OnPreRender method of GridView control

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :ASP.Net

I was using a reflector and came up on this method OnPreRender() of GridView.

protected internal override void OnPreRender(EventArgs e) 
   if (this.DetermineRenderClientScript() && (this.Page != null)) 
      clientScript.RegisterClientScriptResource(typeof(GridView), "GridView.js"); 

Its calling JavaScript (GridView.js).

Can any one explain the usage of this .js file.

Can we override the file prior rendering of GridView

Using TemplateFields in the GridView Control

The GridView is composed of a set of fields that indicate what properties from the DataSource are to be included in the rendered output along with how the data will be displayed. The simplest field type is the BoundField, which displays a data value as text. Other field types display the data using alternate HTML elements. The CheckBoxField, for example, renders as a checkbox whose checked state depends on the value of a specified data field; the ImageField renders an image whose image source is based upon a specified data field. Hyperlinks and buttons whose state depends on an underlying data field value can be rendered using the HyperLinkField and ButtonField field types.

Reuse a gridview within calendar control


Hello, I have a calendar control that will have events displayed within each cell.

I want to use a pre formatted gridview and simply bind the gridview with a dataset dynamically and display it within the cell of the specified day.

Is there a way to do that or do I have to dynamically build a gridview for every day that there is an event? 

So here is the template gridview and datasource:

 <asp:SqlDataSource ID="sqlcalitemtemp" runat="server" 
        ConnectionString="<%$ ConnectionStrings:NNTrainingdbconnection %>" 
        SelectCommand="SELECT NN_Fire_Events.Start_Time, NN_Fire_Events.End_Time, tblNN_Fire_Cli

GridView EmptyDataTemplate and FindControl Method


I have 2 textboxes, a dropdownlist and a button in the EmptyDataTemplate of a GridView control and when I click the button I want to get the text from the text boxes and DropDownList put it in the QueryString of a URL i redirect to, but I can't work out why the FindControl method cannot find the controls.  I am using the following code:

Dim ddlNumPpl As DropDownList = GridView1.FindControl("ddlNumPpl")

I get an "Object reference not set to an instance of an object" error though when I try to refer to the SelectedValue property of it though.  I would be very grateful if someone could let me know why the FindControl method can't find the control and what I should do to rectify it.

Many Thanks (in advance),


How to format an ItemTemplate value on a gridview control

user control derived from System.Web.UI.WebControls.WebParts only fires its OnPreRender and CreateCh


 I have a application which uses webparts.

So my user controls are derived from System.Web.UI.WebControls.WebParts which makes them webparts.

I have everything setup and working fine as far as the personalization and webpart goes... every thing displays and works fine.

Except that 1 of my control needs to do a bit of work in the OnPreRender event and it turns out that event only gets fired when a user is loged in the application.

So lets imagine that an administrator while logged in switched to 'Sharedscope' within the webpartmanager and then has added the usercontrol/webpart 'calendar' to the top webpart zone. This then makes the 'calendar' control viewable by all and any user who visits the page wheter logged in or anonymous.

And this works fine and very well as it is supposed to. However in the 'Calendar' user control which is derived from System.Web.UI.WebControls.WebParts I have an overiden 'OnPreRender' event like this:

Protected Overrides Sub OnPreRender(ByVal e As EventArgs)

If Not Me.DesignMode Then

Me.isloaded = True

' Test for ScriptManager and register if it exists

sm = ScriptManager.GetCurrent(Page)

If sm Is Nothing Then _

Throw New HttpException("A ScriptManager control must exist on the current page.")
