Forms Data Controls :: Setting GridView Header Text When Page Changes?
Feb 6, 2010
I have a GridView (inside an update panel) that has header text that changes based on some user profile information. I set the header text in the Page_Load function of the page - that works fine. The problem is that when I change to the page number of the GridView, the header text is not redrawn. I am handling the OnPageChanging event to try to update the header text but nothing is happening. I've attached the relevant code.
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 want to fill a gridview with data from a database table..But, I have to avoid the column names from the database..I had already specified header text for the gridview.. i had already selected two column names 'name' and 'number' from a database table, then I had created two columns for the gridview( with header text's name and number)..Now i want to select the all the data from columns 'name' and 'number'..and then fill the respective columns.
I am wondering what is the best way to do this. Here is my observation:
1. If a GridView is assigned a datasource at design time, the header row's text can be retrieved with ((DataControlField)GridView.Columns[index]).HeaderText.
2. If a GridView is assigned a datasource at run time by code-behind, the header row's text can be retrieved with GridView.HeaderRow.Cells[index].Text.
Is there a way to do it without trying one, if not working, then the other of the aforementioned methods.
I have my data table generated dynamically binded to grid view. (Autogeneratecolumns true)
in my UI its displaying the column headers.
am not able to access it by grdname.HeaderRow.Cells[0].Text
am not able to get the names from the columns also.
since am binding the columns dynamically i am not able to get access to all the columns
and am able to get only 2 columns which i have mentioned in my aspx which are the command buttons edit and delete.
am trying to access all these in Gridview_RowCommand event. need to get the value in the (dynamic) column named Id for the row on which the edit or delete button is clicked. since it doesnt have a header am unable to access it bcoz i dont know the index of the cell too..
I have a merged column of firstname and lastname by "Select firstname + lastname from table" but when it appears in the gridview the header text of the column is "Expr1000". How can I change the header text of that merged column?, and I want to change its text into "NAME".
I want if the header of a particular column contains a word "S", the header and row turns red. I used following code to make header red and it works fine. How to make it such that the rows also turn red if condition is met ? I cannot hardcode in columns since the Gridview is autogenerate colums as data structure keeps changing.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs)Dim HeaderRow As GridViewRow = GridView1.HeaderRowFor Each c As TableCell In HeaderRow.CellsIf c.Text.EndsWith("S") Then c.BackColor = Drawing.Color.OrangeRed End If Next End Sub
I have the grid view with boundfield with four columns. I created the text box when gridview row created event. I need to filter the data the gridview using the textbox and need to know the how to generate event for textbox.
The problem is this: I am writing a system to show helptexts on certain labels. So in the PageLoad I recursively iterate all controls and save those with a certain tag. So far so good.
On the PreRenderComplete I iterate the controls and set their text property. The strange this is that the labels in ItemTemplate don't get the new text. The PreRenderComplete fires after the DataBound event of the gridview, the label gets found perfectly, in the end it has the new text, but in the page it's still the old text.
I hope I don't need the Row_Databinding event of the gridview, since I want to put all the functionality in an extender class with as little custom work as possible.
Let's say I have unsorted 2 types of data.2 list box contains. 1,2,15,6,4 and apple, banana, carrot, dove, eggplant. . How can I sort it then make it as my HeaderText for GridView Column after a button is clicked?.
In my Webapplication i am trying to export GridView data into PDF format and the application is working fine.But in the resulted PDF file i'm not getting GridView Headers.

how can I access their header text programmatically ( display it(either using response.write or any label)
I am trying to create to a college time table, I am not sure how to display calendar date and day in GridView header. Also, how to display editable time in the time table .
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 gridview with div tag, i have put div tag becouse when user scroll in grid i dont want move grid header section. Its remaining ther and only move data section. Its working fine.

Scenario: 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,
