I have a nested gridview on my page, I have to apply sorting on that grid and wants the header to be locked. Means when I scroll the grid the header should be visible all the time.I have mousehover and onclick event applied on this grid. Whenevr I try to apply some code to fix the header, it results in detaching of header and moves up the screen on every scroll.
View 1 RepliesI came across a page that showed a solution for freezing the top (header) row of a gridview and allowed it to be scrollable. Here is the article: [URL] ....
It works and I was able to freeze the top row! However, I have a nested gridview ("gridview2") within that gridview ("gridview1") and I need to freeze it's header row...but I am encountering the following compilation error: "The name 'gridview2' does not exist in the current context"
I have tried many approaches to solve this, including calling the javascript function on the button event in which gridview2 is displayed, however I receive the compile error every time.
Here is the code that is causing the error:
<script type="text/javascript">
function gridlock() {
var GridId = "<%#gridview2.ClientID %>";
Looking for code to collapse/expand all of the rows of the NestedGridView at the same time ?
Something like 2 linkbuttons "Expand All" / "Collapse All" ...
I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries

Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

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

In Nested Grid, we get a '+' sign.  The problem is that '+' sign appears all times, even if there are no child records for that row. 1. Can we enable/disable OR Hide/Unhide '+' sign. depending on if child rows exits.2. OR alteast we can put some bgcolor indicating to user that this record do have child rows. Without any indicator user may feel quite annoying to click on '+' sign and nothing happens.
View 1 RepliesHow to pass gridview particular column values to another page's table header...
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 have a nested gridview which has been working fine. Now I need to turn the inner gridview off based on some condition: a IF block is added to the existing RowDataBound event of the outer gridview. Now I'm getting "the Object reference not set to an instance of an object" error. What should be the proper way to go about this? The code:
[code]....
In addition, is there a way to "switch" columns of the inner gridview? For example, column 1 is "City", column 2 is "Price". If user selects to sort by "Price", I woud like column 1 be "Price" and column 2 be "City". Is this has to be done programmatically or if there's other way?
I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:

Using vb.net/asp.net 2005
I have a nested gridview (gridview within gridview) that I need to render beneath the outer gridview.
I keep finding examples online of showing a nested gridview in the last column of the outer gridview but I need to show my nested gridview instead under the outer gridview.
I was certain that I had done this before by putting a row (<TR>) inside the TemplateField so that the nested gridview would display under the outer gridview. I am getting the data ok for the nested gridview, that is not a problem. The only issue I am having is making the inner gridview display under the outer gridview.
btw, the error is below:
<ERROR>
Type 'System.Web.UI.WebControls.TemplateField' does not have a public property named 'tr'.
</ERROR>
I have a nested gridview containing gridviews: gvMaster(Parent) and gvAlternate(Child)
If I select a row in gvAlternate is there a way for me to find out what gvMaster row it is under? I want to highlight the selected gvAlternate row and the gvMaster row that it is under.
[code]....
I can get a certain set of rows of gvAlternate only by referencing which gvAlternate control set I want to access: this is based on the gvMaster.Rows and then using the FindControl and id name:
GridView
gv = (GridView)this.gvMaster.Rows[aRowNumber].FindControl("gvAlternate");
Therefore, it is true that a set of rows in a nested gridview is tied to a specific row in its master gridview, the question is does the child gridview know which set it's connected to or does it's master know if a childset has been selected?
I have a parent gridview5 with child gridview 6, today i deployed it to our dev server and on that server we have alot more records, so for the nested gridviews i need to enable paging on the parent gridview5. Doing so works fine, until i make a selection within the child gridview6, once any selection is made, and i try to page the page throws an error, i have the following bound to the parent gridview5.
