I'm using one WebHierarchicalDataGrid on my page. When page is postback around 5-6 times, I am getting below mentioned error:
----------------------Begin-------------------------------------
[IndexOutOfRangeException: Index was outside the bounds of the array.] Infragistics.Web.UI.GridControls.GridBot.LoadClientCollections(Object[] collections) +2165 Infragistics.Web.UI.Framework.RunBot.LoadClientData() +43 Infragistics.Web.UI.Framework.RunBot.HandleLoadPostData(String postDataKey, NameValueCollection postCollection) +25 Infragistics.Web.UI.GridControls.ContainerGrid.LoadPostData(String postDataKey, NameValueCollection postCollection) +80 System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) +1068 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3406
----------------------End-------------------------------------
I'm wondering if this error occurs because my WebHierarchicalDataGrid is too big, or are there any possibilities to cause this problem?
Below is the code defination:

Hello Abishek,
In order to investigate this matter in more detail, a working sample illustrating the issue in practice and the product version used would be greatly appreciated. There seem to be no issues in the provided code, however please note that calling Rows.Clear() on each page load should not be necessary.
Please do not hesitate to contact me with any questions and updates regarding this matter.
