How to get HeaderRow text when sorting is enabled? (Columns are AutoGenerated and the column that I'm trying to access is set to invisible in the RowCreated Event.)
I have a Gridview with AutoGenerateColumns= true and AllowSorting=trueBelow is the code snippet I have in RowEditing. This works fine if I dont change the column order in future.Is there a way I can access the headertext and do something like this
If headertext="Start_StateID" Then dim Start_StateID As Integer = TheRowinEditMode.cells(this headercolumns index).text end if
I've searched for this problem on Google and also on this forum (and also this forum using Google) so if there is another topic dealing with this I apologize but I couldn't find it! :)
My problem is that when I try to access the HeaderRow property ASP freaks out and gives me the infamous 'Object variable or With block variable not set.' error. Here is the code in question:
Public Sub gvwResults_DataBound(sender As Object, e As EventArgs) Handles gvwResults.DataBound gvwResults.HeaderRow.Cells(7).Visible = False For Each gvr As GridViewRow In sender.Rows gvr.Cells(7).Visible = False Next End Sub
The line 'gvwResults.HeaderRow.Cells(7).Visible = False' is what raises the error. When I remove it, the code works just like expected except that the header row of the 8th column isn't invisible like I'd like it to be.
I'm pulling my hair out here, this is the very last thing that needs to be finished before this app is usable haha. :)
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 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've read a few articles on this, but I keep doing something wrong, and I'm not sure what. I took out all of my customization and just want to add a single header row to the very top of my GridView... Can someone show me how I'm screwing up? This is the code I'm trying to use...
[Code]....
I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls[0], etc, but nothing seems to work.
I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?
(have also tried using "0" for the rowIndex when creating the new GridViewRow)
I have the following piece of code which I was hoping would result in an error message being displayed if an incorrect date format was input rather than an website error page saying "The string was not recognized as a valid DateTime."
I have a GridView where one of the colums has lots of text. Too much text to display because each rows then is almost half screensize each. Is there a way to just display the first words, and then have a function, perhaps mouse over to wiew the whole text? Tooltip maybe?
I have a gridview that is being databound by an SQLdatasource and on RowDataBound i am doing a calculation and then setting
e.Row.cells(17).text = Result
However, when I go to sort it on the website it sorts it based off the previous values.Cell(17) from the datasource reads in all 1's. The numbers I change it to range from 0 to 15. So when I click sort nothing changes because it sees it as all 1's.How can i make the gridivew sort off the changed text values?
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
Using Visual Studio 2008 (but have VWD 2010 available). Desire is populate a cell from a number of database items that have been concatenated together. Exampler would be Smith, John, 2010, Going After an Ideal Solution, 500 pages. Gridview allows me to set the cell format, but for the entire cell. I would like to present this as a mixture.
i am doing a gridview which consists of 1 checkbox,1 linkbutton, 1 textbox and 1 image button. For all the cell which has the checkbox checked, i need to collect the data and update the database.
Form the gridview, i need to collect few information before i update the database. That is the cell informaion (checkbox and textbox), and also the Line information, shift (Grave/Morning) and also the date.
I am having problem in reading out the date of each cell belong to. By using the code GridView.HeaderRow.Cell(n). text , i only able to access shift information.
The Date Information is done by adding additional header row and its coding is as below:
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.
