Forms Data Controls :: Retrieve GridView's Header Row Text?
May 24, 2010
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 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 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 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 know there are a number of posts along this topic, but everything I find seems to not have a final solution or else I'm just not getting what the solution is. I have a simple GridView with a ButtonField and a BoundField. I'm having the same problem most of the other posts seem to have; I can retrieve the BoundField value easy enough in the RowCommand subroutine, but I can't figure out how to get the value of the ButtonField. Here is the code I'm trying to use:
[Code]....
sAddr is being set to the correct address value, but sName is set to an empty string no matter what I try. The GridView HTML all works correctly, including showing the names from my bound data table on the button text. I can use to retrieve the ButtonField text value?
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.
I am using VB and trying to get the first value of the cell of a gridview. The gridview is returning a header and 1 value.
In the code behind I have used the below, but the textbox is showing " ". It is not populating the first cell of the gridview databind.
Protected Sub GridView3_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)If (Not (e.Row.DataItem) Is Nothing) Then ' Set the capacity label text TextBoxTest.Text = e.Row.Cells(1).Text End If End Sub
I have a gridview which i bind to DataView. I need to manipulate text on cell[2] of each row. I was wondering if i could do it in the OnRowCreated event? cell[0] in asp looks like this
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.
I want to access the header text of bound fields programatically. suppose i have GridView1 with following bound fields:
<asp:BoundField Visible="false" DataField="ID" HeaderText="ID" />Â Â Â Â Â Â Â Â Â Â Â Â Â <asp:BoundField DataField="Title" HeaderText="Title" />Â Â Â Â Â Â Â Â Â Â Â Â Â <asp:BoundField Visible="false" DataField="Description" HeaderText="Description" />
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 .
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,
I want linkbutton to have header text. Scenario is like when user clicks on proposal_id, in code behide i want to retrieve id. I am able to retrieve but i want header Text to be displayed. I am not able retrieve id using ButtonField.
