Using a field mask and forcing the cursor to the left

This is not identical to this question, but it's very similar.
I'm using ASP.Net and need to more or less do the same thing, but was hoping it can be done on the ASP side.
My relevant code is such:
<td style="line-height: 230%;">
<asp:TextBox ID="txtePro" runat="server" CssClass="textbox" Font-Size="Small" Height="18px" Width="100px" Visible="False" Wrap="False" OnTextChanged="txtEPro_OnLeave" AutoPostBack="true"></asp:TextBox>

As in the linked question, my problem is that when a user clicks inside the text box, they're sometimes starting in the middle and I need the cursor to be forced all the way to the left. Is there a way to force the cursor all the way to the left from within ASP, or is this something that can only be done in the code-behind?

You can achieve that using javascript and jQuery by setting the SelectionRange to 0,0 on the mouseup event:
$(document).ready(function(){
$(".resetCursor").mouseup(function () {
this.setSelectionRange(0,0);
});
});
http://jsfiddle.net/6m8stbo7/1/
Then add the class resetCursor to the TextBox Controls you want to extend with this behavior.
<asp:TextBox ID="txtePro" runat="server"
CssClass="textbox resetCursor"
Font-Size="Small"
Height="18px"
Width="100px"
Visible="False"
Wrap="False"
OnTextChanged="txtEPro_OnLeave"
AutoPostBack="true">
</asp:TextBox>
Explanation:
resetCursor is a css stylesheet class that is used by jQuery to select the specific DOM-Elements. It is common practice to use css classes to "declare" certain behavior on a set of DOM-Elements and then use jquery to "activate" that behavior in one go. Edit: Note that resetCursor is an arbitrary name, you could have chosen another name as you please.
Here is a good introduction to the basic jQuery selectors (I'm using the Class-Selector in this example):
http://api.jquery.com/category/selectors/basic-css-selectors/

This answer uses jQuery - I hope you know it, otherwise this no good:) In case you know it - using answer by Ovm2 just fix your ASP.NET markup like CssClass="textbox resetCursor" or do it programmatically with jQuery with .addClass() so
$(document).ready(function(){//once DOM is loaded
$(".textbox").addClass('resetCursor');
$(".resetCursor").mouseup(function () {
this.setSelectionRange(0,0);
});
});
In case you aren't familiar with jQuery - well, you have to start learning it asap!:)
P.S. Initially I intended to add the comment to answer by Ovm, but I failed to format code sample with mini-markup there. And don't forget to learn\refresh info about using CSS selectors as this is the ultra important, well, it is simply essential for having good times not only with jQuery, but with HTML at all. Hope that helps:)

You can use createTextRange method in javascript to move cursor postion. Following function will help you to move position to start.
function setCaretPosition(elemId) {
var inputEle = document.getElementById(elemId);
if (inputEle != null) {
if (inputEle.createTextRange) {
var range = inputEle.createTextRange();
range.move('character', -1);
range.select();
}
else {
if (inputEle.selectionStart) {
inputEle.focus();
inputEle.setSelectionRange(0, 1);
}
else
inputEle.focus();
}
}
}

You can use TextMode="Multiline" property for Textbox

Checkbox checked issue in grid view

In the below code i have a grid view in which i have a textbox i am passing 0 and 1 to check box if it is 1 the checkbox to be checked.I tried but it is not working.Pls help me to solve the issue.
<asp:TemplateColumn HeaderText="Sales Price Ref" ItemStyle-Width="200px" HeaderStyle-VerticalAlign="Top">
<HeaderTemplate>
<asp:Label ID="lblSalesPriceRef" runat="server" Text="Sales Price"></asp:Label>
<br /><br />
<asp:TextBox runat="server" ID="txtSalesPriceRef" AutoPostBack="true" BorderStyle="Solid" BorderColor="#6495ED" BackColor="#B0C4DE" Height="20px" Width="90px" OnTextChanged="txtItem_TextChanged"></asp:TextBox>
</HeaderTemplate>
<EditItemTemplate>
<asp:CheckBox ID="ChSalesPriceRef" runat="server" Checked='<%#Eval("SalesPriceRef")=="1" ? true:false %>' />
<%-- <asp:TextBox ID="txtSalesPriceRef" Width="90px" runat="server" Text='<%#Eval("SalesPriceRef") %>'></asp:TextBox>--%>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblSalesPriceRef" runat="server" Text='<%# Convert.ToString(Eval("SalesPriceRef"))== "1" ? "True" :"False" %>' > </asp:Label>
</ItemTemplate>
</asp:TemplateColumn>

YES you can achieve it by binding it to the checkbox
as
<asp:CheckBox ID="ChSalesPriceRef" runat="server" Checked='<%# Bind("SalesPriceRef")%>' Enabled="false" />
if you allow to change checkbox value then make enable=true

DetailsView and EditItemTemplate

me problem is next:
I have a DetailsView control with many editItemTemplates some work fine but i have one dont work's.
code here:
<asp:TemplateField HeaderText="Date" SortExpression="date">
<ItemTemplate>
<%#this.putDate(Eval("fecha")) %>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="date" runat="server" ></asp:TextBox>
<asp:CalendarExtender id="CE" runat="server" Format="dd/MM/yyyy"
PopupButtonID="calImg" TargetControlID="date">
</asp:CalendarExtender>
<asp:ImageButton id="calImg" runat="server" CommandName=""
ImageUrl="img/imgCal.gif" />
</EditItemTemplate>
</asp:TemplateField>
In view mode the information appear right but in edit mode after select new date with calendar and pres accept to update information, the data dont update. Any idea?

Replace:
<asp:TextBox ID="date" runat="server" ></asp:TextBox>
With:
<asp:TextBox ID="date" runat="server" Text='<%# Bind("SelectedDate") %>'></asp:TextBox>

Error: 'this._targetEl.value.length' is null or not an object ASP.NET

I'm trying to bind the selected value from the date picker to an asp textbox but I have this Error: 'this._targetEl.value.length' is null or not an object.
Here's the code:
<InsertItemTemplate>
Book Title:
<asp:DropDownList ID="DropDownList1" runat="server"
DataSourceID="booktitleDataSource" DataTextField="booktitle"
DataValueField="bookid" SelectedValue='<%# Bind("bookid", "{0}") %>'>
</asp:DropDownList>
<asp:SqlDataSource ID="booktitleDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:LibrarySystemConnectionString %>"
SelectCommand="SELECT [bookid], [booktitle] FROM [TblBooks]">
</asp:SqlDataSource>
<br />
Employee PIN:
<asp:TextBox ID="employeeidTextBox" runat="server"
Text='<%# Bind("employeeid") %>' />
<br />
Department:
<asp:TextBox ID="departmentTextBox" runat="server"
Text='<%# Bind("department") %>' />
<br />
Date borrowed:
<asp:TextBox ID="dateborrowedTextBox" runat="server" Text='<%# Bind("dateborrowed") %>' />
<%--<input type="text" name="dateborrowedTextBox" readonly="readonly" id="dateborrowedTextBox">--%>
Date Picker
<br />
<asp:Button ID="InsertButton" runat="server" CausesValidation="True"
CommandName="Insert" Text="Insert" />
<asp:Button ID="InsertCancelButton" runat="server" CausesValidation="False"
CommandName="Cancel" Text="Cancel" />
</InsertItemTemplate>
It was working when I
tried using <input type="text" name="dateborrowed" readonly="readonly" id="dateborrowedTextBox"> but when I tried using the asp:TextBox I cant pass the selected value from date picker to the textbox. So where did I go wrong? Is there a way to program the date picker link to call the popup calendar? (its in Java btw)
Help would be much appreciated!
Thanks in advance.

Nested controls have their ID/name attributes overwritten with an absolute unique id/name when rendered. When your javascript is attempting to reference the TextBox its name won't actually be 'dateborrowedTextBox' it will be something like '...$ctl00$dateborrowedTextBox'.
If your javascript is finding the control by name, this might clear up the issue:
Date Picker
Otherwise try this if its finding the control by id:
Date Picker

Found the solution. I think it can only read asp.net syntax not classic asp.
<asp:TextBox ID="reservedateTextBox" runat="server" Text='<%# Bind("reservedate") %>' />
<%--Date Picker--%>

Binding a Java Date Picker to a textbox in formview ASP.NET C#

I'm having some problem binding the value of a date picker to a textbox in formview asp.net. I've tried to a put a date picker in ASP.NET and JavaScript which calls on a class file in calendar.css so far it can display the date but if I tried to insert it to a record it always return null. So how can I bind it so it can add the date value to the record?
Help would be much appreciated.
Thanks in advance ;)
Here's a sample of my code. I want to bind the 'input text' to the 'dateborrowedTextBox'
<InsertItemTemplate>
Book Title:
<asp:DropDownList ID="DropDownList1" runat="server"
DataSourceID="booktitleDataSource" DataTextField="booktitle"
DataValueField="bookid" SelectedValue='<%# Bind("bookid", "{0}") %>'>
</asp:DropDownList>
<asp:SqlDataSource ID="booktitleDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:LibrarySystemConnectionString %>"
SelectCommand="SELECT [bookid], [booktitle] FROM [TblBooks]">
</asp:SqlDataSource>
<br />
Employee PIN:
<asp:TextBox ID="employeeidTextBox" runat="server"
Text='<%# Bind("employeeid") %>' />
<br />
Department:
<asp:TextBox ID="departmentTextBox" runat="server"
Text='<%# Bind("department") %>' />
<br />
Date borrowed:
<%--<asp:TextBox ID="dateborrowedTextBox" runat="server"
Text='<%# Bind("dateborrowed") %>' />--%>
<input type="text" name="dateborrowedTextBox" readonly="readonly" id="dateborrowedTextBox">
<a href="#" onclick="cdp1.showCalendar(this, 'dateborrowedTextBox'); return false;">Date Picker
</a>
<br />
<asp:Button ID="InsertButton" runat="server" CausesValidation="True"
CommandName="Insert" Text="Insert" />
<asp:Button ID="InsertCancelButton" runat="server" CausesValidation="False"
CommandName="Cancel" Text="Cancel" />
</InsertItemTemplate>

The client-side IDs of the ASP.NET controls are not going to be translated as cleanly as you are hoping.
You need to do one of two things, both of which can be found here.
Date Picker
Or, you could add a Link control and set the actions that way (the link I gave you does it with an image control). It's up to you.

Just found my answer. ASP.NET cant read Javascript normally so CT100 and some dollar sign will do the trick ;)
