Forms Data Controls :: DataGrid - Setting Focus After A TextBox TextChanged() Event?
Oct 27, 2010Asp.NET v2.0
Data grid with mulitple texboxes per row.
Each textbox has a TextChange() event wired up for data validation.
These events fire just fine, the data validation works just fine.
My issue is this: User enters text into TextBox1 one then tabs into TextBox2. The cursor appears for a split second inside of TextBox2 then disappears as focus is being set somewhere else on the page. I'm not sure how that change of focus is happening.
In this scenario, after tabbing out of TextBox1, how can I maintain focus on TextBox2 (and then subsequently TextBox3, TextBox4,etc..)
AJAX :: SliderExtender Causes TextChanged Event To Fire On Every PostBack?
Oct 7, 2010I need a Slider that will only postback when the slider has been moved. Can this be achieved with SliderExtender?
I have a TextBox with autopostback=true, within an updatepanel within a usercontrol. The TextBox is extended by SliderExtender (default settings).
The TextBox's TextChanged event fires perfectly when the slider is moved (MouseUp - standard extender setting). The aspx page is partially posted back, and all is well.
However, if another usercontrol on the same aspx page causes a partial postback, the SliderExtender causes the TextChanged event to be raised - for no aparent reason. This is causing problems.
Is it possible to prevent postback unless the slider has actually been moved?!
Forms Data Controls :: Change Formatting Of Text In TextBox Via Server-side TextChanged Event
May 6, 2010I 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" />

Web Forms :: Bypass The Textbox Textchanged Event On The Serverside?
Jan 20, 2010i have a gridview with commandbutton column and a textbox template column. My requirement is changing the text and hitting the enter key should also perform the same function as the command button. So i enabled the autopostback of the textbox.But if i click the command button after changing the text in the text box fires both the TextChanged event as well as the item command event. Is there anyway to bypass the Textbox text change event if i postback using the grid command button?
View 2 RepliesUpdate Panel - Textbox TextChanged Event Is Interfering With The DropDown SelectedIndexChanged Event?
Oct 20, 2010Basics: I have a text box (txtDepositAmount) that people can enter a deposit amount into and a drop down (ddlSelectedTerm) that sets the terms. Through these two values I calculate the APY (lblCurrentApy).
Rules: If only one of the values is selected I still want to do an update on the current APY label and clear it. If either value changes I want to update the current APY and recalculate.
The problem: As soon as I click away from the textbox and onto the drop down to select my term the drop down flashes and closes because the textbox TextChanged event was just fired.
I have to click on the drop down a second time to be able to select anything!
Do I need to change what event I'm looking at or do I need to move some of the controls outside of the UpdatePanel? Can this only happen if some of the business rules change? Should I just give up and go to javascript?

Javascript - .NET TextBox TextChanged Event Not Firing In Custom EditorPart
Jun 4, 2010This is a classic sort of question, I suppose, but it seems that most people are interested in having the textbox cause a postback. I'm not. I just want the event to fire when a postback occurs.
I have created a webpart with a custom editorpart. The editorpart renders with a textbox and a button. Clicking the button causes a dialog to open. When the dialog is closed, it sets the value of the textbox via javascript and then does __doPostBack using the ClientID of the editorpart.
The postback happens, but the TextChanged event never fires, and I'm not sure if it's a problem with the way __doPostBack is invoked, or if it's because of the way I'm setting up the event handler, or something else. Here's what I think is the relevant portion of the code from the editorpart:
protected override void CreateChildControls()
{
_txtListUrl = new TextBox();
_txtListUrl.ID = "targetSPList";[code].....
