C# - OnCheckedChanged Event Fires More And More Times For Every Time It Is Clicked?

Aug 31, 2010

I have an ASP.NET page that contains a gridview.

I have to create columns dynamically based on a datatable, some field type info and some header texts.

I do that by creating templates.

It created the grid fine and all looks good, however when i click a checkbox and the checkedchanged event fires then something odd happens

The first time i click its fine and i get the expected values in the event

But the second time then the event gets fired with the values from the first time and then again with the values from the checkbox that i actually clicked.. The third time the event gets fired 3 times, first 2 times with the old values and the third with the correct value.

Here is the code:

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Text.RegularExpressions;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;........

Web Forms :: Checkbox In Gridview Doesn't Fire OnCheckedChanged Event

Oct 26, 2010

Here is my situation: I have a overview of subscriptions that look simple:

Active (bool), ID (int), StartDate (datetime) and MaxUsers (int).

I've put this in a Gridview and it renders nicely.

Now everything is simply in ItemTemplates and are formatted.

Now a new feature: In the Gridview active should be a checkbox and when clicked on it, it should (de)activate the subscription. Or simply said, Active status is updated. Now me being a simpleton thinks:

[Code]....

and the cs:

[Code]....

But! the event doesnt get fired. Now I've searched with google and also through this forum and every time I get the answer: autopostback on true or use commandname. Now for this little feature I think the commandname use in combi with rowbound is overkill for such a little thing.

Now I hope I'm just missing something because this would be really nasty and stupid to make it so complicated. I like the autopostback and oncheckchanged combination because it logical, but why doesnt it work?

Web Forms :: CheckBox Oncheckedchanged Event Causing Strange Behavior On Postback?

Jun 11, 2010

I have an issue that seems to only happen on my production server. I show or hide table rows whenever the buttons are clicked. However, when I do a postback on the checkbox, all of the rows become visible and the textbox stays empty. It works correctly on my test server and local workstation, just not in production.

Here is the markup...

[Code]....

Here is the code behind...

[Code]....

Here are the unexpected results whenever I check the chkShow2 checkbox... I am guessing this is a configuration issue on the server.

Web Forms :: Why CheckBox Is Not Getting Checked On OnCheckedChanged

May 14, 2010

I have a CheckBox field inside a Formview.

<asp:FormView ID="_fvApplicant" runat="server" DefaultMode="Edit" OnItemDeleting="ApplicantItemDeleting" Width="100%" DataSourceID="_dsApplicant" ondatabound="ApplicantFormBound">
<asp:CheckBox ID="_chkSuitable" OnCheckedChanged="test" AutoPostBack="true" CausesValidation="true" runat="server" Checked='<%# Bind("Suitable") %>' /></td>

In my Code Behind in test method I am trying to set the checked to true, but in the ApplicantFormBound event when i debug it is never true...any reasons why? Basically I want to set the Validator to true when checked.

protected void test(object sender, EventArgs e)
{
CheckBox vld = (CheckBox)_fvApplicant.FindControl("_chkSuitable");
vld.Checked = true;
_fvApplicant.DataBind();
}
protected void ApplicantFormBound(object sender, EventArgs e)
{
var chk = (CheckBox)_fvApplicant.FindControl("_chkSuitable");
if (chk != null)

Forms Data Controls :: Using Datakeys In A Gridview?

Jul 16, 2010

I have a gridview with a linkbutton in each row. When I click the linkbutton it should update the status of a field from enabled to disabled. I am using a stored procedure to achieve this but i need to pass in a ApplicationID which i am retrieving from the gridview through the use of datakeynames. I am using the code below to get this value into a variable.

iAppID = gvApplications.DataKeys(gvApplications.SelectedIndex).Values("iApplicationID")

However when it runs it gives me the following error:

Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

Forms Data Controls :: ListView Paging Dies Using Datakeys?

Mar 19, 2010

I've got a big problem here with the ListView control. Basically I've got very basic code, yet it seems to break the control completely.

Here's the deal, I got a simple ListView using an ItemTemplate containing a hyperlink. Obviously the hyperlink has to lead somewhere after clicking, so the datakeys enter the scene since I need to hook up a hyperlink containing the Id of the record it's in as a parameter.

Normally this shouldn't be a problem, so in the itemcreated event I look up the link control and add the url using data foud in the datakeys.So far so good, this all works out fine.

Now this contains a number of records, too many to display on one page, so I decided to implement paging by using a DataPager, which is the way to get the ListView to support paging. This didn't work.

After a little tinkering around with the code, I found that if I didn't get any datakeys in the itemcreated event, that it all works fine. However, I need to use the datakeys or I won't be able to hook up a url to the hyperlink.

Basically, that one line of code completely kills paging. Commenting it out immediately sets things right, but that's not an option.

Forms Data Controls :: DataKeyNames & DataKeys Not Working On Other Pages?

Feb 21, 2011

When the page is displayed have labels, textboxs, and dropdownlists on top part of the page then the gridview at the bottom with the page numbers at the bottom of the gridview. Create the columns and add data to the gridview programmatically with several hidden columns. Use DataKeyNames on the source page and use DataKeys in VB.Net code behind to get data from the hidden column cells of the selected row. On the
first page when a row is selected, the textboxes and dropdownlists have thecorrect information from the gridview hidden columns. When select another page from pages numbers at the bottom of the gridview and select a row from the new page, get theinformation from the hidden column from the first page andcorrect data from the columns that are displayed onnewly selected page.
