I have a grid view which is dynamically generated via C# using a DataSet. I'm passing a row ID field (from the database) to the grid view, as this is required when a user clicks to edit a records. However I don't want the user to be able to view the column.I have tried the following but it doesn't seem to work? hide the column or a better way of attaching the information to the grid view row so it can be used at a later stage. c#
DataColumn ColImplantCustomerDetailsID = new DataColumn();
ColImplantCustomerDetailsID.ColumnName = "Implant ID";
ColImplantCustomerDetailsID.DataType = typeof(int);
ColImplantCustomerDetailsID.Visable = false; <-- visable doens't work here.

I have an ASP.NET GridView control in a Web Form. For the sake of simplicity, I will say that this GridView is defined as follows:
[code]...
When each of these rows is bound (a.k.a. during the "myGridView_RowBound" event), I want to get the ID, Name, and Age values. My problem is, I cannot figure out how to get the "ID" value. The reason why is because it is in an invisible field.
How do I make a column invisible in a gridview? I tried to use this:
dataGridView.Columns(0).Visible = False
But its getting an error "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index". How can I do this?
How do I pass a GridView column value to the code behind with out making it visible? In the following code, I would like to capture the ContactID with out making it visible in the GridView.
I would like to capture ContactID as follows. I can not do so with out making it visible = true in the GridView.
if (e.CommandName.Equals("Remove")) { int index = Convert.ToInt32(e.CommandArgument); int ContactID = Convert.ToInt32(GridView1.Rows[index].Cells[0].Text.Trim()); }
Dim Application = From AL In db.AnnualLeave _ Where AL.Approval <> True _ Select LeaveID, EmpID, Name GridView3.DataSource = Application GridView3.DataBind()
after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.
I m getting 9 columns from database in a dataset but I want to diplay only 4 columns in datagrid. Remaining 5 columns values, I want to display in the textboxes below datagird.
I tried it making column invisible. If I make it invisible, I m not getting any value for that column to display in the textbox.
I bound the gridview having some fields(ID, StudName, City) Â and Display Button. When I click on the Disply button I approve the student and updation will happen.Â
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... Â next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :Â
<%# Container.DataItemIndex+1 %>
and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?Â
regarding gridview Template column.in my template column i have a textbox and i need to invisible to user. but when i set visible property "false" then textbox value is not render.
in a posyback button click event i get the status(condition ) from database by executin query as said earlier currently i have this controls visible true/ false on server side code in posyback button click event after getting the condition but as suggested by u as it takes longer time on server side to makes controls visible true false to do it on client side so in posyback button click event i assigned a hidden control with the condition value now i want to pass this value to client side script so that i can toggel the visiblity depending on hidden control value from posyback button click event i am activating the setype function in client side which has the code as mentioned...wht i need is pass the hidden value to clinet side & make & position the controls on client side.
I have a database table column consisting of text URLs [URL] In my LINQ-to-SQL-driven gridview, I want to make this a clickable link programmatically, with differing link text (e.g. "Link text"). I'm getting close but am missing some key concept. Here's the core of the .vb codebehind:
Dim dctx As New ResourceMod.ResourceModDALDataContext Dim eleResObj = From eleRes In dctx.Resources Where eleRes.Type = "url" Select siteurl = eleRes.Website GridView1.DataSource = eleResObj GridView1.DataBind()
This displays the raw URL in the gridview (i.e. non-clickable). I've experimented with adding an explicit hyperlink column a la [URL](setting AutoGenerateColumns false etc.), but haven't yet figured out how to assign the asp:hyperlink Text and NavigateUrl fields with the anonymous-type object eleResObj. Using a field construct such as Text='<%# Eval("siteurl") %>' isn't working, presumably a scope issue. Is a LinqDataSource needed in this case, and if so, how would that affect the original LINQ query?
I am trying to make columns of a gridview invisible if they contain a space. The page contains a combo box which users can change. This causes a change in the data in the gridview. I use the following code:
[Code]....
[Code]....
What is working: On the initial page load, the correct columns are deleted. However, if the user changes the combo box, and the gridview has different data loaded into it, it cannot make visible what was previously invisible. I added the ...visible = true line to get round this, but when I load the page, it seems to get locked into a loop forever, and the page never loads - this is why the line is commented out.
This should be soooo simple, but it's making my brain smoke. I've tried writing the results on whether there is a space in the cell to an array, and then using that to make the columns invisible. I've tried doing this in different events, but it always has the same problem.
I suspect that if I can find out how to reference the contents of the gridview from outside its events, it may be easier.
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 have some tables in my asp.net mvc application for layout purposes. Even though I usually use divs for most things, in some cases tables make most sense because they already have exactly the layout I'm after in these cases.
The only problem is, as far as I know the borders are supposed to be invisible unless you specify a width and style for the borders. But they aren't... They are rather vague, yes, but there are still light blue borders around each cell. What is that and how do I get rid of them? (Funny thing is I don't remember having seen this before when I used tables, which was a while ago).
I also tried specifically setting the border to 0px on both table and td, but that didn't work either...
I have a GridView which is linked to the database via SqlDataSource.
What I would like to do is to make each row of a designated column clickable. Once the user has clicked on a row, the application should postback to another page to allow the user to read all the details of that row.
The effect should be as we can see in this post: if you go to "mypost", you have a list of posts and then when you click on one of them you are able to see the details of that.
I read lots of posts that are using, however, other methods such as datalist + dataset controls etc.
I have a gridview control inside an updatepanel. When I run the app and look at the source code generated, there is no source code about gridview. So, I can't aproach to the elements inside the gridview.
My question is, where is rendered code of gridview and how can I approach controls inside it?
I have a query expression which I am binding to a GridView in Page_Load. The data I want to capture in the SelectedIndexChaned event is in a BoundField defined thus:
Can we get a reference to a boundfield column value which has been made invisible ina dynamically created and databound gridview. I am able to get a reference to a button field which is added to the grid dynamically like this:LinkButton _singleClickButton = (LinkButton)e.Row.Cells[5].Controls[0]; (the button field is the 5th column in the gridview and it is made invisible through visibility property)
let me explain completly. I designed an gridview, header template i added one textbox and button if the user enter something on Txtbox and click button then based on input i show corresponding rows only, all other rowss will be hidded using Javascript like below
tblOrders.rows[CurrRow].style.display = 'none';
now im doing something on the Gridview_RowCommand event at this time the gridview got refreshed so that the hiden rows are visible, but i dont want to show the hidden(invisible) rows while rowcommand event fired.
I have a gridview that is being populated off of a query that has joins in it. It works fine. However, I want to display one record of all information but then blank out all colunmns accept 1 for the other 3 records that it is picking up. In other words, right now, all three records have duplicate info in them accept this one column. can this be done? Can I somehow blank out other columns based upon what is in the single column? This is all being done in a gridview. I realize it would do a master detail type scenario but I want all of this information to display without someone having to click on a field or anything.
I've run into this before, but I was using a formsview and just changed the field to hidden. I am trying to get the value of a cell out of a gridview to a variable and here is the code:
[Code]....
This works perfectly if column 6 is visible, but because it's an id number (which is not the primary key) I do not want it visible, but changing it to visible="false" causes this code to return null. Changing it back to visible and it works.
I'm not sure why the visiblity of a control changes the functionality of it.
I have a Gridview with some template columns. Inside one of the columns, I have a ImageButton with a serverSide OnClick handler to show or hide a panel. And all the panels by default are hidden. What happens is that when I click the imageButton the first time the panel gets displayed, but if I click the same button, on the same row again, - where the panel is now visible - the panel doesn't hide itself. Here's what happens when the imageButton is clicked:
I want to display gridview column heading when mouse over to the particular column in the gridview.I am working in VisualStudio 2005 with MS.Net2.0 framework.I don't want to use ajax.
Query 1 - Grid View: - I have an excel sheet which I import into gridview at runtime. For excel sheet import, I have a fileupload dialog box and an asp.net button control which when clicked imports the sheet contents into a gridview. The problem is I have my fileupload box and button control in a page called Default.aspx and I need the gridview get displayed maximized in a new page called Default2.aspx.
Also, I need to specify the row number of the field titles from the excel sheet dynamically at runtime so that the gridview appends any new field/column from that row on. The excel sheets I use contain complex formatting. Is there anyway to display the excelsheet contents as they have been defined and formatted?
Query 2 - Sessions: - I add nodes to my treeview dynamically at runtime. Since HTTP is a stateless protocol, the changes which I do remain only for that session. How do I append the changes I do to the treeview simultaneously in the code?
- I have appended 2 extra columns into the excel sheet generated gridview which take input through dropdownlistbox control at runtime. How do I update and retain those changes in the gridview?
