You might want to check if the submit has the focus when you hit the Enter. Anyway, in the ASP.NET 2.0, you can have a look at the HtmlForm.DefaultButton Property[^]

To access formview editing element in a class function, I can use the following code:
HttpContext.Current.Request.Form("fvwName$elmName")
How can I access gridview editing row element value in a class function?
|
|
|
|
|
+ Get reference to the Page instance by casting the HttpContext.Current.Handler property to the Page.
+ Get reference to the GridView control using the Page instance and the FindControl method.
+ Get reference to the editable row using the properties of the GridView instance that you have in the previous step.
|
|
|
|
|
Could you please post some code sample?
|
|
|
|
|
Below is the sample code for getting the edit row, and once you have the reference you can easily access the edit values from the cells of the row:
public GridViewRow GetEditRow()
{
Page page = HttpContext.Current.Handler as Page;
GridView gridView = page.FindControl("GridView1") as GridView;
GridViewRow editRow = gridView.Rows[gridView.EditIndex];
return editRow;
}
|
|
|
|
|
When I try your code, I got the following error on line GridViewRow editRow = gridView.Rows[gridView.EditIndex];
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
|
|
|
|
|
That's because I'm using the Edit built-in button in the GridView control so that when I hit the Edit button, the control's mode is changed to the Edit mode and the EditIndex property is set internally. And when the Update button is clicked, I can access the edit row in a seperate class with the above code. I'm not sure when you want to run that code, but if you use your own button, you can raise the Edit command like the built-in button by setting the CommandName as Edit. You might also try to have a look at the EditIndex value at runtime to diagnose your problem. The basic idea is that you need a way to determine the row that is being edited and the index of the row comes to mind as an option.

I have made an ASP.NET 2 website. I compiled it using release setting both in web.config file and in visual studio. I placed the site on the host. My problem is "when an error occures in any page It does not shows detail information about error". It displays the below message.
Even when I set this tag <customErrors mode="Off"/> it again displays that message .Can someone help me please ? How can I fix it ?
---------------------------------------------------------------
Details: To enable the details of this specific error message to be
viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the
current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
--------------------------------------------------------------

Are you sure your host supports ASPNET2?

 Quick question..I am having tough time trying to access a button (from JavaScript function) that is binded to an item template of a datalist control. This datalist is part of a user control (.ascx) and the user control is dragged and dropped on the webpartzone control on the web page. Any suggestions would be appreciated.
I am trying to access this button from JavaScript to do some client side validations.
Thanks.

Hi,
here i have described it for two dropdown list.
Like wise try for 3 drop downlist.
create two dropdownlist as "ddlParent" and "ddlChild".
Populate the "ddlParent" using
if(!Page.IsPostBack)
{
SqlDataAdapter ad = new SqlDataAdapter("SELECT PersonID FROM Person",myConnection);
DataSet ds = new DataSet();
ad.Fill(ds,"Person");
ddlParent.DataSource = ds;
ddlParent.DataTextField = "PersonID";
ddlParent.DataValueField = "PersonID";
ddlParent.DataBind();
}
Now in the selectedIndexChanged event of the "ddlParent" you will implement the code that will fill the "ddlChild".
private void ddlParent_SelectedIndexChanged(object sender, System.EventArgs e)
{
int personID = Convert.ToInt32(ddlParent.SelectedItem.Value);
string query = "SELECT PhoneNumber,PhoneID FROM Phone WHERE PersonID = "+personID;
SqlDataAdapter ad = new SqlDataAdapter(query,myConnection);
DataSet ds = new DataSet();
ad.Fill(ds,"Phone");
ddlChild.DataSource = ds;
ddlChild.DataTextField = "PhoneNumber";
ddlChild.DataValueField = "PhoneID";
ddlChild.DataBind();
}
Hope it will give an idea.
Happy Coding,
With Regards

That's a bit vague. Why do you need a project idea? For what purpose is the project? If it is for your own education, what things are you interested in?

How about a Mars Rover control panel in asp.net
That should be challenging.

Hi,
I'm using a pop-up window to display a contact form. This same window is re-used to contact various departments.
So for example a user clicks a link to contact Department 1, a window pops up with a contact form. Now the user changes their mind and clicks to contact Dept 2. The form is reloaded with the necessary contact details.
The problem here is that the pop-up window is pushed to the background due to the main page doing a postback. I need to be able to bring the pop-up window back to the foreground when this happens / when the content of the pop-up window is reloaded / refreshed.
Can anyone help me with this please?
Thanks!

My Suggestion is better go for AJAX technology instead of posting back your main page.Even if the cotent of the pop window is reloaded it will still remain in the front.There will not be any dependency between Main page and Pop up window.

Put a repeater into your page, define how each row looks and then bind your data from db to the repeater.

a repeater will be a good choice for ur problem. datlist is used if u need to make changes to the data. since u just need some links to another page, it is always better to use repeater.

Hi,
Yes repeater is an good option.
You can do it as:
Code:
qrystr = "select link_text,url from url_links"
adaplnk = New SqlDataAdapter(qrystr, conn)
adaplnk.Fill(drlnk)
y = drlnk.Rows.Count
Repeater2.DataSource = drlnk
Repeater2.DataBind()
Design:
<%if y> 0 then%>
< asp:repeater id="Repeater2" runat="server" >
< ItemTemplate >
< a target="_blank" href="<%#DataBinder.Eval(Container.DataItem, "url")%>" class="popurl" > < IMG height="11" src="images foldername/<%#DataBinder.Eval(Container.DataItem, "link_text")%>" width="14" border="0 >< /a >< /ItemTemplate >
< /asp:repeater >
<%end if%>
