Web Forms :: How To Validate Page Controls On Button Click From User Control
Nov 16, 2010
I have little strange question. I would like to Validate my Page Controls on the button click which is there in the User Control. This user control is placed on the Page. If I check Page.IsValid property on button click event, it returns false. But Validation Summary message doesn't popup. So user doesn't know what's happening. It will not save the information and it won't give the validation message too.
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
I am using Linkbutton inside the Repeater Control to display the paging ........and m calling Page change event on client click ....m attaching u code that m using it work fine in some webform but somewhere it didn't go the page change method¬† on clicking page no. .....
I have written a user control that captures some user input and has a Save button to save it to the DB. I use a repeater to render a number of these controls on the page - imagine a list of multiple choice questions with a Save button by each question.
I am loading the user control inside the repeater's ItemDataBound event like this (code simplified):
The problem is that when the Save button is clicked, the page posts back, but lbnUpdate_Click is not called. The Page_Load event of the page itself is called however.
I should mention that the repeater is part of a user control, and that user control is loaded inside another user control (this is a DotNetNuke site which makes heavy use of user controls). The Save button link looks like this:
I have a user control that displays some database records when I first hit the page. When I click the submit button the page load event fires again, loading the user control again. Then the button click event fires inserting a new row in the database which is not shown on the page because the user control already did its stuff. If I could get the user control to do its stuff after the button click event I could then see the newly inserted row. I can do this by pulling the code out of the button click event and sticking it in the page load event. However, I think that would be bad code flow. How can I get the user control to do its stuff after the button click event has fired?
I need to be able to validate multiple validation groups with the click of one button. My Form consists of two text boxes and a drop down list for input. The form also, currently, has three buttons, one for each control. Each of those buttons are tied to a validation control and if the validation is successful, it will add the user inputted data into a database that I have. The interesting part comes when I need to add a forth button which will act as a "Save All" Button. When this button is clicked, I need it to fire the three validation groups.
Is it possible to add multiple validation groups to the "Save All" Button?
I have a User Control that has been added to the page dynamically. When I click a button on that user control:
The button_click event is NOT being raised The page posts back The user control is removed from the page
Here's the button-click event on my User Control:
Protected Sub btnAddAttribute_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddAttribute.Click Try Dim attrName As String = txtAddAttributeName.Text Dim attrValue As String = txtAddAttributeValue.Text 'ADD ATTRIBUTE TO ATTRIBUTE TABLE putSQLData("INSERT INTO OD_Attribute_Values (AttributeName, AttributeValue) VALUES('" & attrValue & "', '" & attrName & "'")...........
I have a blank user control (child) and during Page_Load i create some text boxes and a button. I also add an event to the button.
I then load that user control dynamically from a placeholder in another usercontrol (parent). Both controls are rendered correctly but when i click on the button, the event isnt fired. how to handle the event?
If i use the child control directy (ie without the parent the control) the click event is raised and handled nicely. But when i use the parent control, the debugger wont even hit a breakpoint inside UpdateButton_Click().
I have made a web page in which there is login screen when user login it goes next page but my problem is if i directly enter the url of that page it open. I want it should not open unless the user log in...¬†
I am having a gridview with some button column. I have written some functionality in code behind for the button click. How can i display a confirm dialog in mid of the button click functionality and based on users response(Yes or No from dialog) i need to continue the remaining funtionality in the button click event.
