Hi Telerik support,

IWhen using drag-drop in the treeview, there is an auto expand behaviour to be able to move a node inside another. Currently, the time required on a node to exapand it is very short. Is it possible to modify this time to expand the node only after a longer time.

I found a post to disable this behaviour (http://www.telerik.com/community/forums/winforms/treeview/prevent-auto-expand-of-nodes-during-drag-and-drop.aspx) but not to modify the delay.

Thanks.

I was working on summary totals of the columns in the gridview and successfully got them at the end of the gridview.

The problem I am facing is the font of the summary column is too small to read properly. I have set the theme as breeze and also seen with other themes and without theme also but it's the same as small(doesn't change). Is there any way to increase the font size and to set the font family(Arial), background color/foreground color.

Also if possible, the alignment of the summary totals. 

All my grid data is looking too god but the only think what is lacking behind is the summary column. I have just recently bought the telerik premium controls(Q3 2009 SP 1).

Please see attached file for more understanding and reference.

Anyone help here will be appreciable. Thanks in advance.

Cheers,

 I have a gridview with the datasource set to a bindinglist.  My goal is for the gridview to accurately reflect changes in the bindinglist’s composition (specifically additions at this point).  When I add objects to the bindinglist I get an error saying “Bounds cannot be changed while locked”.   I believe this is an issue with the Gridview because if I do not set the datasource, the bindinglist is populated as expected.  After a lot of searching I came across a few other posts which were similar to my situation:

• Updating Problem  -http://www.telerik.com/community/forums/winforms/gridview/updating-problem.aspx
• Updating bindinglist from seperate thread -http://www.telerik.com/community/forums/winforms/gridview/updating-bindinglist-from-seperate-thread.aspx

However these deal with updating data already present in the bindinglist.  My application starts with an empty bindinglist set as the datasource and is populated through code.

 

My C# .Net 3.5  winforms program uses multiple threads to search through all the directories on the machine and return files that meet certain criteria.   The recursive search creates a new thread for each directory found to iterate over it's files:

These files are used to create objects which are stored in a custom collection object which inherits from System.Collections.ObjectModel.Collection<T>.  I’ve created an event that fires when an object is added to the collection and subscribe to it in my form.  The arguments for the event include the object being added to the collection, so in the event handler I add the object to the bindinglist:

//form field variable used as the datasource for the gridview.

BindingList<MyFileObj> bindingList = new BindingList<MyFileObj>();

 

MyCollectionChangedEventHandler(MyEventArgs e)

{

  bindingList.Add( (MyFileObj) e.GetMyFileObj);

}

When that didn’t work I modified the program to use a backgroundworker and queue hoping that putting the code in the WorkerCompleted method would force it to all execute on the UI thread:

 

Both of these methods of updating the bindinglist result in the same error.

How can I get my changes to the bindinglist to not crash my program when it is set as a datasource? Preferably, without sacrificing the speed gained through multithreading.   

Thanks for any help you can provide. 

Hi everyone ,

thank you in advance
sorry for my english

how do i get a TimePicker to take a null value?  not the datetime picker, just the time one.  i have the date one working.

i tried setting it to null

timSatStart.Value = null;

and it didn't work, i also tried binding a nullable datetime from the database to it and it won't work either.

both ways set the time picker to the current time.

thanks.

Hi,
i use LineSeries to display temperature history over time. Because of big data, I would like to build up a DrillDown ChartView where the first view should be categorized by "MMM yyyy" and when I click on each data point I will drill down to "dd/MM/yyyy". However it seems to be that the radChartView1_Drill event wasn't fired when I click on data point.

My question is: How can I make a Drilldown effect for LineSeries Chartview?

I attach below my first view categorized by "MMM yyy"

My code snippet is

Hello,

I am using "RadDateTimePicker" for choosing only time. The issues is that when i change the hour in the "RadDateTimePicker" control,
the time automatically changes from PM To AM. Suppose the Time shown is "6:44:33 PM", Now if i select "6" (hour) and type 1 using keyboard, the PM part of date automatically changes to AM. Below is the code regarding how i have declare the RadDatetimePicker.

this.radDateTimePicker1.Culture = new System.Globalization.CultureInfo("en-CA");
this.radDateTimePicker1.Format = System.Windows.Forms.DateTimePickerFormat.Time;
            this.radDateTimePicker1.Location = new System.Drawing.Point(135, 176);
            this.radDateTimePicker1.MaxDate = new System.DateTime(9998, 12, 31, 0, 0, 0, 0);
            this.radDateTimePicker1.MinDate = new System.DateTime(2000, 12, 31, 0, 0, 0, 0);
            this.radDateTimePicker1.Name = "radDateTimePicker1";
            this.radDateTimePicker1.NullableValue = new System.DateTime(2012, 9, 11, 9, 28, 9, 125);
            this.radDateTimePicker1.NullDate = new System.DateTime(((long)(0)));
            this.radDateTimePicker1.ShowUpDown = true;
            this.radDateTimePicker1.Size = new System.Drawing.Size(138, 20);
            this.radDateTimePicker1.TabIndex = 93;
            this.radDateTimePicker1.TabStop = false;
            this.radDateTimePicker1.Text = "radDateTimePicker1";
            this.radDateTimePicker1.Value = new System.DateTime(2012, 9, 11, 9, 28, 9, 125);

I'm using a radgridview to display search results for metadata for files. The grid has 6 columns and for any search I try, whenever I'm adding results to the grid, the whole UI is freezing until the results are added.

I've tried it with a background worker and adding the rows in the report progress event., but it still doing this.

The grid is placed on a tabpage control.

Hi All,

I'm looking for a way to create a gallery as show in the attached image. The screenshot isn't from a Telerik Ribbonbar, but from an other component. Is there a way to get this result with a Telerik RadRibbonbar?

I haven't seen any of this in the demo files.

greetings
