Feb 1, 2011
I have placed a list box and a text box with Selected Index Changed and Text Changed event repectively in an aspx page. Now If I write somthing in text box and then with out clicking elsewhere select a value in list box, then first Text Changed event of text box is called then selected Index Change event of list box is called. After that again Text Change event of text box is called. Can any body give some insight why this happening? Below is the .aspx code:

I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.

I have two text boxes and one label control. All three controls are in different "td". Now what i want to do is , i am subtacting a value of textbox2 from the value of textbox1 and storing an answer in label control. I have written a code of subtracting values in the text changed event of textbox 2 and i am also getting an answer in label control. But when text changed event fires, it takes some time to execute which i reall dont like. this is why i want to use update panel to reduce that time. how can i use update panel in this kind of situation. i tried but not successded. so please write some code here related to my controls.

Kindly, see the following image. This is my Gridview with separate paging on the top right of the image. The arrows are Image buttons and the right text box is read only.[URL]
I run my page for the first time everything runs perfect. I move to other pages of the grid still perfect. Then i move to other aspx page and then come back. The page loads perfect with the old page number there still perfect. Now if i press any image button then the text change event fires which should not fire.
Note: i need the text change event as i user randomly enters something in the text box then i have to handle that.
Example:
When i return from the other aspx page then the value in the Page Number text box is lets say 4. Then i press the Back image button and a post back happens. The Value in Text box is still the same 4. Then y the event is firing ???
I am not understanding that why this event is firing. On the page load, i retrieve the values from hash table (The hash table is stored in session in base page) and from the hash table i get the pageNo and assign it to the page No text box.
Here, is my one of the image button event. (Remaining image button events are almost same)

I have an asp page with a textboxes, labels and other controls. I cannot get the .text to change in any of these controls. I click on button which I execute code that I expect to update the text but it doesn't work. Something like Textbox1.text = "Hello" Are there page level properties/settings I should look at? I am perplexed an looking for a place to start. I will provide more information as needed. I just don't know where to start.

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.

I have a component which is listening a server from TCP/IP.
When somebody connects to the system my component's Connected event is fired.
I want to write to a label when this event is fired without postback.
I used UpdatePanel. And I know about AsyncPostBackTrigger.
But my component is not a visual component. So I declared in codebehind. So I can not use AsyncPostBackTrigger.
How can I set my label.text value when component's event runs.

I have a series of textboxes on a FormView. There is a textbox for entering a percent for a deposit amount and next to that a corresponding textbox for entering a dollar value for a deposit amount. There are 3 sets of these.
If a user changes a percent textbox, I update the dollar value textbox based on the percent times the project's total cost. If a user changes the dollar value textbox, the percent textbox gets updated as a percent of that dollar amount divided by the project's total cost.
I have the percent textboxes formatted as "{0:0%}" and the dollar value textboxes as "{0:C}".
When a user types into the textbox, the formatting goes away and we get raw numbers but I don't want those raw numbers to remain as such after they tab or click out of the field. I added a TextChanged event to reset the formatting. This works fine on reformatting the percent textbox but the currency one remains as just a raw numeric value.
Here is the markup (ignore the lack of validation for numeric input only...it will be added):
<td>
<asp:TextBox ID="txtDepositPercent1" runat="server" AutoPostBack="true"
CssClass="TextboxAnimatedRightAlign" Width="33px"
Text='<%# String.Format("{0:0%}", Eval("fld_dep1")) %>'
OnTextChanged="txtDeposit_TextChanged" />

The text change event only fires when I hit enter. It doesn't fire every time I enter a character.
Code:
Protected Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
MsgBox("test")
End Sub

I am dynamically bind the textbox in the data grid and in the text box change event i need to add the numbers in all the text box and show in the separate label.
I am using the text box change event and post back to true, I can able to calculate the result but the problem is that on text change itself i need to calculate and show the result, but in my case, when i move the focus from the that text box, the results calculated and focus get lost.

In my ASP.Net application, I am using ajax accordian control on my aspx page and vb.net for code behind pages.
I have used validation summary for page validation.
1st accordian Pane contains following fields:
First Name
Last Name etc.
2nd accordian Pane contain following fields:
Address
City
Country etc.
while validating the page It displays error messages in following sequence:
Address cannot be blank
City cannot be blank
Country.....
First Name....
Last Name....
But I want to display error messages in following order:
First Name cannot be blank
Last Name....
Address cannot be blank
City cannot be blank
Country.....
I tried to resolve it by giving tabIndex to textboxes and RequiredFieldValidator, but sequence doesn't change I created RequiredFieldValidator again in sequence, but it doesn't affect.

I need to open a txt text an search a sequence data. For example, searching for "name" and get the text NAME: John Doe and return only the "John Doe". An example of the contents of the text:
NAME: EDUARDO MANCIA AGE: 27 ADDRESS: Rua Altino Arantes NUMBER: 297
CITY: SAO PAULO NAME: CARLOS ABREU AGE: 32 ADDRESS: RUA SAO JOSE NUMBER: 1002
CITY: SAO PAULO
There is no standard type of a "name" per line, in fact everything is amended and the file is quite extensive, with 1687 contacts.

{
Label Labelmerchantid = (Label)FindControl("Label1");

I was wondering is it possible to for example have text for example like the following : "product no. 345 - use when loading shedding occurs!"
And lets say this it was saves in StyleSheet1.css as '.useThisProduct'
And then in my label (eg):
<asp:Label runat="server" ID="lableUseThisProduct" CssClass="useThisProduct" />
The reason i am asking I have a list of a few products that may or may not change once a month, and instead of saving all the variables and diffrent things in a sql table I can just update/delete them in a css sheet.
I know I can probably copy and past it in and out of the .aspx page but it just seems so 'un-neat' to have lots of text in the HTML tags.

My form has a RegularExpressionValidator that validates user input in a textbox, like so:
[Code]....
Suppose that the regular expression I want to validate is the standard U.S. Social Security Number which is the following: ^d{3}-d{2}-d{4}$
Now, in order for user input to be valid, it MUST have the two dashes. Therefore, 123-45-6789] would be valid, but 123456789 would not. Well, if the user types in a nine-digit number (in other words, if the following regular expression is valid: ^d{9}$ ), then it's pretty obvious that this is a valid SSN and I want to have dashes get automatically inserted into the textbox before validation of the main regular expression begins. I don't want the user thinking "Hmmm... I don't know if I need the dashes or not." Just put them there if the user didn't type them in, then try to validate. How do I do this?

Obviously I am a total noob and this is simple to some of you, but I can not figure out why the rest of the sub works, but the button1.Text="Uploading, Please Wait..." seems to be completely ignored.
The button is supposed to change text when clicked but no method I have tried works with my page.
Here is my simple upload form page:
