I am rebinding a Hierarchical radgrid after closing a custom edit/insert form using the below code and javascript. I would like to reset the state of the Grid as it was when the user clicked to edit a record. Currently all childgrids close up to the master. The attached images show what I mean. EditDetailRecord.png is where I want the user to be after the Rebind(). AfterDataRebind.png is currently what they see.

protected void Page_Load(object sender, EventArgs e)
{
    RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);
    manager.ClientEvents.OnRequestStart = "onRequestStart";
    manager.AjaxSettings.AddAjaxSetting(manager, this.__rejectedBatchesRadGrid);
    manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(Manager_AjaxRequest);  
 
    if (!IsPostBack) {  }
}
 
protected void Manager_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
    this.__rejectedBatchesRadGrid.MasterTableView.SortExpressions.Clear();
    this.__rejectedBatchesRadGrid.MasterTableView.GroupByExpressions.Clear();
    this.__rejectedBatchesRadGrid.Rebind();
}

Hi Tim,

Note that when calling RadGrid Rebind method the grid loses all its data associated with expanded items and items in edit mode. However, you could go through the Retain expanded/selected state in hierarchy on rebind forum thread for information how you could implement persisting state after rebind.

I finally had a chance to get back to this and the sample project at the link you provided did solve the objective. Thanks again.
