View 27 RepliesI have 3 textbox with 3 asp.net validators targeting each textBox in a Web Form.
textBox1RequiredValidator1
textBox2
RequiredValidator2
textBox3
RegularExpressionValidator1
Can i fire RequiredValidator1 only When i Move the focus out of TextBox1 ?The Same thing has to happen for all the other TextBoxes and fire their corresponding validators.
have a CustomValidator in a user control which validates text in TextBox ( TextBox is in user control ). I am using this user control in multiple pages. For some pages i need fire custom Validator and for some pages not.

I have two custom validators that are in the same validation group. This validation group is launched by one button. My question is, in what order will the custom validators fire in? It appears that the validator that is placed earlier in the aspx page fires first, but I don't want to rely solely on this.
View 2 RepliesI've a Detailsview that contains an updatepanel.A button is pressed within the panel and a window is displayed containing a gridview list.The user selects an item from the list, the window closes and the selected gridview item is placed in "tbResourceID" My problem however comes when the user goes to click insert the validator doesn't fire. I'm guessing this is something to do with the updatepanel isolating the validator.... my code is shown below!

I have a button which has a click event but its not firing on the first click. I suspect its something to do with that i am in dropdown box control so when i click the Button the event for the dropdown box occurs (textChanged) but it forgets about the click event
Of course if i click it a second time it works.
Or if i click somewhere else first so that the event TextChange occurs and then click the Button the first time it executes..
Is this normal and what are more workarounds if any?
basically the TextChange event must fire but the button click event must fire as well.
All the events i am talking about are ASP.NET events.
here is some examples of the events i am using - both the button and dropdown
uxGetData is a button and uxToDate is a dropdown box

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..
Below is code.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>

fire event in webform?
[Code]....
lets say I have a control with a button in it. I want to use my control on a page but then know when the button in the control has been clicked. I assume I need to fire some sort of event when the user clicks the button and then in my parent page I can hook into onMyCustomEvent or something..
How do I do this?
Example I have unsubscribed (is want to clear off the previous subscribed event) and subscribed the events every time when dataobject value has assigned:
_dataobject.OnQueryOpen -= new DataObject.On_QueryOpen(RefreshIGrid);
_dataobject.OnQueryOpen += new DataObject.On_QueryOpen(RefreshIGrid);
But, the RefreshIGrid still fired depend on how many times my dataobject has been assigned.
is it not really unsubscribed on what I have -= from the begining?

I added dropdownlist & textbox control to gridviewrow dynamically on button click.I bind datatable to dropdownlist programatically & dropdownlist Datatextfield="product" & Datavaluefield="Amount". now my question is: when I select a product in dropdownlist,the corresponding product item "Amount" should display in the textbox. I write in my dropdown event like this:
protected void ddl1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow gridViewRow = (GridViewRow)(((Control)sender).NamingContainer);
DropDownList ddl1 = (DropDownList)gridViewRow.FindControl("ddl1");
TextBox itProductQuantity = (TextBox)gridViewRow.FindControl("itProductQuantity");
itProductQuantity.Text = ((DropDownList)sender).SelectedValue;
}
I call that textbox in Gridview row databound. why event is not firing?
