Hi Experts,
GOOd Morning,
This is regarding view state and hidden field in asp.net
I have storing information in viewstate["strInfo"]="hello world" in page1
my doubt is can i get access to viewstate["strInfo"] in another page? if not pls give clarification.
i read in some book Hidden field can post information to another page. If it is yes Why can't viewstate it is also stored in hidden field only
Pls give clarification asap.
Thanks in Advance

If it's urgent, please use "Session" or "Cache" instead of ViewState.
I dont think that ViewState can be accessd from another page. cuz the ViewState is stored in the hidden field by using algorithm. so, if you are going to another page, the value of this hiddenfield wont be avaliable in another page.
so, maybe. you can use Session. eg: Session("a") = "Hello World!"

Hi,
Even though ViewState information is stored in a hidden field (__VIEWSTATE) in the page, you need to remember that the information is in encrypted state. Also the information is page specific, so if you try to access some other page's ViewState information in some other page only, then you won't be able to retrieve any value.
"On all page visits, during the save view state stage the Page class gathers the collective view state for all of the controls in its control hierarchy and serializes the state to a base-64 encoded string. (This is the string that is emitted in the hidden __VIEWSTATE form field.) Similarly, on postbacks, the load view state stage needs to deserialize the persisted view state data, and update the pertinent controls in the control hierarchy."
I hope that answers your nice question
Thanks and best regards

ViewState is for a single page.

I'm having another problem. My dataGrid has three different columns. two of them are supposed to be for inserting data and before I inserted the radiobuttonlist it was inserting data very well but after inserting the radiobuttonlist my datagrid cannot insert data any more why isit so? To insert I was using The edit,Update and delete column.
Thanks.

Hi All,
I am facing some problem in GridView Paging. Below is the code, I have written in my code behind. (ASP.NET 2.0 and VB.NET)
I have set the 'AllowPaging' property of Gridview to true. Pagers are Displayed at the bottom. But when I am trying to navigate between the pages, Paging in not working. Only the First Page is always Displayed.
How can I solve this? pls guide me. Thanks
Dim ds As DataSet
Protected Sub displayData()
'Dataset if Poulated
gridView.DataSource=ds.Tables(0)
gridView.DataBind()
End Sub
Protected Sub gridView_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvChangeStatus.PageIndexChanging
gridView.PageIndex = e.NewPageIndex
End Sub
Regards,
Jay

Hi,
Inside the Protected Sub gridView_PageIndexChanging, alongwith setting the newpageindex, you will also need to bind the grid again.. because thats the step where each and every row of the grid gets bound with new data.
Thanks and best regards

I want to show the number of rows in a datatable. I'm still a bit new, but thought there would be something similar to Items.Count that returned the total items/rows in the table. I'm looking to do this in C#. thanks!
|
|
|
|
|
This should do it:
DataTable.Rows.Count;
Ben
|
|
|
|

Use the datatable.count method. Add it after you filled the datatable.
Dim rwCount as string = DataTableName.Rows.Count.toString()
