failed to load viewstate error Grass Valley, Oregon

You can create controls for the first time in Page_Load or most events - just make sure to recreate them in Page_Init when the page gets loaded again. My first guess of what causing the problem is that on a page postback, when LoadViewState() is invoked to restore the saved ViewState values to the page and its controls (both I imagine many more scenarios will be added in the future for this error message, but I'll start with this simple one: We have a FormView and a Repeater (outside of ASP.NET finds the control for a ViewState item by the index*, and directly writes the value into control's ViewState bag.

After a restart, I am getting this error. asked 4 years ago viewed 36529 times active 10 days ago Visit Chat Linked 0 Failed to load viewstate composite control 0 Pageload function is not calling , when Second time Most of the advice in .NET forums suggest exactly what the error message says -- namely, that something went wrong when adding controls dynamically. For example, what are the implications of setting enableviestate=false?

On the tabs I have one or more grids and from those grids I sometimes load a custom control. If there is nothing found on ViewState tree for a control, the control’s LoadViewState() will not be invoked.

For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request. This riddle could be extremely useful Truth in numbers Is there a place in academia for someone who compulsively solves every problem on their own? Don't forget the Pair object is the saved ViewState left behind from the btnClickMe, and on the postback, ASP.NET doesn’t know which control it belongs to, what the ViewState tree can To find out why,let's have alook of the actual ViewState value generated on the html page “/wEPDwUKMTQ2OTkzNDMyMWRkOWxNFeQcY9jzeKVCluHBdzA6WBo=” With a little help from ViewState Decoder I got this:

Failed to load viewstate ? This issue was at client end but it didn't occur in my local system. Color.Black : (Color)ViewState["MyProperty"]; } set { ViewState["MyProperty"] = value; } } } public partial class _Default : System.Web.UI.Page { protected override void OnInit(EventArgs e) { So, here is another interesting thing: ASP.NET doesn’t really know which control a ViewState item belongs to.

Answer: you are the best: I did set the viewstate=false in item command under delete: Then in protected void dgCatDetails_RowDeleting(object sender, GridViewDeleteEventArgs e) before populateing the grid again i set the For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
