Editcontrol performance

[Ernie Obregon]

Syncfusion,

Using the new v4.4 Edit Control what are the parameters for best (fastest) performance? Currently I have the same parameters as I used with the v4.3 Edit Control and v4.3 was much faster, so I know I am missing something. Right now in v4.4 when I type text into the control the larger the file loaded the slower my typing is. I can type several words and then I have to wait for them to print (show up on screen) to the control. The smaller my loaded file the faster I can type with great results.

I have the following parameters set:
ConvertOnLoad = False
ParsingMode = PartialParsingNoFallback
GraphicsCompositingQuality = HighSpeed
GraphicsSmoothingMode = HighSpeed
Other graphic settings are set to Default or SystemDefault

My laptop has an Intel Core2 Duo processors, 1GB of ram and 256MB video card so I know it is not the computers performance that is slowing things down.

Hi Teamels,

Thanks for bringing this issue to our attention. I do see this problem here and have notified the development team in this regard. We have logged a bug report Defect# 3173 on this, and will try our very best to address the same at the earliest. You could track the progress of this bug fix at this link below :

Curious if there has been any progress on this Performance issue.
Also I noticed that when the EditControl is opened without any language configurations applied the control seems to be getting color information from some where?

On the very first line in the control no coloring takes place, but starting on the second line and so forth throughout the control numbers 0-9 are colored and some words also.

How can I disable this default configuration coloring the control?

thanks

Hi Teamels ,

Our apologies for the delayed response. I have requested our development team for a time frame for fixing Defect#3173 and will update you within a week. It is possible to disable the default coloring by setting the LoadConfigFile property to false. Let me know if this meets your requirements.

Thanks for your patience.

Yes, I do have the LoadConfigFile property set to false in the Designer and I also forced this by command in the FormLoad event.

Me.EditControl1.LoadConfigFile = False

however the default coloring is still present

Hi Teamels,

Our apologies for the delayed response. I have tested for this issue using a sample and was not able to see the problem. This is how I went about testing this issue :

1. Run the attached sample.

2. The numbers 0-9 on line 12 are not colored.

Please let me know if I am missing something.

Thanks for your patience.

Yes, your project does as you say, however on my sample project attached with the same settings as far as I can tell the default coloring does not go away. Please let me know what I am missing.

My sample is done with VB 2005 Express

Hi Teamels,

It is possible to disable the default coloring using the configuration file. I have attached a sample that illustrates this. Let me know if this meets your requirements.

Thanks for your patience.

Yes, this does work, thank you

Can you please tell me when the 100% CPU utilization performance issues will be worked out. I have about 2 weeks before we make a decision and I have quite a bit of work already done using this control so far and I really like the ease of use.

Thanks

Just checking the status of the 100% CPU utilization performance issues. It has been seven days since I posted this.

If this is not the appropriate place for this post please redirect me.

We are eager to know
Thanks

You use regex a lot in the edit component. Do you set RegexOptions.Compile? Can we configure this?

That is a tradeoff for performance vs. loadtime.

Hi David,

Our apologies for the delayed response. The EditControl uses RegexOptions.Compiled internally. I am afraid, it is not possible to configure this. We have considered this as a feature request and will notify you when the feature has been implemented.

Thank you for your patience.
