I want to change the color of my background on a textbox when the user typers stuff. For example I have two textboxes password and confirm password. On the second one if the passwords match I'm going to make the back color white if not red.
I can do this on WinForms easy as, same code on Web Forms and nothing happens. How do i do this???
I'm trying to read the contents of a text file into a text box on my form. When I run the following code, nothing happens.
VB.NET Code:
Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object,
ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged
For Each li As ListItem In lbLogs.Items
If li.Selected Then Using sw As New StreamReader(li.Value)
txtLog.Text = sw.ReadToEnd sw.Close() End Using End If Next End Sub
I populate the ListBox with ListItems and each ListItem's Value property holds the full path to the file. But, I removed all of that and just put txtLog.Text = "test" inside of the "is selected" block.
I have a list box with data coming from the database. Above the list box I have a text box. If the user enters some text in the text box,then the data in the list box should be filtered as per the content entered in the textbox. In my page, i have about 7-8 such similar textboxes and listboxes. So I want to implement a common function which can be used for all the text boxes in the page. I tried to achieve this in textchanged event and javascript but sometimes not working. Is there any other simple way except javascript? Is it efficient to use java script in this scenario? Need your valuable inputs.
View 6 RepliesI have a select box in an asp.net form like so:
[code]....
This way I can set a session variable with the same name in Process.aspx:
[code]....
, and then set the value of the select box when the user returns later like so:
string referer = (string) Session["referer"];
foreach (ListItem i in refererSelect.Items)
if (referer == i.Value)
i.Selected = true;
The problem is when the form is sent to the server, the form key gets changed to "ctl00$content$refererSelect". Is there any way to fix this?
I am using SelectedIndexChanged in the DropDowList and it works fine and populates a GridView based upon a site selection.
Is there there a way I can reset the SelectedIndexChanged so if user wants to refresh the GridView they would open the drop down list and click on the same selection again?
I've searched high and low for a efficient and reusable way to detect, on a postback/server-side, if any input controls on a form have been changed and I haven't found anything other than client-side solutions such as DirtyUpdatePanelExtender. I've come to the conclusion that it must be either really simple or really complicated.Ultimately what I want to do is to perform a database update, or not, depending on whether or not the user has changed any input controls on the form. The only thing I've come up with so far is to save the original values as Viewstate variables and then compare them with the Request values on a postback, but that seems far from ideal.
View 9 RepliesI have an aspx page in which the code-behind is in VB.Net. I have a TextBox field on my page. In the code-behind, the only event that I have for this field is the TextChanged Event. However, whenever I enter data into the TextBox field, the event won't fire. What would prevent this from happening?

I have 7 textboxes. If Top 1 textbox(Volume All Years) text changed, text need to be updated in next 6 inputboxes(Latest 2009 Volume to Latest 2014 Volume). I need javascript or Jquery for this. I will write Js textchanged() or focuschange() for top 1 textbox. So what should I write in focuschage() or textchanged methods().
I changed little bit in code. Now Html will like below. These textboxes have common CssClass. volumetextbox. Can we use this class and change text in all textboxes those have same CssClass.

I have come unstuck with a simple compare validation.
I have the following code
<asp:TextBox ID="tbxHowMany" runat="server"
style="z-index: 1; left: 310px; top: 385px; position: absolute; text-align: center;"
Width="75px"></asp:TextBox>[code]....
So when a user enters a figure higher than 200, the validation appears.However, when I change this figure to say, 30, the validation remains. I must be doing something really stupid, I just don't know what!
UPDATE: I have also just noticed that this validation occurs when a number greater than '20' is entered into the checkbox. I'm not very confused. I am assuming this is a type issue?
I have a bunch of controls in a Content Page ( A registration page, right) to gather information concerning a user. One of controls is for the UserName. I want to check that the UserName is unique so I place code in the TextChanged event of the TextBox control for the UserName. I have abreak point set in the event procedure and it never gets hit! This is my first attempt at using Master/Content pages. I have looked in the MSDN Library for many hours concerning this problem without any success. I need to know how to check whether the UserName is currently in an Access database.
View 5 RepliesI am calculating discount at text changed event when user enters the discount%.

I am getting it as 500000. Instead of 5000.00. Is it because of text changed event? How do i resolve this?

I've a textbox in grid view control. When user inserts some value in textbox a confimation message should be displayed to user. eg. "Do you want to update record?". if user clicks on yes/ok then some code should be executed else if user clicks cancel/no the return to same page. I've tried using
ScriptManager.RegisterClientScriptBlock(page, page.GetType(), "key2", "confirm('Do you want to update?');", true); on text changed event of textbox. But was not able to achieve desired result.
I'm new to ASP.net 3.5 and testing functionality before developing an asp.net web site. I created a page with a formview. I added several text boxes. I created an event on the FirstName_TextChanged event and added a stop in the sub. When I open the page in the browser and type in some text in the FirstName and press tab, nothing seems to fire.
1) Is this supposed to fire on the client side when text is changed?
2) If so, would the vb.net code entered work like Javascript code on the server?
3) If so again, is it possible to update another textbox based on the text entered into the FirstName on the Client Side (would do this in Javascript in Classic ASP)?
I think I'm totally confused. I've been searching web for article about how to do this.
I have a gridview that is being databound by an SQLdatasource and on RowDataBound i am doing a calculation and then setting
e.Row.cells(17).text = Result
However, when I go to sort it on the website it sorts it based off the previous values.Cell(17) from the datasource reads in all 1's. The numbers I change it to range from 0 to 15. So when I click sort nothing changes because it sees it as all 1's.How can i make the gridivew sort off the changed text values?
