Example. I need to manually call the test_RowDataBound event.

I tried this as I've used with buttons in the past.
button1_click(this, EventArgs())
but it dosen't work
I've got a GridView control with LinkButtons in different cells. Currently when someone clicks a link, it fires the ItemCommand passing the CommandName and the ID of the item the link is bound to. That all works fine. I need to modify it now to not use links anymore. It now needs to show a popup balloon with a link (styled to look like a button) and when the link is clicked, I want it to do the exact same thing. I'm sure there are several ways of doing this, but for time's and consistency's sake, I'm copying the method used from another page we have that is already doing this. It has a hidden DIV on the page with the link in it. When you hover over a link, javascript repositions the div and makes it visible.
So what I need to do is pass my CommandName and item ID to the javascript so that it can trigger the postback when they click that single link. I know this is not the only way to get to the end result, but what I want to do if possible, is still fire the GridView's ItemCommand and set he DataListCommandEventArgs' CommandName and CommandArgument properties. Can someone explain how, under normal circumstances, clicking the LinkButton in the GridView fires the ItemCommand? I know that the LinkButton's click event is forwarded to the GridView but what gets sent from the client side that let's the server know the link was clicked?
I have a gridview, I would like to call an event gridview rowdatabound on button click, but in gridview are edittemplate that uses textbox.
Is when I can call event RowDataBound on button click, edittemplate value in gridview can calculate?
here's my code
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) {
decimal d1 = 0, d1e = 0, d2e = 0, d3e = 0, d4e = 0, d5e = 0, d6e = 0, d7e = 0, d8e = 0;
decimal d1f = 0, d2f = 0, d3f = 0, d4f = 0, d5f = 0, d6f = 0, d7f = 0, d8f = 0;
decimal tv = 0;
decimal harga = 0;
decimal totalval = 0;

I have a gridview with data. I want a button which is not part of the gridview. Then if I press a button the gridview is sorted by two colums. i.e column1 ascending column2 descending.
I am not looking to work with a Sqldatasource as I use a data access layer. So the sort would have to be from a datatable and databind or directly with the gridview.
I want to insert an extra row in the gridview in the RowDataBound event (or another place if thats possible). How can I do that?
The data in the row to be inserted is not part of the resultset, but rather to split the gridview in logical sections.
I don't want to databind a gridview, I want to be able to add rows myself within c# code. I can see there is a GridViewRow object and wondered if I can use this to add/remove rows as required?

I have a gridview that I am manually binding in my code behind page because I have to pull out information from other sources for the WHERE clause.The issue is that I get an error on the aspx page that one of the columns is not in the dataview, however when I run the SQL statement in SQL all the columns are there and there is not a spelling error.If I remove the column from the gridview then the page loads.I cannot see why the column is a problem.Here is my ASPX gridview code.
[Code...]
This is the line where the error occurs. <asp:Label ID="Label2" runat="server" Text='<%# Bind("date_submitted") %>'></asp:Label> Here is the code behind
[Code...]
Here is the ending SQL statement that works in SQL and does return the date_submitted column. SELECT id, title, date_submitted, (SELECT username FROM users WHERE (id = t.submitted_by_user_id)) AS submitted_by, (SELECT name FROM departments WHERE (id = t.department_id)) AS department FROM tickets AS t WHERE (closed_by_user_id IS NULL) AND (department_id = 48 OR t.department_id = 83) ORDER BY t.date_submitted DESC
Can you add a row of data programatically and bind it to the gridview? If so, how?
I have a grid with 2 columns. One of these columns is a template that runs a function and delivers an output. Within that function I need to manually add data that is not present in the sqldatasource to the grid and use it when performing aggregate functions.
ColumnA - ColumnB
1 - MyFunction(1) - adds new row (1, B)and returns A to column B.
2 - MyFunction(2) - May return just A
Grid should look like
1 - A
1 - B
2 - A
Even though SQLDataSource only returns
1 - AB
2 - A
how to edit data in grid view manually without auto generate in gridview + ajax.
View 4 RepliesI have a need to call Oracle stored procs to populate a gridview. I'm able to call one stored proc to get the column header text and another one to get the corresponding data. Currently I'm using a datareader, but I want my gridview to have sorting and paging enabled, so likely I'll need to read the data into a datatable and then bind the gridview to it.I've never had to manually configure a gridview - usually just use autoformatting.1. Do I essentially set up the columns manually in the gridview since it has no data to go off of in design mode? I'm guessing most of these will be Bound fields. A few of my columns are going to display date values that need to be formatted a certain way
and one column will be a link that needs to call a second method to populate a different grid. I'm not sure what the syntax for this is.
I have a GridView with bound columns, for which I am manually setting the ItemWidth and HeaderWidth to 500px, and nothing happens. Is there some trick to getting this to work?
This is a column a large amount of text in it, and it keeps sizing to the width of the header text, which is simply "note". I don't want to set Wrap to false, becuase then the colummn could be thousands of px wide in cases.
I'm a new developer here, working in VB. Have a question that is stumping me as well as some others.
I have a gridview control built. I am not using an <sqldatasource> tag, so I can't use it's autoGenerateSelect/Update/Delete functionality. I have built a template field that has an "edit" link button in it, and by clicking it will fire the grdName_SelectedIndexChanged event of the gridview.
Now, it's in this event where I'm having trouble. I have it coded so that when this event fires, it will build a textbox and button control. Code:
Protected Sub grdResults2_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdResults2.SelectedIndexChanged
Dim row As GridViewRow = grdResults2.SelectedRow
Dim cell As TableCell = row.Cells(6)
Dim txtSeq As New TextBox
Dim btnUpdate As New Button
'build the textbox in the Search_Seq cell
txtSeq.ID = "txtSeq"
txtSeq.Width = Unit.Pixel(20)
txtSeq.Text = row.Cells(6).Text
cell.Controls.Add(txtSeq)
'build the "update" button in the Search_Seq cell
btnUpdate.ID = "btnUpdate"
btnUpdate.Text = "Update"
cell.Controls.Add(btnUpdate)
End Sub
So the textbox and button populate perfectly. I can run it in the browser and it works fine.
How do I go about setting up the event for this button now? Because it's being manually built here in the gridview event, there is no button for me to "double_click" on in the design view to auto-build this event. There are some properties that need to be set on this button to link it up to a new event....and that's where I'm lost.
Hopefully I don't leave any additional information out.
I have tried a few different ways to add columns of data to a gridview. I have just about got success, except for I am having problems with only getting the last value in my array of data to insert into the gridview column. For example if I return 4 rows from an sql query, with the values of 2, 4, 6, 8. The last value (8) shows in all for rows of the gridview for that particular column.

At the moment, nothing is happening when I click on the column headings. I ran it in debugging mode in Visual Studio and put a breakpoint on the Sorting event handler. I noticed that the variable dtSortTable is empty even after the TryCast(VacanciesGV.DataSource, DataTable). If I hover over this statement in debugging, it shows the data from the file system, so it does appear to be reading it.
I have a grid with edit link.
when user clicks onedit link , i want to show modal popup extender which displays text boxes for editing those data.
when user finishes editing the grid should again updated.
I have a SQL table containing a timestamp column. This table is displayed in ASP using GridView control. The timestamp column is indicated in the DataKeyNames property of the GridView. I'm using TemplateFields for all columns and a ItemTemplate HiddenField control connected to the timestamp column using Eval.
<asp:TemplateField
ItemStyle-Wrap="false"
Visible="false"
HeaderText="timestamp"
SortExpression="timestamp">
<ItemTemplate>
<asp:HiddenField
ID="gv_hid_timestamp"
runat="server"
Value='<%#
Eval("timestamp") %>'
></asp:HiddenField>
</ItemTemplate>
</asp:TemplateField>
The data is displayed properly. I'm trying implement the optimistic concurrency in C# using the value of above mentioned timestamp and a stored procedure. The SQL stored procedure expects the @timestamp as varbinary(8). I'm not sure how to pass the value of gv_hid_timestamp back to the stored procedure. I'm using the following:
command.Parameters.Add("@timestamp", SqlDbType.Binary).Value = Byte.Parse(((HiddenField)gv.Rows[row].FindControl("gv_hid_timestamp")).Value);
resulting in the following error: "Input string was not in correct format." (I also tried different data types but with similar result). I want to be able to pass this parameter programmatically from C# and not have to specify it on the UpdateParameters list.

And the relevant code:

What does work: I do see the right info if the formview is shown but when I click on the Update button it just doesnt fire the corresponding itemupdating event.
Can someone see what is wrong or missing?
What do I want to archieve: Just update the subscription's credits and its type: Upgrade, Prolong.
-edit-
New finding: I added 'onitemcommand="fvSubscriptionEdit_ItemCommand"' to the formview and a corresponding event method with a simple code that throw a exception(just testing) but it doesnt enter the method but does whine when the method is missing. So why does it whine if the method is not there but doesnt enter the method if it does exist? I presume that this is the same problem.
