Then in this case u can use Regular exp. validators for each textbox..
and also pls update the reg. exp. to "^[0-9]*$"..
and about placing things in table would not make any difference...
|
|
|
|
|
if the text of your textbox(txtnumber) has an empty string it would give the above error, because becomes unable to parse it into integer.

Try this,
Dim str As String=txtseedno.Text
Dim dtrs As Integer=0
If str.Length > 0 Then
dtrs=Integer.Parse(str)
End If
response.write(dtrs)
but, your txtseedno (textbox) should be validate thorough regular expression validator.

Hi,
I have hosted two application sites on two different servers. both the sites are based on windows authentication.
Is there any method by which i can send the credentials used by one site to the other site? so that it will not prompt for the windows useid and password while accessing thr second site from the same window.
( both the sites are using same domain for authenticating users)
any expert comments ...

I have a datagrid as follows which contains a DDL.
<asp:datagrid id="Status_Results" runat="server" Width="656px" Height="50px" PageSize="8" AllowPaging="True" AllowSorting="True">
<Columns>
<asp:TemplateColumn HeaderText="Action">
<ItemTemplate>
<asp:DropDownList id="DDAction" runat="server" OnSelectedIndexChanged="DropDown_SelectedIndexChanged" AutoPostBack="True"> </asp:DropDownList>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
<PagerStyle Mode="NumericPages"></PagerStyle>
</asp:datagrid>
I want to manipulate the contents of DDL dynamically according to results returned.For this I wrote code in Status_Results_ItemDataBound as follows:
<b>DropDownList list=(DropDownList)e.Item.FindControl("DDAction");</b>
list.Items.Add("ABC");
list.DataBind();
But i am getting an error "Object reference not set to instance of an object" at the highlighted line. I am unable to figure out the error.Pls help!!!

It means you should never write code like that. If you call Findcontrol, you should use as and check the result.
DropDownList list = e.Item.FindControl("DDAction") as DropDownList;
if (list != null)
{
// it's OK
}
Then you need to set a breakpoint and look through the controls collection of e.Item to try and work out why it's not in there.

Hi,
I tried your suggestion but it didn`t worked!!!
What i did is...
DropDownList list=e.Item.FindControl("DDAction") as DropDownList;
if(list!=null)
list.Items.Add("ABC");
else
Response.Write("Fail");
and it`s printing Fail implies it`s returning a null value. I saw the same code on a forum (don`t remember which) and implemented it but it`s not workin. Pls help its urgent,i am stuck.....

I'm sorry, your question doesn't make sense, but it looks like you're asking someone to give you a site that you need. We don't do that, we help you when you get stuck trying to write your own site.
