Forms Data Controls :: Adding Gridview Row Getting An Error In The Browser?
Jul 24, 2010
I have a dynamic gridview which adds row when the button is click. But I am getting an error in the browser. I managed to run this and get it working but after couple of days working, there's a wierd error occur when I click the add row button.
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation
Here's my gridview
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" ShowFooter="True" BackColor="White" BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Horizontal" Height="288px" Width="512px">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# count() %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Question" >

The SQL works fine if I just query in SQL - I only get the error when I try to get anything from the SalesPerson table and display it in my gridview.

Currently I'm using the following code:

As of today my gridview is no longer showing when I run it in my browser. I have made changes to the database recently but the code behind and aspx file remains the same. No errors are coming up. Just the gridview is now blank and it was working perfectly shortly before.
<asp:GridView ID="grdFixtures" runat="server" AutoGenerateColumns="False"
DataSourceID="FixturesDataSource" OnRowCommand="PushMatchID"
DataKeyNames="MatchID">
<Columns>
<asp:ButtonField ButtonType=Button CommandName=StartMatch HeaderText="Match Scoring" Text="Start" />

I am trying to add a new row into a gridview but for some reason i'm having a problem in the for loop.
Directly goes to dtCurrentTable.Rows.Add(drCurrentRow) and of course, have an error "'row' argument cannot be null.
Parameter name: row", because the dtcurrentTable.NewRow was not executed.
Why is this happening?

Very new to C# although I have alot of older coding experience. Not much object orientated programming though. Anyways, I have a .net program I'm working on, basically to work on my skills although it will prove to be useful. I am keeping track of my work schedule. Currently, I am populating a datagridview from a sql 2008 express db. My columns are: date worked, hours, paid, and paidon. What I want to do is add an empty row whenever the date corresponds to a date that is "Monday". My goal is to line break every week. So that each work week (Mon-Sun) is seperated by a blank row. I would rather not actually have this blank row in the database. I would like the gridview to do this on the fly. Here is my gridview code in my default.aspx file:

<asp:GridView
ID="grvSchedule"
runat="server"
CellPadding="3"
CellSpacing="1"
SkinID="GridView_Regular" Width="732px">
<Columns>
<asp:TemplateField......

grvSchedule.Rows[j].Cells[0].Text = Convert.ToString(dTable.Rows[i]["PatientId"]);
grvSchedule.Rows[j].Cells[2].Text = Convert.ToString(dTable.Rows[i]["Name"]);
grvSchedule.Rows[j].Cells[3].Text = Convert.ToString(dTable.Rows[i]["PatCode"]);
grvSchedule.Rows[j].Cells[4].Text = Convert.ToString(dTable.Rows[i]["Phone"]);
grvSchedule.Rows[j].Cells[5].Text = Convert.ToString(dTable.Rows[i]["Mobile"]);
grvSchedule.Rows[j].Cells[6].Text = Convert.ToString(dTable.Rows[i]["Status"]);
grvSchedule.Rows[j].Cells[7].Text = Convert.ToString(dTable.Rows[i]["Comments"]);
i need to add a new row at 0 position in gridview if a condition satisfies..... Condition is
if ((i == 0) && (Convert.ToDateTime(dTable.Rows[i]["Time"])
< Convert.ToDateTime(grvSchedule.Rows[j].Cells[1].Text)))
{

I have this next gridview on my page : First name, Last name, ID.
It gets populated with data, and everything works great. I now wish to add a row just under the header (or above it- but I've been told it's impossible) with three checkboxes- one for each column.
Thing is- I geuss I would have to implement it programatically and I wasn't sure how could I pull this off.

I have to add row in gridview dynamically when a button is clicked on my page
Each Row which have to be added contains a dropdownlist(ddlQues) in which questions are binded
On selecting question from ddlQuestion I have to bind another dropdownlist(ddlAnswers)with respective
answers in that row of gridview
So autopostback property of ddlQuestion is set to be true
Everytime when button is clicked a new row is inserted in gridview and same process repeats............
I had tried following javascript:
<script type="text/javascript">
function AddNewRecord()
{
var grd = document.getElementById('<%= gvResponse.ClientID %>');
alert(grd);
var tbod=grd.rows[0].parentNode;
var newRow=grd.rows[grd.rows.length - 1].cloneNode(true);
tbod.appendChild(newRow);
return false;
}
</script>
and calling this function on button
<asp:Button ID="btnResponse" runat="server" Text=" New Response" CssClass="button3" OnClientClick="return AddNewRecord();" />
Also I tried to solve it by C#
By both ways(either by javascript or by C#)New Row is added in gridview
But when I select question from ddlquestion then page is loaded and and the inserted row in gridview disappears
I am using asp.net 2.0 with C#

I currently have a gridview on my page, which has PageSize="10" AllowPaging="true" set, so we're getting back records in groups of 10, and paging is showing as 1 2 3 4 etc... the client is asking if it's possible to also add an ALL at the end of the paging, so paging would look like:
1 2 3 4 ... ALL
clicking ALL would show everything, as if the grid was set to show all from the beginning, is this possible? anyone know how? I thought maybe the <PagerSettings LastPageText="ALL" /> would help get me started, at least show the ALL at the end, but that didn't work for me. also wasn't then sure how to setup the click event to clear the grid's settings.

I'm exporting the GridView to Excel. It works fine and I receive a prompt to Save/Open/Cancel the file although I need the file to be saved automatically in the provided (passed to the Export function) location and opened in the same browser window where the Gridview was.

I'm using a GridView to output some information regarding an account, specifically account balances. Problem is, if there is no balance linked to the account, I need for the grid to simply display 0 for each column. EmptyDataText isn't sufficient as the columns still need to be listed, but just have the value 0.
After researching it seems like I will need to add a dummy row to the gridview if it is empty, but how do I do this using C# and ASP? Quick note as well, not sure if it's relevant but the grid will only ever contain one row.

I have a gridview that contains template fields with textboxes that is used to look up inventory items. The page loads using an arraylist to display a gridview control with a predetermined number of rows. There is also drop down control that allows the user to add additional rows to the gridview if needed.
Currently when a user has already entered some data if you use the drop down to add more empty rows all the original entrys are removed. I want to save the original data and then add empty rows at the end.
>>
Private Sub LoadDataGrid(ByVal numberOfRows As Integer)
Dim Counter As Integer
Dim GridList As New ArrayList
For Counter = 0 To numberOfRows
GridList.Add(New LibVB.Form2VB(Counter))
Next
gvEnterParts.DataSource = GridList
gvEnterParts.DataBind()
End Sub

I am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
