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 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" />

I'm allowing a user to use either one of two textboxes to search a database - one is an ID field, and one is a freetext field. I'm using ASP.NET with C# btw.Anyway, all I need to do is have it so when a user clicks on one of the text boxes, the other text box text is simply deleted, so the other text box is blank. How would I do this? I'm guessing JavaScript is the solution.

What happens is that the page is left with just the watermark text, but not the text I'm setting it to. However, if I inspect the textbox in VS it says the text is what it's supposed to be.

I have a Telerik:RadTextBox control in my markup called txtName. I'm trying to retrieve the inputed value in the code behind with foo = txtName.Text; but var and txtName always show an empty string.
Markup
<telerik:RadTextBox ID="txtName" Runat="server" Width="300px" />
CodeBehind
campaign.Name = txtName.Text.Trim();
I guess the code couldn't be easier. Basically what's happening is, when I click my 'save' button, there's a postback and the text in the RadTextBox just disappears.
update Found the problem. My web.config file had a different version of the Telerik dll file that was actually in my bin folder.

I have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
Now user wants that if the text box is clear, the GridView disappear.
I can only find TextBox1_OnTextChanged. But I want to have that while the user is clearing the text, if the length of text becomes zero, the GridView is clear out. So I am looking for OnTextChanging(). Well of course this function does not exist. How to achieve the same purpose?
When changing the textbox's text mode to multiline the textbox becomes resizable during runtime. I can't seem to find the property to disable this, does anyone know how I can resolve this issue?
