Hi,
We are using WHDG 10.2 ( 2010 ). Using SQL Datasources, and WebHierarchicalDataSources on page. I have two grids on the page one with three levels and one with two. The grids themselves work reasonably well, but whenever I have to do anything which requires postack in an update panel, the grids of course rebind this can take several seconds up to 4/5 which is not acceptable.
I read somwhere that 10.3 Is faster, but I have two questions on that.
1.) Are they really faster and is it likely to help in my scenario
2.) I dont want to have to reload everything. If I do load 10.3 can I then run two versions side by side ?
Lastly. Are there any other tips I could try to improve this. Other than that everything seems to work ok.
Thank you Alex.
I have posted a specific example of this as a new case. Tsvetlina is working on it. Thank you for your post.
Regards
Hello soberly,
Please let me know if you need any further assistance with this matter.
Thank you for choosing Infragistics.
Thank you for posting on Infragistics forum.
I will try to give you some information that I believe will be helpful. But first, let me answer your questions:
1. Yes, there are some improvement in 10.3 version of the controls. It’s not easy to measure how much, but if you are interested, you can open and check our Whitepaper report about WebDataGrid performance here - http://ko.infragistics.com/innovations/performance-whitepapers.aspx.
2. It’s highly recommended to use only one version of the controls at the same time to avoid unwanted issues. New versions of the controls provide better functionality and performance and have most of the issues of the old ones corrected. You can easy upgrade your projects by using “Version Utility” tool installed in your Infragistics directory. Step by step guide for upgrading you can find here - http://help.infragistics.com/Help/NetAdvantage/ASPNET/2010.3/CLR4.0/html/Web_Using_Version_Upgrade_Utility.html . If you want to use two versions side by side anyway, you can use “BindingRedirect” element (it’s not recommended!). More information about it you can read here - http://msdn.microsoft.com/en-us/library/eftw1fys.aspx
Important property that you may try to use, if you want less communication with the SQL server, is “EnableDataViewState” Property of the WebHierarchicalDataGrid. This property can (if set to “true”) reduce data load on postback. You can read more information about that property here - http://help.infragistics.com/Help/NetAdvantage/ASPNET/2010.3/CLR4.0/html/WebDataGrid_Getting_Started_with_WebDataGrid_EnableDataViewState_Property.html
