programmatically and then populates them (in unbound mode) with data. However I don't actually see the rows displayed in the grids until I do some other activity. For example if I add another new row manually, or reorder columns, etc. then suddenly I will see all the previously added rows. I tried putting in a call to Refresh() for each grid when I was done adding rows but that didn't seem to help.

    
                    private void populateGroupFactControls() 
             
                    { 
             
                        var level2Grids = from fact in activeJob.FactSet 
             
                                          where fact.Level == 1 && fact.DataTypeDesc == p.factTypeGroup 
             
                                          select new 
             
                                                     { 
             
                                                         GridName = uiUtility.CreateFactGridName(fact.FactName), 
             
                                                         Rows = 
             
                                                              from childFact in activeJob.FactSet 
             
                                                              where childFact.Level == 2 && childFact.ParentFactID == fact.FactID 
             
                                                              join factValue in activeDataElement.Values 
             
                                                              on childFact.FactID equals factValue.FactID 
             
                                                              group factValue by factValue.GroupInstanceID 
             
                                                              into rowCells 
             
                                                              select new 
             
                                                                 { 
             
                                                                     RowID = rowCells.Key, 
             
                                                                     Cells = rowCells 
             
                                                                 } 
             
                                                     }; 
             
                        foreach(var grid in level2Grids) 
             
                        { 
             
                            var gridControl = (RadGridView) groupFactTable.Controls.Find(grid.GridName, true).First(); 
             
                            gridControl.Rows.Clear(); 
             
                            foreach(var row in grid.Rows) 
             
                            { 
             
                                GridViewRowInfo newRow = gridControl.Rows.AddNew(); 
             
                                newRow.Cells[p.RowID].Value = row.RowID; 
             
                                foreach(var cell in row.Cells) 
             
                                { 
             
                                    newRow.Cells[cell.FactID].Value = cell.InstanceValue; 
             
                                } 
             
                            } 
             
                            gridControl.Refresh(); // Doesn't seem to help 
             
                        } 
             
                        groupFactTable.Refresh(); // Doesn't seem to help either 
             
                    }

Another consideration is that the grids are all being held in a TableLayoutPanel control (groupFactTable in the above code sample). I also tried calling the Refresh method for that parent control but that didn't help either.

I'm using the Jan 2009 version (8.2.0.0) of the RadGridView. Any thoughts would be greatly appreciated.

Thanks!

NewRow(), Rows.Insert and not fired CellFormatting/RowFormatting Events

Hi,
I'm using the RadGridView to programmatically insert new rows at specific locations. To accomplish this I use the following code:

var rowIndex = someNumber;
var row = Grid.Rows.NewRow();
Grid.Rows.Insert(rowIndex, row);

Though the row is visibly inserted in the grid by the following code, neither the values assigned to the cells of this row are displayed (though the assignment doesn't throw any exceptions), nor are the defined CellFormatting or RowFormatting events of the grid are fired.

If I use the following code instead all events and assignments are fine:

var row = Grid.Rows.AddNew();

I need an insert and not and add.

Please advise.

Best regards,
Anton
