I have a FormView and I have the following defined:
[Code]....
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?
I have a DataGrid which i am using on the page alogn with 4 tabs. Clicking on each tab different datasource is getting bing to the data grid. Now following is problem,
There are 4 tabs of UI I have written code to bind data source to data grid on onclick event of tab (which is linkbutton) However when i am clicking on the tab data gets bind to data grid but item created and item databound event which i have attached to grid on page init() are not firing on the first time.
I also have attached page index changed event clicking on which executes item created and item data bound event
ASP.NET 3.5I'm very confused. After inserting a record into a formview, I want to go back to readonly mode. However I need to enable a button in the ItemTemplate as well.I put my code in the ItemCreated event (tried ModeChanged event as well) as below:
If formview.currentmode = FormViewMode.ReadOnly and inprocess then
ormView.Row.FindControl("NextImageButton").Visible = True
end if
Although currentmode is ReadOnly, FormView.Row still seems to contain the EditItemTemplate (combined template for inserts and edits) controls, not the Itemtemplate controls. This seems totally wrong to me - can someone confirm?
I got a formview which has a textbox control, when I tab to the next box, OnTextChanged doesn't fire.
aspx page:
Following code is in <InsertItemTemplate> in FormView
<asp:TextBox ID="txtPhone" runat="server"
AutoPostBack="true"
OnTextChanged="txtPhone_TextChanged">
code behind:
protected void txtPhone_TextChanged(object sender, EventArgs e)
{
....
TextBox Phone = (TextBox)fv.FindControl("txtPhone");TextBox
....
}
Up till the moment I can not understand why the "SqlDataSource_NewAccount_Inserting" event of the formview's SqlDataSource is not firing!
The code inside the event handler is not executed, even the debugger does not stop on break points inside the "SqlDataSource_NewAccount_Inserting" function!
Here is my code:

I am using VS2010 and target .NET Framework 3.5.
I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
I have a nested formview. I need to set a value for a textbox when I'm in insert mode from parent formview which is editmode.
View 4 RepliesI have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminserted event?
View 2 RepliesI have a telerik grid bound to a Linq data object, however, I limit the fields returned:
<IQueryable>filter = data.Select(x => new {x.ID, x.Name, x.Age});
I would like to access these fields in the ItemCreated method of the grid:
protected void rgPeople_ItemCreated(object sender, GridItemEventArgs e)
{
Telerik.Web.UI.GridDataItem item = (GridDataItem)e.Item;
?????? Person = (???????)e.Item.DataItem;
}
What do I declare ?? as so that I can use:
String ID = Person.ID;
String Name = Person.Name; etc
I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack)
{
//Initialize SetupDate to today.
TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate");
setupdate.Text = DateTime.Now.ToShortDateString();
}
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.

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?

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:

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.
