Problem with AjaxControlToolkit CalendarExtender with TextChanged in a datagrid.

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

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[^]

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

A hidden field can be something similar to the input element as suggested in the example below ?

<br />
<script runat="server"><br />
  public void Page_Load(Object sender, EventArgs e)<br />
  {<br />
    // Define the name and type of the client scripts on the page.<br />
    String csname2 = "ButtonClickScript";<br />
    Type cstype = this.GetType();<br />
        <br />
    // Get a ClientScriptManager reference from the Page class.<br />
    ClientScriptManager cs = Page.ClientScript;<br />
<br />
    // Check to see if the client script is already registered.<br />
    if (!cs.IsClientScriptBlockRegistered(cstype, csname2))<br />
    {<br />
      StringBuilder cstext2 = new StringBuilder();<br />
      cstext2.Append("<script type=\"text/javascript\"> function DoClick() {");<br />
      cstext2.Append("var oElement = document.all.Panel1; Form1.Message.value= oElement.offsetLeft;} </");<br />
      cstext2.Append("script>");<br />
      cs.RegisterClientScriptBlock(cstype, csname2, cstext2.ToString(), false);<br />
    }<br />
  }<br />
</script><br />
<html  ><br />
  <head><br />
    <title>ClientScriptManager Example</title><br />
  </head><br />
  <body><br />
     <form id="Form1"<br />
         runat="server"><br />
        <input type="text" id="Message" /> <br />
        <input type="button" value="ClickMe" onclick="DoClick()" /><br />
        <asp:Panel ID="Panel1" runat="server" style="position:absolute;top: 375px;left: 628px;height: 422px;width: 513px;  border-color:Red;border-width:thick;border-style:solid"></asp:Panel><br />
     </form><br />
  </body><br />
</html><br />

1. The pros of "GetLocalResourceObject" and "GetGlobalResourceObject" is to help you achieve

Gloabalization and Localization easily. Cons is that writing code is a little complex than usual.
2. You can use Xml file instead of Resources, as resource itself is in xml format. I would not

suggest you use xml files, because you will lose the ability of using the build-in resource

Localization/Globalization support.
3. The captions of controls should also be get from the resource file.
4. Since .NET 3.5 hasn't been released yet, I do not know whether it will have any new feature on

this.

You can take a look at the following links for more information

You need to have the translation service for that. so, you may develop your own one or you can use the third-party translation web services....

I have 4 DropDownList controls which are used to take the starting time and ending time of a business. I only take hours and minutes for the Starting time.

How can i make use of Javascript here. plz give me some idea/guidance/code sample(if any)

Thanks in advance

You can add javascript like DropDownList.Attributes.Add("OnClick","YourJS()");. Onclick is the event and can be anything applicable to dropdownlist.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Just store the DOB from the text box and use this

it would be simpler for you to calculate age in your database server

like

SELECT DATEDIFF(year, yourbirthdayfield, GETDATE()) AS Age

FROM YourTable

this will return the a field in your query that has the age.
