Forms Data Controls :: Old Values Empty In Gridview?

Jan 24, 2011

I'm writing a gridview in VB.NET that is bound programatically in the Page_Load function. I am binding the data in the 'If Not Page.IsPostBack Then..." structure. And as you can see, I'm using TemplateFields instead of BoundFields. And I need to access the e.OldValues in my RowUpdating function, but they come up empty.

Here's my code:

Forms Data Controls :: Handle Null Values Being Assigned To A Calendar Control?

Nov 13, 2010

I've got a detailsview control on a page. The table that it interacts with has a DateTime column in it. This column is nullable, and a lot of the records have null for that value. In the EditItemTemplate I've got a calendar control. When I try to put the DetailsView into edit mode, I get the following error message:

System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.
Source=App_Web_srpmlyjd
StackTrace:
at ASP.entries_aspx.__DataBinding__control44(Object sender, EventArgs e) in c:inetpubwwwrootMediaLibraryEntries.aspx:line 103
at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding)
at System.Web.UI.Control.DataBindChildren()

I am convinced that the problem is the null values in the DateTime column of the table. I've done some web searches on this, and some have suggested placing some dummy values into that column, but that seems more like a kludge, rather than a solution. How do I keep nulls in the table, and yet not have that preceeding error come up when a user tries to edit the selected record?

Forms Data Controls :: Dynamically Binding Dataset Table Values To Datagrid's Header Column?

Jun 29, 2010

I want to dynamically bind dataset values into datagrid's header datafield.

Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.

i.e like ds.Tables[0].Rows[0][0].

Is it possible to do it in Datagrid ItemDataBound function like,

e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]

or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

Forms Data Controls :: Updating The Datasource / Mark All The Values In The Binding Column Of Datasource If Checkbox In Headertemplate Is Checked?

Sep 29, 2010

Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.

My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.

Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.

Forms Data Controls :: Preventing The Display Of Titles For Data Fields If The Data Field Is Empty In ListView?

Nov 14, 2010

I have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this
title if the datafield is empty. Here is what I have done so far.

<ItemTemplate>
<asp:Label ID="BusinessLabel" runat="server" Text='<%# "Tel. "+Eval("Business") %>' CssClass="TeleStyle" />

Or This:Tel.
<asp:Label ID="BusinessLabel" runat="server" Text='<%# Eval("Business") %>' CssClass="TeleStyle" />
</ItemTemplate>

Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?

Why Data Binding Does Not Remember The Old Values

Oct 3, 2010

I have a classic ObjectDataSource and a ListView in my page. The List view just displays some data and when switched to edit template it allows the user to change the values. I want the user to edit just some values -- so I bind just these ones in the edit template.

The problem is that the other values suddenly turn to nulls or 0. I tried to bind all of the values at once and it works fine, but I cannot understand why the old/original values just disappear. Is there any way how to bind the old values?
