I recieved a page to make some changes, and one of them is to change the hearders of a DataGrid. I'll have to merge some collumns.
I have searched a lot of solutions for cases similar to mine, but I couldn't make any of them work.
The code is above:

At the outset i would like to welcome all as this is my first post on this forum :)probably i've got a simple problem for most of you, namly:I want to dynamically replace ImageUrl into DadaGrid cell. I've already prepare a right type of field (Image Field) and this is my code:

View 7 RepliesI want to PIN the header part of my DataGrid or GridView? How is it possible? Ex: Suppose we have 100 rows in data grid, and 1 row with header. If you scroll data grid, header row shouldn't scroll. It should be fixed or PINNED. Only rows with data should scroll. Is there any in built function in data grid to achieve this functionality or any other methods to do this?
View 1 RepliesI have searched numerous articles for how to accomplish freezing the Header Row of a DataGrid or GridView component being to simply hide the header and then build table cells just above the component to define the columns. But the one that I'd like to get to work is by the use of CSS code. Problem is that this code seems to work for everyone else but it isn't working for me. Here's my Stylesheet code:
[Code]....
When I run my page I get all the styles applied but the header scrolls with all the other rows in the grid.
why this code is probably not working? I am using .NET Framework 3.5 and developing in VSS 2008 which may be why this doesn't work?
I have successfully downloaded sample code from Code Project which works using other techniques as well, but the code was written in .NET 1.1 Framework and VB.NET.
I have an asp.net gridview which represents some kind of reservation calendar. Each row represents a workplace and each column a day. The header value (date) is set by a method since the start of the time period shown by the gridview can be selected by the user. Since the date column can start at every day of the week I wanted to mark the weekend day columns with a special background. How to set this? (See .aspx code snippet below which is currently used for each column ().
Remark: ItemStyle-BackColor= '<%# %>' (dynamic) annotation isn't allowed in the <TemplateField> Tag and the actual date must be evaluated somehow from the header or another control.

I have a datagrid and vertical-horizontal scrollbars in it. now when datagrid will have more records , scoll bars will be provided. now when i scroll vertically , my header line of the datagrid is also scrolling so i wanna freeze it. i have used javascript to freeze it , its working in IE properly but there is problem with other browser.
i used this :[URL] but its not working in other browser.
I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.
How can I create below type of gridview with merge merged header columns? If anybody have example share with me.
View 1 RepliesI have a members section of a website where when they first register to become a member, they pick their top 5 sports personalities/stars. Then when they log in to the members area, I want to display members news which should show:
- at the top all new stories that have been their sportstar has been referenced to
- then all other news
(In the CMS, admins can edit a news story and they have 5 dropdowns of all the sportstars so they can for example have for a news story: Sportstar1=Tiger Woods, Sportstar2=David Beckham etc) So as a member, if I have selected David Beckham as one of my top 5s, then all news tagged with him via the CMS are displayed.
There may be a better way to approach it, but basically I am creating one DataSet, then firing off 5 SQL queries, each SQL query is like this:

Then in my Page Load I do this:

The problem is that my repeater is inl showing news for myStar1 i.e. it is nly showing the first table which will be called "News1".
So is there any easier way of doing this? Am I overcomplicating things?

I have two SQL queries that are stored procedures that have 2 variables that my web form will be supplying through text boxes. The two queries will produce two different results. I have read a couple of different of the MSDN articles online, including this one:

that say that the tables must be similar to be able to merge them into a single datagridview. I know that datagridviews only like one table at a time, but I was curious if anyone had found a way to merge two dissimilar tables to one datagridview or not.
how to display a header of gridvew as a 3D view color Header?
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 have a problem with ListView control,when i bind data to it, it shows the heder of it also.
i don't want to show me the hedear, what should i do?

I have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
