I have a treeview control with Checkboxes, when 1 is checked/unchecked I would like to run some code, but for some reason nothing is being raised when I click on the checkbox. If this were a datagrid I'd be looking for the autopostback="true", but this control doesn't appear to have anything like that.

I have a datagrid in aspx page.Inside of datagrid i am using around 15 controls such as Button,dropdownlist and text box
controls.Once the datagrid binds then the events in the aspx page not firing.Issue occured when the number of rows greater than 500.The number of rows less then its works fine.

I have some data which contains angle brackets in some of the fields.Even if properly escaped as <: or > (or even the hex codes), or contained in CDATA, in Visual Studio 2005 ASP.Net, the field data is being truncated at the first angle bracket. If I replace the data with curly braces, it displays fine.Is this a parser defect in the TreeView control? I can use Response.Write and see that the data provided by the XmlDataSource is fine. Example:
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
This truncates right after TT Description. If I change to curly braces or parentheses, it displays fine.

When I click the button image residing in footer template i just posts back and don't go to the itemcommand event.
I've put a simple gridview on my Asp.net webpage. I've configured the fields via C# code:
gvMainDataGrid.AutoGenerateColumns = false;
gvMainDataGrid.AutoGenerateDeleteButton = false;
BoundField bfldSeqNmbr = new BoundField();
bfldSeqNmbr.DataField = "PKSequenceNmbr";
bfldSeqNmbr.Visible = false;
gvMainDataGrid.Columns.Add(bfldSeqNmbr);
BoundField bfldEmployeeCode = new BoundField();
bfldEmployeeCode.DataField = "Employee Code";
bfldEmployeeCode.HeaderText = "Employee Code";
gvMainDataGrid.Columns.Add(bfldEmployeeCode);
BoundField bfldProjectCode = new BoundField();
bfldProjectCode.DataField = "Project Code";
bfldProjectCode.HeaderText = "Project Code";
gvMainDataGrid.Columns.Add(bfldProjectCode);
BoundField bfldProcessCode = new BoundField();
bfldProcessCode.DataField = "Process Code";
bfldProcessCode.HeaderText = "Process Code";
gvMainDataGrid.Columns.Add(bfldProcessCode);
BoundField bfldActivityDate = new BoundField();
bfldActivityDate.DataField = "Date";
bfldActivityDate.HeaderText = "Date";
gvMainDataGrid.Columns.Add(bfldActivityDate);
BoundField bfldActivityHours = new BoundField();
bfldActivityHours.DataField = "Activity Hours";
bfldActivityHours.HeaderText = "Activity Hours";
gvMainDataGrid.Columns.Add(bfldActivityHours);
CommandField cfldDeleteButton = new CommandField();
cfldDeleteButton.ShowDeleteButton = true;
gvMainDataGrid.Columns.Add(cfldDeleteButton);
It's data source is a Dataset retrieved from a webservice. Here is the C#code to bind the data to the gridview
Service1 MyService = new Service1();
dsMainData = MyService.GetData(strIdNumber);
gvMainDataGrid.DataSource = dsMainData;
gvMainDataGrid.DataBind();
It retrieves great. No problems at all. Then, when I actually try to use the delete button, I get an error that the RowDeleting event is not being handled. I thought that was pretty explicit, so I created the event:
private void gvMainDataGrid_RowDeleting(Object sender, GridViewDeletedEventArgs e)
{
return;
}
Well.....that didn't work. So, I thought that maybe I needed to configure it via the actual aspx file. So, I changed
<asp:GridView ID="gvMainDataGrid" runat="server">
</asp:GridView>
to this:
<asp:GridView ID="gvMainDataGrid" runat="server" ondeleting="gvMainDataGrid_RowDeleting">
</asp:GridView>
But, no avail. I've scoured the web and tried so many combinations of capital letters and whatnot -- but no effect.
i wrote the following code to perfrom the inline deletion of datagrid elements.

the row deleted event is not firing and the row deleting event is firing twice. why is is happening?

This gets called when I go into Insert mode just fine, but it also gets called when I click the INSERT button to insert my record. I am trying to use this function to set default values for those controls on the form.
How do I stop this from being fired twice, or is there another method of setting the defualt calues?
The <ItemTemplate> loads properly, and the line:
<asp:LinkButton ID="generalcomments" OnClick="SetPage_N_of_All" runat="server" PostBackUrl=<%#DataBinder.Eval(Container.DataItem, "Filename")%>> <%#DataBinder.Eval(Container.DataItem, "Title")%></asp:LinkButton>
loads the page correctly, BUT it does not fire the onClick event (OnClick="SetPage_N_of_All").
The method SetPage_N_of_All is in the codebehind page and is as follows:
public void SetPage_N_of_All(object sender, EventArgs e)

ContentPlaceHolder mpContentPlaceHolder;
TextBox mpTextBox;
mpTextBox = (TextBox)this.Master.FindControl("page_N_of_All.Text");

I have a problem with listview and I can't find any useful solution.
Here is my situation:
I have a listview with insert row and i need to do some calculations as user types in. Some fields are not filled by user but computed by javascript function (they are not inserted into db, they are shown for informational purposes only). These fields are just textboxes - computed ones are disabled. So i want to add some javascript functions to handle the computation, but i need this functions to have proper IDs. So i add them dynamically on listview.itemcreated with attributes.add. And that's where the problem begins.
If I use textbox.attributes.add("onblur", "some code"), suddenly all row commands of insert row stop working. They seem to cause a postback (all filled fields are blank after) but they are not firing any event. ItemCommand, ItemInserted, ItemInserting... Nothing. I have a masterpage and updatepanel in my website but i don't think that is the source of all problems. If I clear all javascript events from all textboxes and dropdownlists, row commands are working again. But I really need some client side computation and validation and I don't know how to make it work and still can insert rows.
