I am trying to attach a server-side event to lookup the city/state for the user-entered zipcode in a field like the one below.
<asp:TextBox ID="TextZipcode" runat="server" CssClass="inputtext" Columns="10" MaxLength="10"></asp:TextBox>
Since there is no lost focus event to capture, has anyone had any luck getting this to work?
I apologise for the newbie question, but if i have a (e.g) textboxKeyword and i type in "Pets" into the box and instead of having to use my mouse and click on my 'Go' button, I simply hit the 'enter' button and the event gets fired and my datagrid gets filled with all my search criteria. What's the event / code that I would use on the 'textboxKeyword' ?

View 1 RepliesI 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 have a scenario where i have 4 asp buttons , on click of each button there are 4 labels inside 4 seperate divs where each displays seperate data.
Now if i click second button i need to display second label text inside 2nd div and hide all other divs.How can i achieve this ?
OnClientClick event of each button calls displayAlternate() which displays repective div and hides other.
displayAlternate('second'); return false; --> if i do this server side event is not fired ...
If I return true div second label is not getting displayed..
How can I achieve functionality where all divs expect 2nd is hidden and i get server side event also..

<head runat="server">
<title></title>

So I am not able to selected the item properly using list search extender control. Can you please suggest me how can I stop the selectedIndexChanged event.

When I work with the tab Ajax control, and in one tab, I have a Repeater: <asp:Repeater runat="server" ID="rp1" onitemcommand="rp1_ItemCommand"> and in protected void rp1_ItemCommand(object source, RepeaterCommandEventArgs e) method, I add a button and it's event:
Button btn = new Button();
btn.Text = "Update";
btn.Click += new EventHandler(btn_Click);
((Repeater)source).Items[0].Controls.Add(btn);
void btn_Click(object sender, EventArgs e)
{
Response.Redirect("http://google.com");
}
However, when I click on the update button, the event is not raised.
i have created a custom event and assigned a handler to it .
the line which raises event is called one time but handler is getting called TWO times , why it is so ?

I need to load a web user control dynamically.
Looking at [URL] it states that the page lifecycle events are not fired.
I thought I might be able to raise the events through reflection. I cannot figure how to fire the events, am I missing something?
i'm trying to learn about user controls. I created a user control that has a textbox and a button. What i'd like to be able to do is when i click the button in the user control, populate a label in the aspx page. I understand that i could just have a button on the page that uses some properties on the user control to get that information.. but i'd like to know how to do it with the button the user control.. the reason for this is the button is just an example.. a learning tool. if i can get this working, i'd likely be putting thing in the user control that might require this kind of passing information. Anyway.. i've found some c# examples that i tried to get working as vb.. but once started getting into the delegates and events.. well.. it made me turn to this post.
