Re-retrieve Data When Paging Using Asp:GridView?
Sep 22, 2011I have a .aspx search screen that displays the results of the search in an asp:GridView component. There can be up to approx 1000 records returned by the search. I want to implememt paging on the grid so that only 15 records are displayed at any one time and the user can page through the results.
I am retrieving the records by passing search parameters to a WCF service which returns a List of particular entity objects. I create a Datatable and insert one DataRow per entity object from the List. I then bind the grid view to the Datatable.
This is how my grid is defined in the .aspx page:
<asp:GridView ID="gridCat" runat="server" AutoGenerateColumns="False" DataKeyNames="CatalogueID"
HeaderStyle-CssClass="fieldHeading" RowStyle-CssClass="fieldContent"
[Code]....
Is there a better way to do this (or am I doing it wrong)? If not, which of the 3 options do you think is the best? I'm leaning towards option 2 as I don't think option 1 is performant and I don't want to be sending loads of unnecessary data back to the browser as per option 3.

Nov 26, 2010I am trying to create a LINQ query statement that retrieve intersecting data from 3 datatables (dt, dt1, dt2). My first attempt to do so with the following LINQ query statement was successful: [code] However in my design, I would need the LINQ query statement to be dynamically generated, because I want a user to be able to retrieve intersecting data entries from VARIABLE number of datatables. In this case, the first option is not as good as the "INTERSECT" query operator, with which I can just easily connect each SQL query statement with a "INTERSECT" operator. The problem is that my second attempt using the "intersect" operator fails, and after many trials and errors I still can't get it to work. [code]
View 5 RepliesVB GridView Control Does Not Allow Code To Access Column When Column Has Visible Property Set To False
Apr 1, 2010VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

Code Behind Gridview Databind How To Retrieve Col Value?
Nov 15, 2011I am databinding my gridview in VB code behind. Because of this I know I can not refer to the NewValues when text is entered into one of the edit boxes. I need to retrieve the value of a column in the RowUpdating event.I have tried to do this in a multide of ways, but each of my changes ends up breaking something else.None of these three methods is working....
Dim DT34 As String = DirectCast(GridView4.Rows.FindControl("Textbox1"), TextBox).Text
Dim TB1 As Label = GridView4.Rows(e.NewEditIndex).Cells(0).FindControl("Label1")
Dim tb1 As TextBox = GridView4.Rows(e.RowIndex).Cells(0).FindControl("TextBox1")
Dim IDVal As String = tb1.Text
In the following code, I am believe it is finding the control but it is not returning the value that was entered into the textbox.
Dim tb As TextBox = DirectCast(GRD4.Rows(index1).FindControl("TextBox1"), TextBox)
updateDescription = tb.Text
My field has been converted to a Template field in the Gridview instead of Boundfield.
