I have a button to Save data as well. In this Save routine, I simply look at the value of the ViewState to determine which button the user clicked, because that determines which code I should process. This used to work but is no longer working.
When user upload new documents then this document goes for approval to supervisor and for this i use dropdowns ...when I use dropdown the exact result not occur and now i wat to approve/reject through checkboxes...
I have changed the look and feel of the grid by modifying the cols, rows in the gridview. I need to save this in the gridview viewsate, so that it load the modified look and feel next time it loads from the viewsate.
I want to be able to select rows and save them for later display. I wish to store the data in a session object for viewing before i decide to save permanent in database.
At my user-control I populate listbox with collection and want save data in viewstatecontrolstate for further autopostback using.
protected void btFind_Click(object sender, EventArgs e) { var accounts = new AccountWrapper[2]; accounts[0] = new AccountWrapper { Id = 1, Name = "1" }; [code]...
ListBox is populated at button click. When I save accounts to ViewState listBox is empty, when not it displays collection good.
i bind a DataTable to a gridview.i want to use the DataTable in some postback event, and ii want to use viewstate. does gridview save data in viewstate? if no what is the best way to do this.
(full story :i have a custom gridview derived from standard asp.net gridview, and i put a button in header to export data to excel, i want to use data saved in viewstate to export to excel)
I am looking for an event firing before a DropdownList auto-postback to save Listbox items (populated with JS) in the ViewState.I tried the OnSelectedIndexChanged event but it's fired too late.
I need some help in the technical approach with the following scenario:-
1) A dropdownlist with some options. It has a postback action on the selectedIndexChange server side event handler. For example, lets say it contains language options such as english, french etc.
2) Repeater with a label and the textbox control. For example label is Emp Name and textbox is containing the Emp Designation. We have to save emp designation in the various languages.
3) Every time i pick something from the dropdown, i have to flip the textbox control and fill the form. Now i want to save the given data of the texbox in the viewstate. So that every time, the user changes the dropdown selection, he can see the repeater data corresponding to the dropdown selection.
4) I guess some kind of relationship between the dropdown option and the repeater data is needed. But how can we make this thing work.
Now which is the best technique to save the data on the server side? I have to keep it in the viewstate.
Background:I'm building a custom control as a base class that derives from CompositeControl. It consists of a FormView, a ObjectDataSource and a CRUD-Button Series (Create, Read, Update, Delete - Buttons). I'm loading the different FormView templates within the deriving classes dynamically from file with Page.LoadTemplate().
Class structure:
TabControlBase:CompositeControl
Employer:TabControlBase
Applicant:TabControlBase
Each deriving class knows the specific template-paths for loading FormViews templates.
The ObjectDataSource is connected with a DAL using a Select and an Update Method. The Select-Method works fine: When loading the CompositeControl the data of the DAL are shown in the Labels of the embedded FormView (ReadOnly-Template). When I'm switching to Edit Mode the data also are displayed in the TextBoxes (Edit-Template).
The problem occurs when I'm trying to update data using the "Save" - Button: The connected DAL-Method is calling properly, but the parameters all are NULL.Tree structure of this custom control:
All controls will be added dynamically in the base class "TabControlBase" within the overridden CreateChildControls - method. The CreateChildControls method is called by the deriving classes e.g. Employer after setting specific properties e.g. templates, object data source methods etc.The control is placed in a simple abc.aspx-Page. What I detected so far on PostBack
- When I'm looking at the ViewState Collection within the OnLoad-method of the abc.aspx the ViewState-Collection is Null (Count = 0)
- It seems that the control tree is empty. I'm not able to find any control using a proper working recursive FindControlMethod
- Only the Page.Request Collection shows the expected controls
Conclusion for now:It seems that the CompositeControl "forgets" the values of the FormView TextBoxes on PostBack. It seems it has to do with ViewState Management.

We have an application process that consists of several web forms. If the user clicks to go back a step we would like to auto-populate the fields. I am assuming there is a common generic way to do this without having to mess with individual controls - what is it?
When I attempt to store the current time of 'DateTime.Now' in a column defined as time in a table within an SQL database, I get an error message that says: Cannot implicitly convert type 'System.DateTime' to 'System.Timespan'.
I have no trouble storing the current date of 'DateTime.Today' in a column defined as date, but this column will not also store time along with the date. The date column has properties that indicate it has a data and system type of date with a Length of 3 and a Numeric Precision of 10. The time column has properties that indicate it has a data and system type of time with a Length of 5, a Numeric Precision of 16 and a scale of 7. Did I define the time column incorrectly for storing the time of day?

I want to get data from the database and display it in gridview. The gridview should be editable. Meaning the user can add, edit and delete items/rows in the gridview. Everytime the user adds/updates/deletes an item, the gridview is also updated. However, these changes will only be saved to the database once the Save button is clicked.
