I my site there is grid view and the option auto generated column is true of gird view
At run time I am hiding and showing columns as user has set it.
I want to count visible columns at runtime but I am facing a problem to count
When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

I have a gridview that is bound to a SQL datasource and is filtered via FilterExpression,
the FilterExpressoin is using Contro Parameters in a for of textboxes.
I want a certain button to become visible (btnInsert.Visible=true) when the filterExpression returns no results.
what event should I use? what is the code for that?
I've created a gridview having an Id column whose visible property is set to false, because I don't want users to see that column. Now when user clicks on the edit button in a particular row I want to fetch the id of the cell in the Id column of that particular row. So, for that purpose I used -
void GridView_RowEditing(object sender, GridViewEditEventArgs e)
{
string Id = GridView.Rows[e.NewEditIndex].Cells[0].Text;
}
In the above code, Cells 0th index is the column index whose visible property is kept false. Now the problem I face here is that if the columns visible property is true then I can easily fetch the contents of that particular cell with the above code. But, in invisible mode I get only "" value i.e. I don't get the text or the content of that cell. Why does it happen? I don't face this problem with DataGrid Control used with 1.0 and 1.1 version. And how to resolve it or in this case is there another way of fetching the content of the invisible cell?
I am Just Filling My GridView using OleDb Control from Excel Sheet. and When I want to Save that I must have to Go through the Number of Columns to read at the End of Record.
I am Using
Dim Rows As Integer = GridView1.Rows.Count
Dim column As Integer= GridView1.Columns.Count
msgbox(Column) '--> Here I am Getting Value Zero
for i=0 to Rows-1
Fori=0 to Column-1
'Work to Perform

Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
Label1.Text = GridView1.Rows.Count.ToString()
Dim ONYO As Integer = 0
Dim DONE As Integer = 0
For i As Integer = 0 To GridView1.Rows.Count - 1
If GridView1.Rows(i).Cells(0).Text = "ON YO" Then

GridView1.Rows.Count.ToString());...............
I habe a arraylist that can pass in the result of a quiz and once the user finishes this quiz, the result will be displayed in a gridbiew which is binded into a sqldatasource. In this gridbiew, there is this column which will highlight the the result of this qn which displays correct and incorrect. what i want to do now is, i want to count the number of correct answers. I want to count all the correct answers and bind it to a label in the same page.
View 2 RepliesI'm binding a gridview from a webservice with 30 columns and 10 rows, I need to print the same in a PORTRAIT, for that i decided to display columns as rows and
rows as columns like below:
EMP1 1 2 3 4
EMP2 1 2 3 4
I have a master/detail page using a gridview as the master, and a detailsview as the details. The gridview is set to select a record, and the detailsview picks up the ID and you can either edit that record, or add a new one.The detailsview is set up with various template fields, and if everything on the page is visible, it works OK.However, I wanted to hide the Gridview when the user in working with the detailsview. But if I do that, the detailsview doesn't update the record.
View 2 Repliesi have a gridview inside a div that has scrollbars. see bellow
[Code]....
is there a way to keep the gridview header always visible while scrolling down.
like in MS Excel.
I am able to get the values of GridView cells when the columns are not visible.
For Example:
<asp:BoundField DataField="TemplateKey" Visible="false"/>
foreach (GridViewRow gvrow in GridView1.Rows)
{
gvrow.Cells[0].Text.ToString()
}
But if I make the BiundFiled Visible="true" then I get the value in the code behind.
I do not want to show this value to the user and also want to get the value in the code behind. How can I do that?
Whenever you turn off the visibility of a column in Gridview, on Edit, the value becomes null because its never bound. The only way I know of stopping this behavoir is to put it in the DataKeyName list. Is there any other way to prevent this? I have quite a few columns that will not be displayed in this "release" but I want there for future extensibility. Also, in some cases these values will be used for calculations but the user should not see them. Is there no toggle property for "non-visible" items to remain "unchanged" or something of the sort?

I have an Outer gridview (called grdvOUTERGRIDVIEW) and an Inner Gridview (called grdvOUTERGRIDVIEW) and I am able to see and use the outer gridview in my codep-behind vb page however when I try to handle an event for the Inner gridview then I get the warning: "handles clause requires a withevents variable defined in the containing type or one of its base types".
After creating the inner gridview I closed the page out and re-opened it however still getting that error and not able to create the grdvINNERGRIDVIEW.RowDataBound event function like I am trying to do.
the gridviews are below:

I am having a strange problem. I put on a Gridview on my aspx page. I also data bound it to a table from my SQL server.
Other than that I wanted to put in the Edit, Update and Cancel functionality so I also put in this from the Gridview Smart Tag.
Following is the gridview aspx code can anyone tell me what I am missing here?

I want to count all checked checkboxes in gridview. How can I possiblty do that? I've tried several ways but didnt work. This is my code for checkboxes.
[Code]....
<asp:ButtonField Text="Void" ButtonType="Link" CommandName="Void" />
' RowCommand
Dim f_iIndex As Integer = Convert.ToInt32(e.CommandArgument)
Dim f_oSelectedRow As GridViewRow = grdMeterCorrection.Rows(f_iIndex)
Dim f_oCertIdCell As TableCell = f_oSelectedRow.Cells(11)
Dim f_sCertId As String = f_oCertIdCell.Text.Trim
If e.CommandName.ToLower = "void" Then
Dim f_bVoidRet As Boolean = VoidCert(f_sCertId)
End If
The problem is the CertId field in the GridView has visible set to false. I think this makes the value unaccessable to the RowCommand.
I have a Gridview with some template columns. Inside one of the columns, I have a ImageButton with a serverSide OnClick handler to show or hide a panel. And all the panels by default are hidden. What happens is that when I click the imageButton the first time the panel gets displayed, but if I click the same button, on the same row again, - where the panel is now visible - the panel doesn't hide itself. Here's what happens when the imageButton is clicked:
protected
void ImageButton1_Click(object sender,
ImageClickEventArgs e)
{
ImageButton imgBt = (ImageButton)sender;
Panel compRecDetails = (Panel)imgBt.NamingContainer.FindControl("CompanyRecDetailsPanel");
if (compRecDetails.Visible ==
false)
compRecDetails = true;
else
if (compRecDetails.Visible ==
true)...............................
The example .aspx page below includes a grid containing two checkboxes. The first is hidden because its ItemTemplate.Visible is set to false. What is the cleanest way to avoid OnCheckChanged when the parent cell is not Visible?Paste sample below into new .aspx and run. Uncheck 'Visible' Click 'Test'Expected Results (since only the 'Visible' checkbox was changed):
Visible
.Checked=False
.Visible=True

I'll start off with a snapshot of the application i'm working on.
Basically, what's going on is i'm using a bunch of sqldatasources to track truck loads (shown) based off a date/ date range. As there are generally multiple loads that all have the same information, so the information is grabbed with a SELECT DISTINCT so that you're only seeing one entry per multitude of loads. From there, customers can select the load type they want to work with and it goes into more detail, such as who trucked the different loads in, where it came from, where it's going to, references, that kinda stuff.
My question is, would it be feasible to show how many loads there are in total per distinct select? For instance, the top entry actually has 14 loads that are similar to that entry. How would I go about showing it has that total of 14 loads that could be shown?
I'm trying to use this code for counting and presenting total No. of rows returned for a grid view with AllowPaging="true" & PageSize="15".
getting the "object reference not set...." error for the "DataSet tbl" line:
