View 4 RepliesDataset Manually Put Into The Viewstate Of A Web UserControl Not Kept After Postback
Feb 2, 2010I've created a Web User Control that is placed on the page at design time. It's purpose is to pop up with a grid of items the user is to choose from. So I've got a gridview on it. And this code in the usercontrol:
Public Property DataTable() As Data.DataTable
Get
If Not IsNothing(ViewState("_SelectGridDataTable")) Then
Return ViewState("_SelectGridDataTable")
Else
Return Nothing
End If
End Get
Set(ByVal value As Data.DataTable)
ViewState("_SelectGridDataTable") = value
End Set
End Property
So when the user clicks on a button on the page, I put this in the code on the page:
SelectGrid2.DataTable = GetContacts().Tables(0)
SelectGrid2.Show()
And this works fine. The grid pops up (using jQuery) and the grid is shown. The problem is, that when the user clicks the "OK" button on the UserControl, the ViewState("_SelectGridDataTable") is always nothing. And I don't get it, since it's in the viewstate.. ?!? So does viewstate here not REALLY mean viewstate?
Forms Data Controls :: GridViewRow Control Manipulation?
Jan 14, 2010My 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

View 2 RepliesForms Data Controls :: GridViewRow Generate Custom ID?
Nov 22, 2010I 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.

Forms Data Controls :: Erase Values In All Controls In A GridViewRow?
Mar 30, 2010Is 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();
}
}

Iis6 - Dynamically Adding Controls - Viewstate Is Not Retained After 20 Minutes?
Dec 3, 2010We have a ASP.net form [.NET 3.5 on IIS 6] that loads controls dynamically. We are able to retain the values in the viewstate as long as the postback happens within 20 minutes. The database also gets updated properly. Everything works as expected.
However, If it takes more than 20 minutes for a user to fill out the form, the controls no longer retain their values during postbacks. The session values are intact, the user authentication is also intact. We tried several things
1) Added machine keys to web.config files - we have 2 web servers load balanced by Windows load balancer
2) We confirmed that the user are routed to the same server - because the sessions are sticky
3) Increased the session timeout to 60 minutes in IIS 6.0
4) Increased the Idle timeout for connection pool to 60 minutes
5) Changed Form authentication ticket timeout to 60 minutes

Forms Data Controls :: ObjectDataSourceView.BuildDataObject Throwing IndexOutOfRangeException?
Jan 27, 2010I've got a FormView bound to an ObjectDataSource. The FormView/ODS selects and displays my data correctly but when I change the data and try to update,nothing (seemingly) happens.Stepping through the code and digging deeper into the stack trace and output window,I figured out that the following sequence of events happens:
- The ObjectDataSource drills down to System.Web.UI.WebControls.ObjectDataSourceView.BuildDataObject to create the object I specified in the "DataObjectTypeName" property
[code]...
- Here is where the IndexOutOfRangeException happens. Sometimes one or two of the data object's properties will be set, sometimes none. Either way, the exception is thrown and the sequence is stopped (the business object's update is never called).
- The exception is not thrown inside any of the properties' set methods.I'm assuming that the exception is happening when BuildDataObject is using Reflection to find my data object's properties (GetProperty() etc.. ). Since I can't see the source code of BuildDataObject and the debugger won't give me any more information, there is no way for me to see which property (if any) is causing this.I double checked the names and types of all 27 of the data object's properties.

Forms Data Controls :: DataView Throwing Exception - Index Out Of Range
Jul 13, 2010A dataview is throwing an out of range exception when a page submit button is clicked. The strange part is if you change the data in the dataview by selecting a different person in the DDL the page works fine. Its only when the page loads and the default person in the DDL is when the DataView throws the exception.
The exception is thrown on the last line when I add DV.Rows(0).Cells(1).Text to the id_num parameter. I know there is a value in the dataview because it is displayed on the page. I can refresh the dataview with another person's information and the code works fine. This really has me confused. Here is a bit of the code behind.
