I downloaded the code and when the gridview loads it works; however, when I select the next gridview index page, the gridview is blank.  Don't know why it is not working like it should.

Forms Data Controls :: Listview Control Paging Preserving The State?

Aug 31, 2010

I have a question regarding the listview control paging and preserving the state of the items on page change.

I am using listview control and datapager control to achieve paging in the listview control.

I use the listview to display list of questions like with radiobutton list options as answers...

I am unable to preserve the selection of answers between the page changes..

for eg : I If select option1 for the question1 and move to a next page. and If I come back to previous page, the selection goes.

I tried using the view state...but could get this working..

Forms Data Controls :: How To Keep The Textboxes Values And Checkboxes Selected During GridView Paging

Aug 12, 2010

I have Grid view control in the page. Enable paging option is true.

Columns in the Grid view are ID, Name, Checked and Email

Whenever user selects the check box then I am showing txtEmail in the Email columns so that I can enter email id in the textbox.

Like this I am selecting checkboxes and entering values in the txtEmail when I go to next page and comes back. Then these entered values are cleared.

How to keep the textboxes values and checkboxes selected during paging?

C# - Uncheck Checkboxes In GridView With Paging

Dec 30, 2010

I have an ASP .NET GridView with Paging. One column in it has a CheckBox. In a certain scenario, I want to uncheck the checkboxes that are checked.

foreach (GridViewRow dr in gvMyGridView.Rows)
{
if (dr.RowType == DataControlRowType.DataRow)
{
if ((CheckBox)dr.FindControl("chkIsApplicable") != null)
{
((CheckBox)dr.FindControl("chkIsApplicable")).Checked = false;
}
}
}

But unfortunately because of Paging only the records that are currently shown in the Grid can be accessed in this way. I want it to apply to ALL the items in the GridView. This should happen client side and when the user commits will get saved to the database.

Forms Data Controls :: Preserving Selected Row On Gridview And Datalist On Postback?

Jan 12, 2010

I have a GridView and a DataList on the same page in a father/son relationship.I am trying to have the selected row on the GridView be in 'focus' on postback so if a person toward the bottom of the list is selected then the scroll position is maintained.I am trying to do the same with a DataList too.Heres my javascript.

[Code]....

and I have this around the GridView :

[Code]....

and this around the DataList:

[Code]....

The funny thing about this code is when I comment out the DataList portion, the GridView scroll postition works, when I comment out the GridView javascript portion the DataList scroll postion works.Is there a special way to make sure both of these can work or is it a javascript issue?

Forms Data Controls :: GridView Sorting, Paging And DataBinding / When Control Causes A Postback GridView Is No Longer Sorted?

Jan 10, 2011

I'm trying to extend the GridView control to enable sorting and paging for any situation.

When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?

To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.

Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.

My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.

The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,

[Code]....

I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.

Forms Data Controls :: Paging In Gridview Control Asp.net 2.0, MySQL

Feb 20, 2010

I am a new user of ASP.NET 2.0 (VB.NET)
I am facing a problem related to GridView Control

I have a table <UsersDetail> with following structure in MySQL

FIELDNAME | DATATYPE
---------------------------------------
userid | Numeric
Userlogin | Varchar(25)
Userpassword | Varchar(25)
Firstname | Varchar(50)
Lastname | Varchar(50)
---------------------------------------

I wrote a code to fetch data from this table :

Dim Con As New MySqlConnection
Dim Cmd As New MySqlCommand
Dim Adp As New MySqlDataAdapter
Dim DTable As DataTable
Con.ConnectionString = ConfigurationManager.ConnectionStrings("dbConString").ConnectionString
Cmd.CommandType = CommandType.StoredProcedure
Cmd.CommandText = "sp_FetchAllUsers"
Cmd.Connection = Con
Adp = New MySqlDataAdapter
Adp.SelectCommand = Cmd
DTable = New DataTable
Adp.Fill(DTable)
GridView1.DataSource = DTable
GridView1.DataBind()

Basically Gridview controls is used to display data in tabular format.
but due to requirement I changed its layout to columner in following manner

<asp:GridView ID="myGridView" runat="server" AutoGenerateColumns="false" AllowPaging="True" PageSize="3" Width="520px">
<Columns>
<asp:TemplateField HeaderText="User ID">
<ItemTemplate>
<asp:Label ID="Label3" Text='<%#Eval("userid") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="User Login">
<ItemTemplate>
<asp:Label ID="Label4" Text='<%#Eval("Userlogin") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Pack Amount">
<ItemTemplate>
<asp:Label ID="Password" Text='<%#Eval("Userpassword") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="For">
<ItemTemplate>
<asp:Label ID="First name" Text='<%#Eval("Firstname") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Validity">
<ItemTemplate>
<asp:Label ID="Last name" Text='<%#Eval("Lastname") %> Months' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

Now come to the problem, i set the AllowPaging="True" and page size to 3 records/page but when click on paging links it displays the following error :

The GridView 'myGridView' fired event PageIndexChanging which wasn't handled.

Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Web Forms :: Preserving State Of LoadOnDemand TreeView In MasterPage (VB.NET)

Jun 25, 2010

I have an asp:TreeView in my MasterPage, which is loaded on demand from a database using some custom functions to fill the Tree. My tree will only ever be 4 levels deep (root -> 1st sublevel -> 2nd sublevel -> leaf nodes) What I want to achieve is preserving the expand/collapse state of this TreeView while navigating between different aspx pages, that all share the MasterPage holding my TreeView. I have been using the methods described in these resources:

[URL]

but I am still not getting the results I want... My TreeView markup in the MasterPage looks like this:

[Code]....

I am using a custom class to save and retrieve the state of the TreeView, the code is pasted below:

[Code]....

In my Page_Load on MasterPage I have:

[Code]....

where Reload() makes sure I'm loading the TreeView for the correct argument (based on a user selection)
And in TreeView_Unload I have:

[Code]....

With all this in place, my TreeView is behaving almost as I want it.. I can expand the root node, it will be populated and I can browse to a new content page and have the same treeview appear in the MasterPage (with same expanded root)... BUT if I try to expand any of the 1st sublevel nodes, I end up with a completely collapsed treeview instead. After some debugging I have come to the conclusion that the "NodeExpanded" event gets the ROOT NODE as event argument instead of the 1st sublevel node that I clicked. When the user changes the option that makes the TreeView re-populate with new data, I simply do a "HttpContext.Current.Session("TreeViewState") = Nothing" to reset my saved state.

If you need more info / code snippets, let me know and I will post it.. But I felt there was no reason to post my complete source, as I have multiple files with about 500 lines of code each (there's a lot happening on the MasterPage, other than the TreeView)

C# - Adding User Control To Page Programmatically While Preserving Controls Already Present

Mar 25, 2011

I am trying to add a user control into a div at runtime. I can add the control no probelem but it overwrites the previous control added.Basically, I am trying to add passengers to a travel system - the passenger details are in the user control and I don't know in advance how many there will be. I have an add new passenger button which should append the new user control into the div without overwriting the previous passenger. The code is c#/.net 4. I have tried to save the control data into viewstate and re add it with the new one but that also doesn't work. Here is a snippet of the code I'm using

foreach (Control uc in p_passengers.Controls) {
Passenger p = uc as Passenger;
if (p != null) {
p.SaveValues();
}
}

however, p.SaveAs() (just writes the control values into ViewState) is never hit.

Forms Data Controls :: Checkboxes In Gridview Not Getting Registered?

Jun 3, 2010

I hav a prob of checkboxes' checks not being registered...as explained below :

I have a gridview which is being populated using datasets.

[Code]....

I have added a column of checkboxes it using a TemplateField

[Code]....

And I am using a button to count the number of checked checkboxes.

[Code]....

I am viewing the value of session variable under at check.aspx

The Problem is that no matter how many checkboxes I check they are always counted as 0. The 'check' just doesnt get regsitered in the gridview.

After quite certain testing, a few things are clear

The checkboxes are being discovered by the counting loop fine.If I mark a cell as checked in the dataset before binding, then that check does get registered and thus is counted. Any thing I am missing ? Do i have to update something ?
