VS 2008 Gridview - Hide Certain Columns And Change Column Names
Jun 15, 2012
I have a gridview that I am loading from a stored procedure. I need to be able to hide certain columns and change the column names. Since it is loading with stored procedure the columns aren't listed in the gridview->edit columns properties.
in asp.net page user able to select gridview Columns, and it will hide remaining columns and that selection done by check box with column list bellow is Image link , what exactly I am looking for [URL] it look bellow after selection of column done [URL]
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 the asp.net application where I am having the editable grid view with the edit,Delete,Add options. this grid having as usual Template fields . I want to hide some columns. I know i can do that by using columns index. but i don't want to follow it. instead I want to hide columns by Id. this is because if in my application further I need to add more columns then there is need to change the code gain and again in the core. so I am choosing this way. Bu as i found <asp:TemplateField /> does not contain Id attribute. so it is become impossible for me to hide <asp:TemplateField/> by Id.
my sp return resultset with different column names based on different parameters passed to sp and now i want to show that data in asp.net(c#) gridview so how can i achieve this
I want to hide few columns of a gridview before they gets displayed. I want to do it by create a common function which can be used by multiple controls. I am using an extension and would like to know how it can be done.
Here is my code
[Code]...
I want to create an extension to hide or show columns provided in the list as an array. 1st function is used on page. While below two functions are needs to be used for multiple applications
I've got a grid view on my form that is bound to a data table at run tim. The data table is returned by a function rather than direct from the DB so I can't set the datasource at runtime.
I bind the grid in the page_load event like this:-
Code: Dim _dt As System.Data.DataTable _dt = _srvc.GetVinylShutters(0) _dt.Rows.Add(_dt.NewRow) grdShutters.DataSource = _dt grdShutters.DataBind() (_dt.Rows.Add(_dt.NewRow) is just there to add a blank row in, otherwise I wasn't seeing any columns at all)
I've then got the following snippet which I want to use to hide some underlying columns:-
Code: For Each col As DataControlField In grdShutters.Columns Select Case col.HeaderText Case "OrderID", _ "ShutterID", _ "ModelID", _
[Code] ...
The thing is, wherever I put this it doesn't seem to hide the columns. If I break into the code I can see that grdShutters.Columns.Count equals zero althought I can see that the bound datatable has 38 columns.
I've tried the Page's Load, LoadComplete and PreRenderComplete events as well as the gridview's DataBound, RowDataBound and RowCreated events. I get teh same result in all of them. The grid doesn't actually have any columns until it appears on the screen.
I have a Gridview and I want to hide a column when empty. The code works then the column is in Boundfield but not in Templatefield. Can anyone show me the code of how to do it in Templatefield?
I have a webpage that lists information about trucks and their map sections and whether the combination is active and will be used.
On the page I put a check box that says Show Only Active and marked the checked property as true by default. When the RowDataBound event fires I check to see if that checkbox is marked as true and if it is I check if the individual map sections are marked as active. If they are not active then I set the row visibility equal to false like below.
Then I am adding boundfield to gridview for all 4 columns. Now I want to check if "Type" column contain "Sales" thne do not show "Manager" columns. Let me know can I do this?
but it didn't work and gave me the following error:
Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.TemplateField does not have a DataBinding event.
I tried also to hide it programmatically, but seems I can't reach to the column by name (there's no name for TemplateField column).
I am updating a gridview. Problem is that when I hide certain fields that I do not want the user to update, they lose their values ie. the data is wiped out in the field unless I show them on the grid and make them writeable. Is there a property I need to set for the field to retain the value when the grid is updated or is this in the sql statement?
