VS 2008 - Programmatically Determine Bindings On Textbox
Jul 9, 2010
I have a method that takes a LINQtoSQL object and a field name and will tell me the length of that field based on the attributes of that field within the class object. I want to use this method to set the maxlength of any bound textboxes in a gridview. I can loop through all textboxes, and if the textbox created from a bound field then i can get at the fieldname ok, however if it's created from a template i can't find any way of getting to the field name the textbox is bound to (since a template isn't bound to anything). What i'm after is a way of getting the field name the Text property of a TextBox is bound to in (ideally) any case, not just the case where it was created from a bound field.
I've added a CKEditor instance programmatically to my page in the code-behind of my ASP.NET page:
VB.NET:
itemEditor = New CkEditor cell.Controls.Add(itemEditor)
... which works fine. I can get the HTML on the postback and do stuff with it.
However, I also want to do some client-side stuff with it, specifically take a selected item out of another control, and insert it into the text by handling the onchange event.
So, how can I get the name of the editor instance in the JavaScript, so that I can do stuff like:
My web application is a product which has to deploy to a variety of web servers. Is there a way to determine the account name that the .Net worker process account is using at runtime?
I have an application that I would like to be able to allow the user to modify multiple characteristics of each record within a datagrid.
Most characteristics require data to be entered in a text box but some a check box would be more appropriate.
My question is does a gridview column need to have all the same item template controls? or could I read from the database the control type and dynamically alter the template control for each row as it loads?
Is there a way where I can actually view the name of a post back element? Below code goves me an alert but all it says is "object HTMLSelectElement". In my case it should be DropDownList3 based upon a "selectedindexchanged" event with autoppostback=true.
Code: var pbControl = null; pbControl = args.get_postBackElement(); alert(pbControl); var ExecutingControl = "DropDownList3" if (ExecutingControl == pbControl) { alert("DropDownList3 - is the post back element");
having trouble defining bindings using ninject.I am in a standard ASP.NET WebForms application. I have defined an http handler to Inject dependencies in pages and controls (Property injection).Here is what I am trying to do:I am creating a custom combobox usercontrol. Based on the value of an enum on that combobox, I want to be able to Inject a different object in a property (What I am trying to do is a bit more involved than that, but answer to this should be enough to get me going).
I am trying to set the color of a textbox that has focus to gray. How can I tell which textbox currently has the curser on it so when they click the change color button it will change the textbox that is focused. Something like this:
I have two textboxes,Suppose I leave the textbox1 empty & press the button,Then alert is there enter value in Textbox1,When the user press ok,Focus is set to dat textbox,I want also to change the backcolor of dat textbox--I think so it is simple,Now when i enter the values in First textbox & press tab to move to second textbox,I wnat the first textbox color to be changed to white.
what the best way to create text boxes in my loop here so that the IDs are unique instead of just "TextBox" for all of them. I need to add up the Price based on the Price per unit and the Quantity.
My items are loaded from a database so there could be any number of them, so I need to generate the fields on the fly. I was thinking maybe an array of fields could be used like in a form application, or is this not the right way to go?
how can I add a dynamic textbox.? I want to add textbox as the user click the add button and then Insert the data from those textboxes in the database.
show give me some codes of creating textbox and recreating them in page load.
in my asp.net_vb code web. there are 9 textboxes whcih is used for entering numerical/dates
first is lve.text in whicj numder is entered
second one is lvefrom.text
thirdone is lveto.text
when user fills (lve.text) 5 and enter 15 Jan 2013 in lvefrom.text then lveto.text should show 19 Jan 2013. i had posted this earlier and got reply which is mentioned below. this code below gives me 20 Jan 2013 instead of 19 Jan 2013.
tw text boxes lve.text (number filled) and lve from.text (date filled). when user enter a numder in lve.text and select a date fro date picker in lvefrom.text then lveto.text should show date selected in lvefrom.text + number of days in lveto.text (eg if number of days is 5 and date selected in lvefrom.text is 15 Jan 2013 then lveto.text should display 19 jan 2013. because the starting day is also counted in my case.
Protected Sub lvefrom_TextChanged1(ByVal sender As Object, ByVal e As System.EventArgs) Handles lvefrom.TextChanged Dim ObjLocDate As New Date Dim IntLocDays As Integer IntLocDays = Convert.ToInt32(lve.Text) ObjLocDate = lvefrom.Text ObjLocDate = ObjLocDate.AddDays(IntLocDays) lveto.Text = ObjLocDate.Date.ToString("dd-MMM-yyyy") End Sub
fourt tex box is pfx.text, fifth is pfx1.text, sixth is pfx2.text
when use filles pfx.text 3 then pfx1.text should display 12 Jan 2013 and pfx2.text should display 14 Jan 2013. these are the prefix for leave( as 12 to 14 Jan 2013 is prefix.seveth is sfx.text, eighth is sfx1.text and nineth is sfx2.text
when user fills sfx.text 3 then sfx1.text should display 20 Jan 2013 and sfx2.text should display.
how to programatically set via javascript the value for a textbox which has a maskededitextender tied to it? tried document.getElementById("textboxid").value but it didnt work.
I'm duplicating a masked textbox in asp.netthe watermark works great, but the maskedtextbox control in windows has a .maskfull property.I want to know if i can check within code (not via html) that the mask has been fully completed.Perhaps I can use the validation extender but can't quite work it out.

I'm using following DropDownList event to select an employee from MS SQL Server 2005 and showing the employee's information on TextBox.
protected void employeeDropDownList_SelectedIndexChanged(object sender, EventArgs e) { EmployeeDAL employeeDAL = new EmployeeDAL(); DataTable dataTable = employeeDAL.GetEmployeeData(); for (int i = 1; i <= dataTable.Rows.Count; i++)......
But the problem is... values of the TextBoxes are not changing. I mean TextBoxes are keeping previous values those were assigned in employeeDropDownList_SelectedIndexChanged event. But why?
I have the calendar extender to popup a calendar when I click in the textbox and works fine. Then I added the maskededit extender so I can make sure they enter the date right. But when i run it, only the maskededit extender is wokring although both are attached.

I have come across something strange. On my web page I have a panel popup with a multiline textbox and a link button. I enter a few lines of numbers in the textbox and submit the link button. I do not get the textbox.text value in the vb code when it posts back to run it.
The label part is for display the information from the database. I'm using a button as a trigger to edit that label by changing it to a textbox and I'll be using another button as a trigger to save the changes made in the textbox and then changing it back to a label.
and I bind the rbl.DataSource to this ListItemCollection. Reviewers comments is a string of html that creates a texbox. I am interested in what is in ReviewersComments as the user can type in here and I need to capture that. The html that is generated looks like this:
