Forms Data Controls :: How To Hide Gridview Column Programmatically
Mar 24, 2010
I've programatically created a DataView item by adding columns and rows to a table in the class file. Then I add that to my webform using a GridView. I'd like to hide some of the columns so that the end user doesn't see them but still be able to access their values.
How do I do this programatically? The table.Columns.Count returns the actually number of columns. Somehow when it converts into a DataView, it is only returning 1 column.
As per my requirement, I am getting CompID, Company Name and URL from SQL database. I want to display just CompName and URL in gridvew. So, I need to hide the CompID in gridview. One way I can do BoundField field Visible to false but I need to retrive that compID id when user selected any of the row. if I set visible to false user wont see any compID in gridvew but I want access the selected compID also using SelectedRow.Cells[1].Text..
I have a GridView which pulls info from a SQL DB. It works fine. I use a CMS to upload the data which includes thenumber referred to below.
The last (rightmost) column in the GridView is a number.
I'd like to know how to know how to:
1) Make a further column visible (to the right of the number) which contains a Button BUT only when the user is logged in.
2) Make that Button call a function (the workings of the function are irrelevant here) and pass to that function the number in the previous column.
I know I could use a LoginView with two GridViews, one for logged in (showing the Button) and one for anonymous (without the Button), but then I'd have to put the Button in the database... I think.
A better idea would be to add the Button column programmatically.
how this can be done and how the Button in each row, when clicked, can pass whatever number is to its left as a parameter?
I have a gridview that has certain values in it that I would like to change based on a condition. For example, if a value in the column is 'x', I would like to make that Value Bold and have text that says 'Not applicable'
How can I do this? How can I programtically chnage values in a gridview?
Now in server side i am trying to hide this column but failed !!
protected void gv_RowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.Header || e.Row.RowType == DataControlRowType.DataRow) gv.Columns[2].HeaderStyle.CssClass = "hiddenClass"; // here i am setting display:None using css class }
I am facing a problem with Gridview control. I have created a Gridview1 which is having 3 button column that has been added at design time and some column can be added through the Datatable at runtime. At Design time GridView1 has 3 button column
At Runtime I do GridView1.Datasource=dt; //Now my gridview is having 7 columns i.e. 4 more columns added through datatable.
I can easily display that GridView1 on webpage but I dont want to show some column that I added through Datatable to the user.
When I try to hide that column, I get error like Index out of bound exception but when I hide button column I can able to do that easily.
I have a gridview, which contains a template field with a button. On this button, I want to show and hide another column with this one button. I don't want to use Java Script because my site already uses a lot of this and AJAX. So, can someone show an example of some code behind, which is what I want to do on how to show and hide another column on a gridview?

So on Page2 the buttons should not be seen...
I am trying to hide the first column of my gridview, a template/command column.
I want to export my gridview to Excel and the teplated contol shows up in the Excel file as a column.
This is what I tried in code :
Me.GridView1.Rows.Item(0).Visible = False - This doesn't work ! Me.GridView1.AllowPaging = False Me.GridView1.AllowSorting = False Me.GridView1.EditIndex = -1 Me.DataBind() Response.Clear() Response.ContentType = "application/vnd.xls" Response.AddHeader("content-disposition", "attachment;filename=SearchedItems.xls") Response.Charset = " " Dim swriter As New StringWriter() Dim hwriter As New HtmlTextWriter(swriter)
