Forms Data Controls :: GridViewRow Control Manipulation?

Jan 14, 2010

My head aches from beating it against the wall for so long. I have a gridview that is populated from a code behind table. The gridview has 3 bound lables, a checkbox (unbound) and another label (unbound). All fields are in template fields. I have coded a vb sub with one command: beep. It fires perfectly every time a user checks the gridview ckeckbox. Here are the columns of the gridview:

1. Player - bound label

2. Description- bound label

3. Amount- bound label

4. ToPay - ckeckbox

5. AmountToPay - unbound label

When a gridviewrow's checkbox is checked (or unchecked) the code determines the check status. If it is checked then the AmountToPay label is to display the same value of the third label (Amount) or it will clear it's text value if the checkbox is unchecking the box. Here is my code:

The gridview:

[Code]....

Here is the vb code that does beep():

[Code]....

I have tried about a dozen ways of reading the checked property of the checkbox but nothing works (sender, e, gridview, rows, items, cells, findcontrol, adnauseum). I want to work the code like this somehow:

If row.Checkbox.checkproperty=true then
set lblToBePaid.Text = the lblAmount.Text
Else
lblToBePaid.Text = ""
EndIf

Forms Data Controls :: GridViewRow Generate Custom ID?

Nov 22, 2010

I would like that ID of subcontrol generated from the GridViewRow (NamingContainer) be named including database unique ID.

Exemple :

Suppose in the first colum of my GridView I have a Label displaying the name of an item fetch from a database table.

SQL Database table definition

SQLTable

- UniqueID
- Name

In this table I have the following records

- 1956 Hello
- 3013 World
- ... ...

Suppose I have a GridView having a label (id="lbName") in the first column template.

Now I'm binding GridView using this query : SELECT UniqueID, Name FROM SQLTable

After binding, the HTML result will be :

myGridView_ctl101_lbName

But I would like that NamingContainer names sub items like this :

myGridView_ctl1956_lbName

So I have tried in the RowDataBound event of the GridView : e.Row.NamingContainer.ID = (DataRowView)e.Row.DataItem)["UniqueID"].ToString()At first look it output exactly what I need but after that I can't get working Edit mode, it seem to break DataKeys or something else.

Jul 9, 2010

I want to change the value of a literal within a repeater ItemTemplate after postback, based on a value detected at postback.I can't render the whole repeater again though I think because it's actually a radio button in the control that inititates the postback and so I need that control / value to be persisted.

Forms Data Controls :: Erase Values In All Controls In A GridViewRow?

Mar 30, 2010

Is there an easier way to erase the data from all controls in a gridviewrow than my current approach (code below)?

The problem: When a new type of control is added to the grid, like a radiobutton, it would not get handled here without adding to the code. The tests for type of control can get long and monotonous.

The solution I am seeking: Test the control once for "is WebControl". If it is a web control, cast it and call a single command that would erase its data. Does such a concept exist in ASP.NET 2.0/C#? I know I can do other things on the WebControl level, like set backcolor, but would like to do the same for erasing data.

foreach(Control c in row.Controls)

{
if(c is TextBox)
{
TextBox tb = (TextBox)c;
tb.Text = string.Empty;
}
elseif(c is CheckBox)
{
CheckBox cbx = (CheckBox)c;
cbx.Checked = false;
}
elseif(c is DropDownList)
{
DropDownList dd = (DropDownList)c;
dd.ClearSelection();
}
}

Forms Data Controls :: Gridview Change One Field And Cause Change In Another?

Mar 7, 2011

I have a gridview in which I have several editable fields. The user wants a non-editable field to be modified if another field is modified in the same row. e.g. if Age>=65, Status should ="Retired"

I am using the following demo: [URL]

to create a bulk edit gridview so some columns are automatically editable and others aren't, with a single update button. I can set Status="Retired" in the xml generated, or as a rule in database table. But I'd like the status field in the gridview to change when Age is modified and to be shown to user before they press the single Update button. I'm using update panels and ajax on the page also.
