[Solved] Expression Based Conditional Formatting on Child Rows

Hi,

I have conditional formatting rules on a parent grid that are defined as expression types

New ExpressionFormattingObject ("COL1",Expression:="COL2 = 1", etc.)

The compare data is in a different column than the formatting. This works OK for the Grid.MasterTemplate.Columns.

I also have identical rules defined for Grid.MasterTemplate.Templates(0).Columns, however the styling does not get applied for these rows on the child grid. If I change the child rules to be ConditionalFormattingObject type as:

New ConditionalFormattingObject ("COL1", Equals, Value:="1", etc.)

the styles are applied correctly. I can't do this though as the data item is in a different column than the formatting. (test against COL1, style COL2)

Is there something I need to do to get the expression rules to format correctly?

Many thanks,

Mark.

RadProgress bar fails to update.

I'm not understanding why it fails to update in another thread correctly if the process is running fast. Example

If I do this, this will freeze the progress bar until its completed. It will get to a certain spot then stop.

radProgressBar2.Maximum = 1500;

for (var i = 1; i < 1500; i++)

{

var p = i;

radProgressBar2.Value1 = p;

Thread.Sleep((int)numericUpDown1.Value);

}

radProgressBar2.Value1 = 0;

radProgressBar2.Text = "Task Completed!";

If i do this

radProgressBar1.Maximum = 1500;

for (var i = 1; i < 1500; i++)

{

var p = i;

radProgressBar1.SafeInvoke(() => radProgressBar1.Value1 = p, false);

Thread.Sleep((int) numericUpDown1.Value);

}

using a custom invoke it works just fine. I dont understand why it doesnt work correctly with the build in feature. This is also happening on the status progress bar as well.. Here is a quick app source.

Also it seems to work with the built in features using Win7 or above, Its freezing on windows xp sp3

Edit: Never mind i can not attach rar, or .zip to this thread.

Uploading a video to demonstrate.

Orphaned GridViewTemplate

In my properties window I see two GridViewTemplates:

GridViewTemplate1
GridViewTemplate2

GridViewTemplate2 is not associated with either RadGridView controlsI have on the page. Is there a way to delete this orphaned GridViewTemplate without going into the designer.vb code (I only do that as a last resort)?

Thanks.

GridViewComboBoxColumn out of focus when scrolling

Hi,

I'm using Telerik.WinControls.GridView version 2012.1.321.20.
I have a GridView with a GridViewComboBoxColumn, and the problem I have is that when the box is open and I click on the scroll square- than it's like the focus is out and the comboBox is closed (it's like freezing for 2 seconds and than closing...).

Also, I'm using the next definitions, as you recommended before:

public class CustomDropDownListEditor : RadDropDownListEditor

{

protected override RadElement CreateEditorElement()

{

return new CustomDropDownListEditorElement();

}

public class CustomDropDownListEditorElement : RadDropDownListEditorElement

{

protected override RadPopupControlBase CreatePopupForm()

{

this.Popup = new CustomDropDownPopupForm(this);

this.Popup.VerticalAlignmentCorrectionMode = AlignmentCorrectionMode.SnapToOuterEdges;

this.Popup.SizingMode = this.DropDownSizingMode;

this.Popup.Height = this.DropDownHeight;

this.Popup.HorizontalAlignmentCorrectionMode = AlignmentCorrectionMode.Smooth;

this.Popup.RightToLeft = this.RightToLeft ? System.Windows.Forms.RightToLeft.Yes : System.Windows.Forms.RightToLeft.Inherit;

this.WirePopupFormEvents(this.Popup);

return Popup;

}

public class CustomDropDownPopupForm : DropDownPopupForm

{

public CustomDropDownPopupForm(RadDropDownListElement owner): base(owner) {}

public override string ThemeClassName

{

get { return typeof(DropDownPopupForm).FullName; }

set {}

}

public override void ClosePopup(PopupCloseInfo info)

{

base.ClosePopup(info);

if (info.CloseReason == RadPopupCloseReason.Keyboard)

{

((RadGridView)this.OwnerElement.ElementTree.Control).EndEdit();

}

protected override void OnMouseUp(MouseEventArgs e)

{

base.OnMouseUp(e);

((RadGridView)this.OwnerElement.ElementTree.Control).EndEdit();

}

You should handle the EditorRequired event to replace the editor:

void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)

{

if (e.EditorType == typeof(RadDropDownListEditor))

{

e.EditorType = typeof(CustomDropDownListEditor);

}

What should I do in order to not loose the focus when click on scrolling? I need the user to scroll up/doun and choose another option from the list.

I'm attaching an image of my comboBox.

Thanks,
Hila.

Rad DateTimePicker - Invalid Date Format Exception

Hello,

I use a Rad DateTimePicker in a certain application. What I want to achieve is to get the date that the user selects, along with the time of course, and send those using JScript to an asmx webservice as one of its arguments. What I did was that I sent the datetime as string from the JScript file and in the webservice I tried to parse that string back to datetime format using convert.todatetime method and I tried several other conversion methods but my problem was always one; and that is the string that's being sent is not recognized as a correct "convertible" datetime.

I debugged, and it's always sent as, for example, "2012-12-13-08-02-05" [this corresponds to 13/12/2012 08:02:05]. As you can see, this string really is not in one of the acceptable formats that the parsing methods accept.

I tried to change the input dateformat of the datetimepicker and it does change but only in displaying; it does not change in the string according to what I want [I mean the format I set is reflected on display only and not on save].

I'd really appreciate your help, thank you.

using linq to dynamic create chartview series

For those who might want to use this, I have created a quick sample on how to use linq to create dynamic series for chartview:

Example is created in VS2010 / VB.NET

Make sure you import:
System.Data.DataSetExtensions.dll
to use linq.

Me.RadChartView1.ShowLegend = True

Me.RadChartView1.ShowTitle = True

Me.RadChartView1.Title = "Sold products per country"

Dim graphSeries As New DataTable()

graphSeries.Columns.Add("Category", GetType(String))

graphSeries.Columns.Add("Value", GetType(Integer))

graphSeries.Columns.Add("XValue", GetType(String))

graphSeries.Rows.Add("Netherlands", 10, "2011")

graphSeries.Rows.Add("USA", 12, "2011")

graphSeries.Rows.Add("Germany", 7, "2011")

graphSeries.Rows.Add("Netherlands", 25, "2012")

graphSeries.Rows.Add("USA", 40, "2012")
