State Management :: Datagrid Values Not Being Retained?

Jan 6, 2011

In a aspx page I am displaying records in the datagrid control. I have added one more column to the datagrid in my aspx page and this column is the template column which contains the checkbox control for each of the records. Then I have two buttons a) Display and b) submit

When i click Display button I get all the records in the datagrid from the database(about 700 rows). Then when I click the checkbox for a few rows and click the Submit button then it redirects to another aspx page (i have given response.redirect) . But sometimes when i click a few rows and then click the submit button the screen goes completely blank and it even does not redirect to the next page as specified(in the browser URL the initial page name is only shown).

If I refresh the page after that then datagrid shows the updated value.

{
string newData;
TextBox aTextBox;
aTextBox = (TextBox)(e.Item.Cells[0].Controls[0]);
newData = aTextBox.Text;

Forms Data Controls :: Capturing SelectedIndex Values From Datagrid To Populate A Datasource?

Jan 18, 2011

I'm trying to populate a datasource for a dropdownlist (which is actually in an insertitem template field within a detailsview on the same page) with a selectedvalue from a gridview. When I select a row in my Gridview 1, I get the "no value for a required parameter" message.

Forms Data Controls :: Dynamically Binding Dataset Table Values To Datagrid's Header Column?

Jun 29, 2010

I want to dynamically bind dataset values into datagrid's header datafield.

Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.

i.e like ds.Tables[0].Rows[0][0].

Is it possible to do it in Datagrid ItemDataBound function like,

e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]

or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

Forms Data Controls :: How To DataGrid SelectIndex Inside A DataGrid

Sep 22, 2010

Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.

[URL]

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.

I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.

How To Store Additional Values In Html Table Row And Hide Values From Display

Jun 28, 2010

I would like to store some business flags (like: isFavorite, isOnLive etc.) per an html table row that won't be visible to user.

In practice, I have a simple ADO.Net DataTable on my code-behind which is used as a data-source for a asp.Net GridView control.

This table contains some business flags on its 0th, 1st, 2nd columns.

I need to store those columns on the rendered HTML of the grid-view -so that I can reach them via JavaScript- but I do not want them to be visible.

Linq To Sql - MVC2 - Set ViewModel Values With Retrieved From Db Object's Values With DataAnnotations

Jan 8, 2011

Prior to using a ViewModel, I could easily pass the "soon to be edited" object directly to the view without needing to fuss over setting individual properties etc as the View conveniently accepted the Employee type directly..

[HttpGet]
public ActionResult EditEmployee(int? id)
{
EmployeeRepository ER = new EmployeeRepository();
Employee SomeEmployee = ER.GetEmployee(id.Value);
if(SomeEmployee!=null)
return View(SomeEmployee);

But now I'm using a ViewModel with DataAnnotations attributes applied over the top of various properties for validation purposes. Which creates a problem.. After fetching the "soon to be edited" object from the db, setting the ViewModel's values is suddenly a whole lot more complicated. I can't simply pass the retrieved object straight to the view, as the View now expects the VMEmployee type instead. I would like to be able to do something like:

[HttpGet]
public ActionResult EditEmployee(int? id)
{
EmployeeRepository ER = new EmployeeRepository();
Employee SomeEmployee = ER.GetEmployee(id.Value);
if(SomeEmployee!=null)
return View(new VMEmployee(SomeEmployee));

All paths seem to lead to a huge constructor which manually sets the values of each individual property. But I never had to do that before when I wasn't using a ViewModel. Model binding was a blessing! My objects also have complex child objects, which my form is also collecting values for, so this would be a huge/verbose task against DRY principals. I don't even really want to use a ViewModel, but am forced to because I need two different DataAnnotations rule sets for different validation scenarios applied to the same object.

All I want to do is be able to have two different DataAnnotations rule sets for different scenarios. I.e. public-facing www site vs internal-facing admin site. DataAnnotations doesn't seem to be flexible enough to easily cater for this common need. I've tried AutoMapper, but it throws an error saying it can't map my object types, I suspect because Employee was auto-generated by LINQ to SQL. What is the most elegant way to achieve this while sticking to DRY principals?
