Others on the same network (and you yourself) should be able to see it by replacing "localhost" with your computer's name. You may need to configure your network/OS firewall to allow HTTP requests.

Setting Focus on a TextBox and sellecting the text in a DataGrid with TextChanged

thomasa6-Dec-07 4:39

I have a datagrid containing 2 coulmns with 1 TextBox in each.

On the first TextBox I have a TextChanged event.
After the event is fired I want to set Focus on the next textBox, and sellect the text on it.

<br />
private void OnSubscriptionToValueChanged(object sender, System.EventArgs e)<br />
        {<br />
            TextBox tb = (TextBox)sender;<br />
            if (tb.Text.Trim() != "VAT")<br />
            {<br />
tb.CssClass = "tbStyle0";<br />
                    DataGridItem dgi = (DataGridItem)tb.Parent.Parent;<br />
TextBox tbToFocus = (TextBox)dgi.FindControl("tbNextValue");<br />
tbToFocus.Focus(); // Here it sets focus but it don't select the test<br />
}<br />
else<br />
            {<br />
                tb.Focus(); // Here it sets focus but it don't select the test<br />
                tb.CssClass = "tbStyleError";<br />
}<br />
}

The code over sets Focus on the control I want, but it don't select the text (as it would if the TextChanged event
wasen't there when you tab from one TextBox too another).

Has anyone an idèe how to do that?
Thanks
Thomas

Page.RegisterStartupScript("focus", "<script>document.getElementById('" + tbToFocus.UniqueID + "').focus();</script>");
Page.RegisterStartupScript("select", "<script>document.getElementById('" + tbToFocus.UniqueID + "').select();</script>");

Visual Studio 2005 says that the function is absolite, so one should rather use:

Page.ClientScript.RegisterStartupScript(GetType(), "focus", "<script>document.getElementById('" + tbToFocus.UniqueID + "').focus();</script>");<br />
                        Page.ClientScript.RegisterStartupScript(GetType(), "select", "<script>document.getElementById('" + tbToFocus.UniqueID + "').select();</script>");                             <br />

And to expand on your solution. You should just strip off the <script> tags and add a fourth parameter with the value of true. This will ensure that the <script> tags are added automatically with the type attribute of the tag set to text/javascript which will make the output XHTML compliant.

Page.ClientScript.RegisterStartupScript(GetType(), "focus", "document.getElementById('" + tbToFocus.UniqueID + "').focus();", true);<br />
Page.ClientScript.RegisterStartupScript(GetType(), "select", "document.getElementById('" + tbToFocus.UniqueID + "').select();", true);

how to detect whether the requesting machine is a mobile?

hi
I want to redirect the user to a mobile form when the requesting machine is a mobile irrespective of whether it has Pocket IE or some really ordinary browser.

<br />
Dim res As String = Request.Browser("IsMobileDevice")<br />
If res = "false" Then<br />
            'when its a desktop machine requesting the page<br />
            Response.Redirect(when_Desktop)<br />
        Else<br />
            'when its a mobile<br />
            Response.Redirect(when_Mobile)<br />
 End If<br />

Later I tried this code but it failed. I think HTTP headers help u to identify the model of the mobile. I just wanna know whether its a mobile or not.

How can I do it?

Thanks

Rocky

A piece of advice, mr/s beginner:

people here will be glad to help with specific prohlems, but we are not here to do your work for you. There is a very good website called Google[^] which is invaluable for finding things out. For example, try searching for "asp.net file upload"...

Hi AccessRed,

I think you are very new in our forum. So, I would like to give you one suggestion. If you want to do something, don't forget to search in Google.

<a href="http://www.google.com/search?q=asp.net+file+upload&rls=com.microsoft:*:IE-SearchBox&ie=UTF-8&oe=UTF-8&sourceid=ie7&rlz=1I7SUNA">ASP.NET File Upload</a>[<a href="http://www.google.com/search?q=asp.net+file+upload&rls=com.microsoft:*:IE-SearchBox&ie=UTF-8&oe=UTF-8&sourceid=ie7&rlz=1I7SUNA" target="_blank" title="New Window">^</a>]

You can read those articles and try to test in your machine.. then, you will understand more about how things work. After that, if you are still facing the problem, you can come back here and ask the specific question. I think that the first link from the Google result that I gave you might solve your problem. Good luck.

Thre is no reason why moving files or renaming directories should, in itself, end your session - there must be some other reason why this is happening.

Problem with AjaxControlToolkit CalendarExtender with TextChanged in a datagrid.

thomasa6-Dec-07 2:20

I have a datagrid with an CalendarExtender conected to a TextBox in a DataGrid

<br />
asp:datagrid id="dgSubscription" runat="server" CssClass="grid" AllowPaging="False" CellPadding="0"<br />
		                        GridLines="Vertical" AutoGenerateColumns="False" ShowFooter="true" OnItemCreated="dgSubscription_ItemCreated"><br />
<br />
Columns><br />
asp:TemplateColumn HeaderText="Date" HeaderStyle-HorizontalAlign="Left" ItemStyle-Width="150px"><br />
				                       				                        ItemTemplate><br />
asp:TextBox ID="tbDtmStart" runat="server" AutoPostBack="true"></asp:TextBox><br />
				                            <cc1:CalendarExtender ID="ceStart" runat="server" Format="dd.MM.yyyy" TargetControlID="tbDtmStart" SelectedDate='<%#(DateTime)DataBinder.Eval(Container.DataItem, "dtmStart")%>'><br />
                                            </cc1:CalendarExtender>	<br />

I have an on item created in the code behind, hver I add a TextChanged event to the Date TextBox

<br />
 protected void dgSubscription_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)<br />
        {<br />
try<br />
            {<br />
                if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)<br />
                {<br />
                    <br />
                    // Start date<br />
                    tb = (System.Web.UI.WebControls.TextBox)e.Item.FindControl("tbDtmStart");<br />
                    tb.TextChanged += new EventHandler(this.OnSubscriptionDtmStartChanged);<br />
<br />
.....<br />

At first time the page load, the DataGrid.DataSource gets it values from
a dataview.

The problem is that the OnSubscriptionDtmStartChanged is
triggerd for every row in the DataGrid, because the CalendarExtender changes the TextBox's value.

There is allso a problem that the OnSubscriptionDtmStartChanged funtion i triggered 2 times
when I change the value on one of the DataGridRow.

I know that all of this has to do with the CalendarExtender changes the TextBox's value,
but can I some how get around this?
Thanks
Thomas

The problem was that I binded the Date to the CalendarExtender as:

<cc1:CalendarExtender ID="ceStart" runat="server" Format="dd.MM.yyyy" TargetControlID="tbDtmStart" SelectedDate='<%#(DateTime)DataBinder.Eval(Container.DataItem, "dtmStart")%>'><br />

All of my problems went away when I insted:

asp:TextBox ID="tbDtmStart" runat="server" Text='<%#((DateTime)DataBinder.Eval(Container.DataItem, "dtmStart")).ToString("dd.MM.yyyy")%>' AutoPostBack="true"></asp:TextBox><br />
				                            <cc1:CalendarExtender ID="ceStart" runat="server" Format="dd.MM.yyyy" TargetControlID="tbDtmStart"><br />
                                            </cc1:CalendarExtender>

I think you need to do a brave bit more reading...

I think you want to execute your dataset using a SqlCommand object and then iterate through the results using a SqlDataReader.

You might want to have a look at the MS application block for data access, simplifies things a little:http://msdn2.microsoft.com/en-us/library/aa480458.aspx[^]

calling javascript from c#

hi guys,

I am stuck on the issue of being able to call a javascrip function from my c# code.
This is my javascript:

<br />
  <SCRIPT LANGUAGE="JScript"><br />
    function showPosition()<br />
    {<br />
        var oElement = document.all.resultPanel;<br />
        return oElement.offsetLeft;<br />
    }<br />
  </SCRIPT><br />

The javascript itself works fine, the problem comes down to how do I call my javascript in c#. This was my attempt:

<br />
        private void CallJavascript()<br />
        {<br />
            string popupScript = "<SCRIPT LANGUAGE='JScript'>" + "function showPosition(){ var oElement = document.all.resultPanel; return    oElement.offsetLeft;}</SCRIPT>";<br />
            Page.RegisterStartupScript("PopupScript", popupScript);<br />
            Label1.Text = popupScript.ToString(); //this is wrong<br />
        }<br />

Can someone please help me correct the CallJavascript() method.

thanks
