protected void rbOpgelost_CheckedChanged(object sender, EventArgs e)
{
tbEinddatum.Text = DateTime.Now.ToString();
}

Forms Data Controls :: Setting Focus On A Textbox In A Row When Clicking "Edit" Button?

AJAX :: Change Textbox Backcolor In An Updatepanel On Button Click?

Mar 22, 2010

I'm using a searchoption on my website. (language = VB)

The user can choose a searchcriteria out of a dropdownlist (Artist name, Description, Price, Genre, Type) . If the user selects one of the options in the dropdownlist the correct textboxes are shown.

For example: if the user selects Price he gets two textboxes (one for the min price and one for the max price) if the user selects Artist Name he gets one textbox

The dropdownlist and the textboxes are put into an updatepanel. The searchbutton is outside the updatepanel.

Now for the problem:

If the user doesn't fill in a textbox and presses the searchbutton, the backcolor of that empty textbox should be turned red. The searchbutton is set as a trigger and the panel is updated on the buttonclick, but the colors don't show.

In the clickevent of the button I've said the following code:

If txtCriteria.text = "" then
txtCriteria.backcolor = Red
Else
txtCriteria.backcolor = White
End if

Quite a simple piece of code. This works if I remove the updatepanel from my page, but I'd like to keep the updatepanel because it's really nice :p.

Button Re-appear Immediately After Clicking Button In ListView Row?

Mar 12, 2010

I have 4 buttons on a page. Each button opens a modal window and let's the user input data in a form. When the user hits the save button in the modal, a ListView appears on the page with the submitted data.

The button the user clicked to open the modal window is set to visible=false, so it's gone when the row is added to the ListView. Now there are 3 buttons and the same goes for those; when the user hits a button, a modal appears, and when the modal form is submitted, the button disappears and a row is added to the ListView.

In the ListView row, there is a delete button. When this button is clicked, the row is deleted and the button that was initially clicked to add this row (and open the modal), SHOULD reappear, but it doesn't. The row disappears, but I have to refresh the page before the button comes back. There is a ScriptManager on the masterpage, so I guess this is an AJAX partial refresh issue. I tried adding different events, but I can't find the one that fires at the right time.

I use an ObjectDataSource to fill the ListView, and the data comes from a database, wrapped in a business object.This code loads a business object in a List<> and checks if the user inserted an item of a specific type. If he did, the button he used to open the modal is hidden. This works fine (maybe not the most elegant)

_goals = GoalManager.GetGoalsByUser(UserID);

if (_goals != null)
{
foreach (Goal _goalinlist in _goals) [code]...

As you can see, I tried setting a boolean, and then check it when the page is re-loaded. But the problem (I guess) is that the whole page isn't refreshed when the delete button is clicked in the ListView.

This is the delete button in the ListView:

<asp:ImageButton ID="ImageButton2" runat="server" CommandName="Delete" CausesValidation="false"
ToolTip="Delete" CommandArgument='<%#Eval("GoalID")%>' ImageUrl="delete.gif"
OnClientClick="return confirm('Delete this post?');" CssClass="button"/>

I guess the question is, how do I make the button re-appear right after the ListView button is clicked?

Web Forms :: Shows Two Button Instead Of One When Clicking On Button

Aug 17, 2010

I have this issue i have been looking at for a while and cant seem to figure it out. I have two ddl's on my page and a InsertCommand from sqldatasource. My InsertCommand is actually updating the foreign key of the two ddl's in another table. When i click on my button it shows two numbers instead of one. The challenging thing now is that i have

DDLName.Items.RemoveAT("itemName.SelectedIndex")

after the insert so it would not duplicate what i am updating. If i take this statement out of my code. it updates well as in showing the one record that was updated. if i put it back in there it shows two records where updated. I tested my sql statement and its working fine meaning it shows only one record is updating.

C# - Displaying Sourcecode When Clicking A Button?

Jan 17, 2011

With that said I'm looking for a way to load sourcecode from the codebehind file into a textbox, when clicking a button. Same goes for the aspx file.

Im making this website, where i am going to show code examples from what im doing. So if I navigate to myweb.com/tutorial1done.aspx this page would show me the final result from the tutorial done. When i click the show source button it should make 2 textboxes visible, and add the codebehind to the first box, and the aspx source to the second box.

I don't know if it is possible, but I am hoping so.

This far i have this:

ASPX:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="DateTimeOutput.aspx.cs" Inherits="WebApplication1.DateTimeOutput" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
