How to get HeaderRow text when sorting is enabled? (Columns are AutoGenerated and the column that I'm trying to access is set to invisible in the RowCreated Event.)
View 3 RepliesI have the following function that translates the header row in a gridview:

When I added sorting to the gridview cell.Text does not work anymore. How can I access the header text in the cell?
I have a Gridview with AutoGenerateColumns= true and AllowSorting=trueBelow is the code snippet I have in RowEditing. This works fine if I dont change the column order in future.Is there a way I can access the headertext and do something like this
If headertext="Start_StateID" Then
dim Start_StateID As Integer = TheRowinEditMode.cells(this headercolumns index).text
end if
[Code]....
In my application I am sorting the gridview and also have Edit in that gridview, sorting works fine but when i click Edit, it puts the gridview in the original sorted order. when i click Edit - it lets me edit the row but it changes the order and show me the original record on that row in the edit mode.
below is my code:
protected void GridDispatchshow_RowEditing(object sender, GridViewEditEventArgs e) {
GridDispatchshow.EditIndex = e.NewEditIndex;
Label lblpblm = (Label)GridDispatchshow.Rows[e.NewEditIndex].Cells[10].FindControl("lblproblemfaced");
// GridDispatchshow.DataBind();
fillgridview();
[Code] ....
I've searched for this problem on Google and also on this forum (and also this forum using Google) so if there is another topic dealing with this I apologize but I couldn't find it! :)
My problem is that when I try to access the HeaderRow property ASP freaks out and gives me the infamous 'Object variable or With block variable not set.'
error. Here is the code in question:
Public Sub gvwResults_DataBound(sender As Object, e As EventArgs) Handles gvwResults.DataBound
gvwResults.HeaderRow.Cells(7).Visible = False
For Each gvr As GridViewRow In sender.Rows
gvr.Cells(7).Visible = False
Next
End Sub
The line 'gvwResults.HeaderRow.Cells(7).Visible = False' is what raises the error. When I remove it, the code works just like expected except that the header row of the 8th column isn't invisible like I'd like it to be.
I'm pulling my hair out here, this is the very last thing that needs to be finished before this app is usable haha. :)
I am trying to change the text in the header column when the GridView is sorted by checking the SortedDirection of the GridView.
problem: The text in the header column gets changed after i have clicked three times to sort the GridView.
i don't understand my problem. it seems really simple to get it work...this is what i done on each databound

I've read a few articles on this, but I keep doing something wrong, and I'm not sure what. I took out all of my customization and just want to add a single header row to the very top of my GridView... Can someone show me how I'm screwing up? This is the code I'm trying to use...
[Code]....
I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls[0], etc, but nothing seems to work.
I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?
(have also tried using "0" for the rowIndex when creating the new GridViewRow)
Is there any good solution for ajax enabled Grid with pageing and sorting which only brings the required data from database? I mean it should only bring the data from the database which is to be displayed on the particular page number of the grid.
I looked at this. It looks good. But I just thought if anyone has created something better using Google's or Yahoo's javascript library or using any good features of asp.net 3.5.
Moderators Note: THIS ISSUE IS BIG FOR ME AND EVEN IF POSSIBLE, GET THE REPLY FROM THE DESIGNER OF GRIDVIEW. I have been looking for him for long. I am really fed up with reviewing a good lot of web pages on how we can possibly customize the gridview to enable sorting and paging. So many sites have listed out a lot of information and so many guidances. But the problem is that one works out fine and the other is a burden. I really feel bad about being given the job of customizing this kind of a gridview which has no user friendly approach to it. Also, this control is rendered without the pager links inside the <tfoot> tag. I have tried the Pear Pager in php. It is that good and easy to use and compared to that, the gridview in asp.net is the worst ever control i have ever tried so far.
1. i can use the images to indicate the sorting direction
2. I can have the custom pager like
[code]
<<Previous 1 2 3 .. 7 Next >>.
[/code]
When i click the next when i am viewing the page at 3 , the pager links should change as
[code]
<<Previous 2 3 4 .. 7 Next >>
[/code]
Kindly look into this type of requirement and firstly tell me whether this is possible with the gridview control. I would like this request even to be escalated to the designers of the gridview control also, so that Microsoft comes out with a reply THAT WORKS and not the kind of stuff like surfing through a lot of links and pages and finally wasting a lot of days precious time and still breaking the head with this useless control. I have spent a lot of time in searching for a perfect way. Not writing a code that is non-standard. I am really serious b'cos I have spent weeks in customizing this control. If I dont get a solid reply atleast now, I am going to generate all the output by HTML content by custom coding.
i have gridview in my page
i don't want show header in my gridview i search all property of this control but i didn't find anything
So far, I've seen (and I'm using the following) scripts to show/hide a div or other controls depending on another control in ASP.NET
$('[id$=myRadio_0]').click(function() { $('[id$=myDiv]').show(); });
$('[id$=myRadio_1]').click(function() { $('[id$=myDiv]').hide(); });
and of course, my div in html like
<div id="myDiv" runat="server" visible="false">
and that works fine when the user selects either option of the radiobuttonlist. However, when I assign that radiobuttonlist a value of 1 or yes on my Page_Load on code behind, that isn't (and probably can't be) caught by jQuery, and my div remains invisible even though the control has a value of Yes/1. So, do I need to set the visibility of that div from code behind, or is there a way in jQuery to force a scan of these dependencies after i've set the values for the main controls in code behind?
I have a multiline text box on a form. I dropped in the js file for openWYSIWYG and attached it to the textbox. When I submit the form, the text box has no value. I'm having problems finding documentation on this library.
The HTML is here:
<table>
<tr><td>Comment</td>
<td><asp:TextBox ID="txtComment"
Height="150px"
TextMode="MultiLine"
runat="server" />
</td>
</tr>
<tr><td colspan="2"><asp:Button ID="btnSubmit"
runat="server"
OnClick="btnSumbit_Click"
Text="Submit" />
</table>
<script type="text/javascript" language="javascript">
WYSIWYG.attach('<%= txtComment.ClientID %>', full);
</script>
The codebehind for the method is:
public void btnSumbit_Click(object sender, EventArgs e)
{
//txtComment.Text is "" The text is not available
}
I need to remove certian rows from the Gridview so that certian users can't see certian rows. I have a row databoud event that checks for certian fields in the row and disables the entire row based on the value of those fields. However, it dosen't work well because if my gridview has 20 or 30 rows I have paging so if it disables all but 2 rows the user has to click in the pages of the entire gridview until they reach that row.

I'm trying to sort GridView but I have problem with converting DataSource to DataTable. Object of DataTable is empty. I don't know how to convert it.Do you have any ideas? Here is my code:
private void SortGridView(string sortExpression, string direction)
{
DataTable dt = GridViewDzialania.DataSource as DataTable;
DataView dv = new DataView(dt);
dv.Sort = sortExpression + direction;
GridViewDzialania.DataSource = dv;
GridViewDzialania.DataBind();
}
When i try sorting in the database, it sorts the numbers:
1
102
2
304
305
4
4 Rev 01
etc....
but i want to have it sorted like:
1
2
4
4 Rev 01
102
304
305
What must i do to make it so? I just use a normal datagrid with sorting capabilities enabeld. Data type is varchar.
