In the properties for the web application in IIS, you can choose what version of the framework the application uses.
---
b { font-weight: normal; }

|

Yes, I changed version of framework ASP.NET 1.0 web uses, but they can't run on both 1.0 and 2.0.

For your textbox in the code behind:
myDropDownList.Attributes.Add("onclick", "EnableTextBox;");
In javascript on the page:
function EnableTextBox()
{
document.forms[0].myTextBox.disabled = false;
}

Hi all. How can i validate a date in format of DD/MM/YYYY using regularexpressionvalidator control? please help me out.
|
|
|
|
|
Use this pattern: "\d{2}/\d{2}/\d{4}".
This will of course only verify that the format is correct, it can't verify that the date actually exists. You can make the verification a bit better by making sure that the date is in the range 1 to 31 and so on, but still that won't see that a date like 31/02/2006 does not exist.

b { font-weight: normal; }

You can use the CompareValidator with the DataTypeCheck operator and Type="Date" to validate if the textbox value is a valid date. You also should remember that the date format used by the validator is specified based on the current culture value when the validator control renders, for example if the current culture is set for the "en-GB" value, then the dateorder will be mdy, and the validator will accept the values like 18/4/2006 or 18/04/2006 ..., the delimiter can be either - or /. If you want to use the fixed format like you said, you can either implement a custom validator for this or use an additional RegularExpressionValidator with the pattern suggested by Guffa. For more information on how to set the culture value, you can see MSDN[^]

Use Compare Validator that would be correct solution in this scenario

Hi
I currently have a paging mechanism for my datalist control which is displaying a gallery of Images. The code is a modified version of the code from HERE. I would like to modify the control to allow for paging through the images similar to the paging mechanism found on google. Only, there will be a fixed number of pages displayed and there will be a next and previous button as well.
<< Prev 1 2 3 4 5 Next>>
So far what I've been able to achieve is: I am able to page through pages 1 to 5, in any order. All the buttons are linkbuttons.
Here is what I need to still do:
1. Allow the next button to move through the currently displayed pages
2. When the user is on the last page and clicks the next button, the next page needs to be displayed and the linkbuttons need to change to show the next 5 page numbers too.
Can anyone help me as to how I can go about starting this or if anyone else has done this or is busy with a similar thing, please, any and all help will be brilliant.
Thanks

You can't use ASP.NET to change the input as the user writes it, only to change it once it's posted to the server. You have to use Javascript to change the text in the textbox.

b { font-weight: normal; }

pls give any sample code.
I think using textbox.attributes will help for this(i don't know exactly)
thanks

You can just put this line into your code behind (my asp textbox was just the default "TextBox1":
this.TextBox1.Attributes.Add("onkeyup","this.value = this.value.toUpperCase();");

i want to traverse through a treeview web control and fetch the ID's of all checked nodes.
that is, all those nodes whose checkboxes are checked in a treeview.i want to get their Id's.
i've used the following code :
''' For getting selected contact id's from the Group Tree
Function GetContacts() As ArrayList
Dim mnode As Microsoft.Web.UI.WebControls.TreeNode
Dim contacts As New ArrayList
Viewstate("ContactCounter") = 0
For Each mnode In TV_MasterContactList.Nodes
GetSelectedContactID(mnode.GetNodeIndex, contacts)
Next
Return contacts
End Function
Sub GetSelectedContactID(ByVal Tnode As String, ByRef Contacts As ArrayList)
Dim nnode As Microsoft.Web.UI.WebControls.TreeNode
If TV_MasterContactList.GetNodeFromIndex(Tnode).Type = "Contact" And TV_MasterContactList.GetNodeFromIndex(Tnode).Checked = True Then
Contacts.Add(TV_MasterContactList.GetNodeFromIndex(Tnode).ID)
End If
For Each nnode In TV_MasterContactList.GetNodeFromIndex(Tnode).Nodes
GetSelectedContactID(nnode.GetNodeIndex(), Contacts)
Next
End Sub
but its not giving the correct result
regards,
Kapil

So what does it give you? Do you assign the ID value which you expect to receive to the ID property of the TreeNode?
|
|
|
|
|
when i check some checkboxes and on button click call these functions to retrieve the checked checkboxes Id.
it shows even the checked checkboxes as unchecked and thus doesnt returns any Id's
|
|

You might want to debug your application and try to step through your sample code line by line. Also, i'm curious that why you don't just use the TreeNode instance from the Nodes collection instead of using the GetNodeFromIndex method. Anyway, below is a quick example for this:
private ArrayList GetContacts()
ArrayList Contacts = new ArrayList();
foreach(TreeNode node in TV_MasterContactList.Nodes)
{
GetSelectedContactID(node, Contacts);
}
return Contacts;
}
private void GetSelectedContactID(TreeNode node, ArrayList Contacts)
{
if(node.Checked)
Contacts.Add(node.ID);
foreach(TreeNode child in node.Nodes)
{
GetSelectedContactID(child, Contacts);
}
}

Usually to change a controls Property using script I just use ID.Property = "What I want"
But BoundField doesn't have an ID so now what?
|
|
|
|
|
You can access the field using the Columns collection of the GridView or the Fields collection of the DetailsView, that depends on which control you use.

Hi I have a problem with binding parameters to an update command for an asp:SqlDataSource. The problem is when I am trying to bind a ASP:CheckBox field.
I have this definition
<asp:FormView ID="HomeListingForm"
runat="server"
DataSourceID="SqlHomeListing"
BackColor="#DEBA84" BorderColor="#DEBA84" BorderStyle="None"
BorderWidth="1px" CellPadding="3" CellSpacing="2" GridLines="Both"
DefaultMode="Edit"
>
<EditItemTemplate>
<table>
…………….
<tr>
<td >
<asp:CheckBox ID="ckMealsAvailable" Text="Meals Available" Checked ='<%# Convert.ToBoolean(Eval("MealsAvailable")) %>' runat="server" />
</td>
<td >
<asp:CheckBox ID="ckPrivateLivingArea" Text="Private Living Area" Checked ='<%# Convert.ToBoolean(Eval("PrivateLivingArea")) %>' runat="server" />
</td>
</tr>
</table>
---------
</asp:FormView>
<asp:SqlDataSource ID="SqlHomeListing" runat="server"
UpdateCommand ="UPDATE HomeListing SET AddressLine1 = @AddressLine1, AddressLine2 = @AddressLine2, City = @City, PostalCode=@PostalCode, ProvinceId = @ProvinceId, PrivateLivingArea = @private_living_area WHERE ListingId = @ListingId"
ConnectionString ="<%$ …….. %>" >
<UpdateParameters>
<asp:FormParameter Name="AddressLine1" Type="string" FormField="AddressLine1" DefaultValue =""/>
<asp:FormParameter Name="AddressLine2" Type="string" FormField="AddressLine2" DefaultValue = "" />
<asp:FormParameter Name="City" Type="string" FormField="City" DefaultValue =""/>
<asp:FormParameter Name="PostalCode" Type="String" FormField ="PostalCode" DefaultValue =""/>
<asp:FormParameter Name="ProvinceId" Type="Int32" FormField ="Province" DefaultValue ="0"/>
<asp:FormParameter Name="private_living_area" FormField ="ckPrivateLivingArea" Type="Int16" />
<asp:SessionParameter DefaultValue = "0" Name="ListingId" Type="String" SessionField="ListingId" />
</UpdateParameters>
</asp:SqlDataSource>
I am getting this error; Cannot insert the value NULL into column 'PrivateLivingArea', table 'RentalProperty.dbo.HomeListing'; column does not allow nulls. UPDATE fails.
The statement has been terminated.
I know what it means but I can not figure out how to bind this checkbox field to the query parameters
