Hello,

I think I am posting this question again but I'm quite frustrated as I haven't found any way around.

I have a databound datagrid in which New/Blank rows are added to this datagrid on a button click event. This button is outside the datagrid and not in the footer. The datagrid populates well and I can do the edit/update to the already created records. I recently had to add a new checkbox field to my data table. This chekcbox field is to be included in this datagrid. The chkbox works fine for previously created records but as soon as I hit the 'Add New Row' button I get the following error :

Exception Details: System.InvalidCastException: Conversion from type 'DBNull' to type 'Boolean' is not valid.

Source Error:
asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# DataBinder.Eval(Container.DataItem,"currentdriver") %>' />

My code for adding a new/blank row (on button click event) is as below:
RefreshGrid()
Dim ds as DataSet = DataGrid.datasource
Dim blank as DataRow = ds.tables(0).NewRow()

ds.tables(0).Rows.insertAt(blank, ds.tables(0).Rows.Count)
DataGrid.EditItemIndex = ds.tables(0).Rows.Count-1
DataGrid.DataBind()

and my checkbox template column is as below:

asp:templatecolumn headertext="Current Driver?">
itemTemplate>
asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# DataBinder.Eval(Container.DataItem,"currentdriver") %>' />

I really am clueless on this one. everything seems fine. Nulls are allowed on this field in my datatable.Please help!

Thanks.

Try to change your itemplate column to this.

C#

<itemTemplate>
<asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# DataBinder.Eval(Container.DataItem,"currentdriver")== System.DBNull ? false : DataBinder.Eval(Container.DataItem,"currentdriver") %>' />
</itemTemplate>

VB

<itemTemplate>
<asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# Iif(DataBinder.Eval(Container.DataItem,"currentdriver")== System.DBNull, false, DataBinder.Eval(Container.DataItem,"currentdriver")) %>' />
</itemTemplate>

Hello Mark,

A big thankyou for your prompt help and your time to read my post.

I jumped to the solution and did a copy-paste (VB code), but I get the following error :

Compiler Error Message: BC30201: Expression expected.

Source Error:
asp:templatecolumn headertext="Current Driver?">
itemtemplate>
asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" checked='<%# Iif(DataBinder.Eval(Container.DataItem,"currentdriver")== System.DBNull, false, DataBinder.Eval(Container.DataItem,"currentdriver")) %>'
enabled="false" />
/itemtemplate>

what am I doing wrong?

try to replace the logical codition "==" to "=".

VB - Old Code

<itemTemplate>
<asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# Iif(DataBinder.Eval(Container.DataItem,"currentdriver")==System.DBNull, false, DataBinder.Eval(Container.DataItem,"currentdriver")) %>' />
</itemTemplate>

VB - New Code

<itemTemplate>
<asp:checkbox id="cbcurrentdriver" runat="server" autopostback="true" enabled ="false" checked='<%# Iif(DataBinder.Eval(Container.DataItem,"currentdriver")=System.DBNull, false, DataBinder.Eval(Container.DataItem,"currentdriver")) %>' />
</itemTemplate>

Mark

Hi Mark,

Thanks once again for your help. I tried to change the code as per your suggestion above but now I am getting error : BC30691: 'DBNull' is a type in 'System' and cannot be used as an expression.

any ideas?

Thanks.

Thanks MArk, it has worked finally, you were thinking right, just that I had to use 'Is System.DBNull.Value' in place of '==' or '='.

Thanks a ton for your solution, it worked like magic.

<mymultipage:Tab Text="Info2" ID="tab1" ToolTip="Info2"></mymultipage:Tab>				<br />
</mytab:tabstrip><br />
</td><br />
</tr><br />
</TABLE><br />
<br />
<mymultipage:multipage id="MULTIPage1" runat="server" width="780" height="300px"><br />
<mymultipage:pageview id="Info1"><br />
	<TABLE id="ThirdMainTable" cellSpacing="10" cellPadding="0" width="780" border="0"><br />
<br />
	<tr><br />
<br />
	 <td width="10"><br />
         </td><br />
<br />
	 <td width="760"><br />
<br />
	  <TABLE id="tblLocation" cellSpacing="0" cellPadding="0"  width="100%" border="0"><br />
	    <tr height="25"><br />
<br />
 	         <td width="20%"></td><br />
<br />
		  <td width="50%"><br />
<br />
		    <asp:CheckBox id="chk1" runat="server" Text="CheckOnce"></asp:CheckBox><br />
<br />
                  </td>		<br />
<br />
	 	  <td width="30%"></td><br />
<br />
           </TR><br />
         </TABLE><br />
<br />
      </td><br />
    <td width="10"></td><br />
   </tr><br />
   </TABLE><br />

Hi ALL:

I've created a simple web site. There was a Log.aspx page that have hyperlink for user to signup.aspx. By default, ASPNETDB.MDF was created by VS2005. Anyway I got this messaged "Failed to update database "C:\INETPUB\WWWROOT\SQA\APP_DATA\ASPNETDB.MDF" because the database is read-only. "
I'd tried to uncheck the read-only on the folder but didn't help.
Please help!
Thanks in advance.

I have an aspx page I want to pass a Color. How do I do this from another aspx page. I already am accepting some string and int parameters through QueryString. Can I continue to do it that way?

The only way to speed up a Macintosh computer is at 9.8 m/sec/sec.

You can get the color as an integer value using the ToArgb method, and turn the integer back to a color using the FromArgb method.

Hi.

1. Is there any code which will list the installed frameworks on server (asp.net)?

and

2. How can I list all installed browsers on system?

Thanks.

write code to

1.Listout the directories existing in C:\WINDOWS\Microsoft.NET\Framework
2.Check the folder name starts with small v
3.Parse the folder name and take the version.

I know this is a shortcut way of taking the versions. But I dont know how to take it in other way.

Thanks for reply.

Do you think this will work on server since I don't know which letter represents system partition and since I am surely restricted to read Windows folder on server?

Almost i searched for an hour to findout this article. But it is in codeproject only

I saw that article, but uses registry.

I don't think that will work either.

I know that I can see fw version by making an error and then fw version will be displayed, but that isn't very good approach.

Thanks for reply.

Hi.
How can I use a dataview(or any other object that can I edit template it) with paging ?
Gridview has paging but I can't edit template it!

Best wishes

You can use datagridview for paging and editing purpose also.
