have a gridview which has a delete linkbutton in 1 column, problem is that the click event for the button is not firing at all, the page does postback but the breakpoint wont execute and jump in the click event at all.
[Code]....
When my page is first loaded i receive error message stating to the effect
cant find Email for GetInvoicesByVendor.
this refers to a function in another class file:
Public Shared Function GetInvoicesByVendor(ByVal Email As String, ByVal vendorid As Integer) _
As IEnumerable
yet i only want to execute this function during the button click event and not when page is first loaded with the following parameters:
vendorid.Text = 1
txtcustomerid.Text = test@yahoo.co.uk
My objectdatasource is declared as follows:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
OldValuesParameterFormatString="original_{0}"
SelectMethod="GetInvoicesByVendor" TypeName="InvoiceDB">
<SelectParameters>
<asp:ControlParameter ControlID="txtcustomerid" Name="Email"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="vendorid" Name="vendorid" PropertyName="Text"
Type="Int32" />
</SelectParameters>
</asp:ObjectDataSource>

I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.
View 5 Replieshow can go to next page in gridview without refresh page
i thing programmers says wihtout postback?
I design a page which contains one dropdownlist, gridview1 and gridview2. All of them extract data from the same table (a SqlDataSource). The Gridview1 is used to edit, update data with edit, update and cancel button. My problems are:
1. After update gridview1, the dropdownlist and gridview2 don't update data.
2.After updata gridview1, the gridview1 resets to its original state if refresh page.

I ahve displayed a group of data in my gridvew with the edit option linkbutton template field for each row. The gridview columns consist of employee name and projectname and total hours field employee worked.
So in this when i click the edit button using the datakeynames alue for project name id and employee id ,i have to redirect the page to another page with the values in the grid for the particular employee.so that i can update the totalhours field in the redirected page.and if i press the update button in that page then the page should be redirected to the gridview page with the updated value for the particular employee and project. The page which should be redirected consist of project name dropdownlist, module field,date field and total hours field. No employee name field.
Using the gridview rowdatabound field i have postbacked the url page with the project name id but it does not displays the project in the redirected page.And employee name i have to redirect with the session value i think?
I am using datalist and used custom paging for that but on page index changed there is full postback..because i am sending the values through querystring just have a look to this link
[URL]
i want to remove this postback...
I have a abc.aspx page having some control like (drop downs, text boxes), i am filling a grid based on selected items in the drop downs and date selected from the ajax calender extender control attached to the from data and to date text boxes.
Inside grid there is a link which redirects to bcd.aspx, this page (bcd.aspx) is having a back button to redirect abc.aspx.
Now what i want is, abc.aspx should main its state like grid, drop downs and text boxes should be shown as it was earlier, i.e. all should have same values as it was at the time of redirecting to bcd.aspx.
Yes, there is a way to maintain the state by passing all values from query string and than get all values back and rebind all controls. But i don't want to go this way because i will have pass so many values in query string.
How can I use postbackurl with a formview in master detail after I insert an item in the formview which is at the bottom of a big page? The master detail is inside a tab container
View 1 RepliesI am debugging an ASP.Net C# application in Visual Studio 2010, the application is running and execution is currently stopped at a breakpoint. How can I stop the page execution without "Terminate All" or killing the debugging process altogether, similar to what would happen if an unhandled exception was thrown? The "Break All Cntl+Alt+Break" option is grayed out in the Debug menu.
I want to stop the app from running but not have to go through a compile/start again. EDIT: I want execution to stop, not break, so that the page finishes loading and I don't continue running the application from the breakpoint forward. I've looked through the Breakpoints panel, the Debug menu and have right clicked all over but still haven't found the right option.
Ive got on my aspx page button with code:

Is it possible to execute javascipt before postback and if result is true then do postback and go to method save_click and if not just ignore it ?
So I have an ASP.Net web forms application that is using URL Routing. It works great on the old single server shared web hosting account. It has been moved over to a new platform that appears to be a web farm. When a postback happens it now just refreshes the page and the event handler is not envoked. Another thing I've noticed is they put the application into a sub-folder on the account and are using ISAPI Rewrite to point the domain to the sub folder.how to get the postback to execute on this web farm?

View 6 RepliesBasically I want to get some javascript to be sent back to the client and executed from a postback inside an UpdatePanel. Furthermore this is inside of a reusable WebControl. I've tried
this.Page.ClientScript.RegisterStartupScript and this.Page.ClientScript.RegisterClientScriptBlock but Firebug shows that those scripts aren't sent back in the postback's response.
I also tried straight up writing a <script> tag inside the control's main div in the Render method, which does get sent back but isn't executed. I got a hacky solution working, but ideally looking for a cleaner solution. The hack is to add a 1x1 pixel img with width/height set to 0 and use that for an onload event to execute the script and that works, but it seems like there has to be a cleaner way to do this.
I am having a gridview in which there are many columns. The Last column is button column with command name as Select.
In row command event, I am creating a webreqest instance and passing the url of the required page in my application, and based on the response status code, updating the column value for that particular row.
This is working.
What I want is this should be asynchronous. Means, if I click the first row Select button, then it should fire and process request. Meanwhile I should be able to click other row's Select button, even if the previous button's click event is still in process.
Means the communication should be asynchronous. Even if
I need to execute a javascript function when a row of a datagrid is clicked. I am not sure how to do this.
I have tried adding a template column with a button
<asp:TemplateColumn>
<ItemTemplate>
<asp:Button
ID="myButton"
Text="Insert
collection"
OnClientClick="putData();"
runat="server"
/>
</ItemTemplate>
</asp:TemplateColumn>
And then attaching the javascript to it:
myButton.Attributes.Add("onclick",
"putData()")
But it produces an error.
I need to run a stored procedure from an aspx page but because it takes a long time to complete, it times out at MyDataAdapter.Fill. This sp doesn't return any recordset but the number of records affected would be nice.
Protected Sub BtnProcessDT_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnProcessDT.Click
Dim DS As DataSet
Dim MyConnection As SqlConnection
Dim MyDataAdapter As SqlDataAdapter
MyConnection = New Global.System.Data.SqlClient.SqlConnection
MyConnection.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("RevConnectionString").ConnectionString
MyDataAdapter = New SqlDataAdapter("uspINSERTDT", MyConnection)
MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure
MyDataAdapter.SelectCommand.Parameters.Add(New SqlParameter("@RowCount", SqlDbType.Int, 4))
MyDataAdapter.SelectCommand.Parameters("@RowCount").Direction = ParameterDirection.Output
DS = New DataSet() 'Create a new DataSet to hold the records.
MyDataAdapter.Fill(DS, "RowCount") 'Fill the DataSet with the rows returned.
Basic syntax of the stored procedure.
It SELECTS a single record (at a time) from a table, processes the data and UPDATES four other tables.
ALTER PROCEDURE [dbo_DHT].[uspINSERTDT] (@RowCount INT OUTPUT)
AS
BEGIN
select @RowCount=@@ROWCOUNT
END
Do I need to create a DataSet if all I want to do is capture the number of records? How do I increase the timeout? This is strictly an intranet web application used by one person so performance isn't a big priority. Editing the sp to reduce the amount of time to process isn't practical due to the amount of processing that occurs.
