Data Controls :: Edit Each Row Independently In Form

May 7, 2015

I have a near full functioning form. 

I simply need to edit each row independantly. However upon applying the Edit, Update Cancel I get the following. 

I suspect this is because I am using the GUI and this will require some code per column?

Error[HttpException (0x80004005): The GridView 'GridView1' fired event RowEditing which wasn't handled.]   System.Web.UI.WebControls.GridView.OnRowEditing(GridViewEditEventArgs e) +1610245   System.Web.UI.WebControls.GridView.HandleEdit(Int32 rowIndex) +43   System.Web.UI.WebControls.GridView.HandleEvent(EventArgs e, Boolean causesValidation, String validationGroup) +611   System.Web.UI.WebControls.GridView.RaisePostBackEvent(String eventArgument) +205

Forms Data Controls :: Applying Changes To A Text Box Within A Form (edit Mode)

Sep 28, 2010

I'm using the free text editor [URL] and set a property (DesignModeCSS) to the text box based on the theme being used at the time. The following code works just fine:

TextBox_Home.DesignModeCss = "App_Themes/" + GetCurrentTheme() + "/BackOfficeTextStyles.css";

What I've since done is to add the text box control into a FormView (edit mode), and I'm now not sure how to access the text control to apply the code above.

Forms Data Controls :: Master Detailed GridView Edit Selects The Wrong Row To Edit?

Mar 16, 2011

I have a page with 2 GridViews on it. The top GridView shows all the Bike Riders the bottom GridView shows all the Bike Lockers. I have set up both GridViews to be able to Edit the data. And the top GridView to Select.

When I click the Select buton on the top GridView I programically reset the DataSource for the bottom GridView to show the Locker for the Biker of the top GridView Selected.

So far everything works great. I select a Biker on the Top GridView and the Bottom GridView resets just showing one record for the bike locker.

The problem is that if I then click on the Edit button on the bottom GridView (The Bike Locker GridView) the GridView goes into the Edit Mode but it now shows all the Bike Locker records and the edit record is always the top record of the GrdView.

Here is my code Behind:

Can The Value And Text Properties Of A Dropdown List Be Used Independently

Mar 8, 2011

Can these two properties of a dropdown list in ASP.NET be used independently?

I wanted to retrieve a null value when the user selects some text; I couldn't as it retrieves the Text property whenever the Value is null. Eg:

l1 = new ListItem("Cat", null);
Console.WriteLine(l1.Value);

The output is

Cat

In another situation, when both the properties have different strings, I get the string in the Value property when I use the Text property. Eg:

l2 = new ListItem("Cat", "Mouse");
DropDownList ddl = new DropDownList();
ddl.Items.Add(li);
ddl.SelectedIndex = 0;
Console.WriteLine(ddl.SelectedValue);
Console.WriteLine(ddl.Text);

The output is

Mouse

Use Same Form For Add And Edit When Specifying Html Attributes?

Dec 2, 2010

I wish to use the same form for adding and editing records within a database using a partial view. I understand that this is fine as the standard Html.BeginForm automatically output the correct html depending on the action that is being used (Add / Edit). However, I need to out said form with some extra HTML attributes. There does not appear to be an overload that allows this to happen without also specifying the ACTION and CONTROLLER names. If I hardcode these then surely I cant use the same form for edit and add automatically? Or am I missing something?
