Forms Data Controls :: Hide Repeating Column Values In A Datalist In C#?
Jun 1, 2010
I am new to using ASP.NET and I am using a datalist to represent the data obtained from querying a database.However,I am facing 2 issues:
1) If the string returned after querying the database is too long,the datalist is displaying the long string as it is which is not looking good.I am using Eval to fetch the data from the database for the sake of displaying.I need to have some page breaks so that the information fetched is presentable.
2) While repeating the datalist I want to hide all the columns except for 1 column whose value are unique.Upon searching I found this link: http://www.programmingknowledge.com/DataList.aspx but the code is in VB and I am not familiar with it.I am familiar with C#.
I am inserting the front end code for my datalist.I also want to know if datalist is the best control to present the data from the database.
For example in my datalist if Eval("OptionJ").Tostring = Null I would like the function GetVisible to set visibility of the radio button to false like so:
Updates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.
Here's the code for the Item and Edit templates. The code behind is below this.
I created a datalist which contains hyperlinks that when clicked will redraw the page and update my another datalist in the same page. How do I hide this datalist after click any of its hyperlinks?
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 datalist bound to a sql source having two columns: Name and Description. The datalist contains a "Show Description" link as follows on clicking on which it calls the javascript which shows the description div.
[Code]....
The asp.net page source for itemtemplate of the datalist is as follows.The problem is that since the div id "Description" is applicable to multiple records, no matter I click on whichever "show details" link, the description of first record in the datalist is shwon and hidden since its the first div encountred by the javascript. In other words, I want a way to show/hide the description of each record in datalist indivigdually. [Code]....
I would like to hide a submit button if a DataList is empty. I don't really know the code. If you submit an answer please show me the code also. I have to do it in VB.Net. I googled and found the following code that I place in the code behind under the Page load event.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim dv As DataList dv = SqlDataSource3.[Select](DataSourceSelectArguments.Empty)
Now the issue is that that every document doesn't has document number. I want to make invisible the docuNumber column of the grid viwe if all values in the docNumber retrieved are null.for example:
docnumber tite null Document 1
null Document 2
null doucment 3
null document 4
if returned result match above where all docnumber are null then make the gridviwe docnumber column ivisible eslemake the greidviwe column visible.
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.
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)
How can I make the column of ListView Control invisible. The last column's header I have put in a label control and its item are in a html img control .
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 an application where I display the data from sql table to details view. There are many columns in SQL table, among them I combine two colums firstname and lastname to Name using templateField.
My code:
[Code]....
So, the problem is: If Name colum is empty, No data at all, I want to hide that Name column in detailsView.
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?
Now I wanted to hide, that is to make some of the columns visible false.
First how can I do that, Second should I write the code in the same page_load event or I should write the code some where else, cause when I add this line of code
