View 14 RepliesScenario:
I have a Gridview where I want to handle the Sorting in a custom control that I've added to the header.
I've added this control to my GridView's Header via OnRowCreate event handling. I want the Sort Expressions to persist session to session (via Webparts Personalization)
Here is what I have for adding the custom header control to the GridView Header
[Code]....
This works out well for adding the control, but I can't get anything to persist because these controls are creating initially via postback (per the event) and re-created on all subsequent postbacks. I can't add an If(!IsPostback) because the controls are initially created on the gridview's postback (well at least thats how it's acting when I put it in there) If I were to add this control via the ASP page, not via the Codebehind, I would be able to persist the control. If I try to treat it as though everything is setup correctly, and assign my custom control's controls to [Personalizable], I get a runtime error telling me that I can only have webpartzones in or before Page_init (I'm guessing this is due to when/where the
gridview hits the OnRowCreate event). If there is some fundimental logic I'm missing, or best practices that I'm moving away from,
is there anyway i can add in the gridview in header column name a button instead of label ?
column name 1 column name 2 column name 3 button
i am using checkbox column in item template for the button ,i wish after selecting checkbox for some row to click on the button on the header !!
I am using the following code to change the header based on the session variable

ASP.NET 3.5,I'm upgrading a page that currently uses classic asp and xslt to display about 2000 readonly tabular records. Please leave aside the issue of whether this is a good idea or not.My asp.net replacement page uses a gridview to do the same thing.The scrolling in IE8 using this old code is very smooth and even. The scrolling using the asp.net page is horribly jerky. I can't figure out why - there doesn't appear to be much client side code running.Any clues welcome as this is a high traffic page that I want to look as good as possible.The same page also can't handle a row highlighter - same reason slow and jerky.
View 2 RepliesI put a GridView control in a Panel control so that the GridView's rows can be scrolled vertically. With selection of row enabled for a Button field, I am able to select any row with the selected row background color highlighted. Problem is when you scroll down to a row that is way pass the Panel height and select the row, after postback the GridView will render to show the top rows which are visible within the Panel height. So the selected row in it's background color cannot be seen.

i got a problem trying to keep header visible when scrolling in a report the thing is that i'm doing exactly what says in this page [URL] the thing is that i can't get it to work viewing the option, i realize that the option that i have to check according to the page says "Header should remain visible while scrolling" the one i got in the visual studio 2008 is "Keep Headers Visible When Scrolling"

View 1 Replies i have a gridview bound to sql datasource with template fields binding the columns. I have set the Header Style to a css class. I have 3 columns not bound to data as Add, Edit and Delete. When I set the text color to white for the header only the non bound columns go white. The bound columns are BLUE like hyperlink. Any one know a way round this. (If I set the style in the gridview the all columns are white. Want to set in external css file).

I am just trying to view gridview that is inside other gridview but it is not visible although its visible = trure.
Here is the code:
[Code]....
I have used a GirdView to display data from database,  data would be huge around 670 rows. And also I want to display all data together on single page.
Therefore I want to use virtual page scrolling. Means on Page load only 20 rows would be displayed, then when page would be scrolled next 20 rows would be displayed.....
I have a customized gridvew i.e. grvResult. There is a textbox and a InsertButton in the footer.
If there is a data populated into gridview it is showing GridView footer and inserting data but if there is no data in gridview then its footer also not visible.
I have tried in two ways to make footer visible but it is showing following error:
Object reference not set to an instance of an object.
Tried ways:

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 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.

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 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
I have GridViews in mostly all web-pages. If data rows are too much then by scrolling down the grid, header misses.
How to Freeze GridView Header like we do in MS Excel?
<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)...............................
