my proplem when i check checkbox this event checkBox_CheckedChanged its fired but when i uncheck checkbox its not fired.
i am trying to do is set my page up so that when a user clicks on a row in the gridview a hidden checkbox is unchecked... i am new to asp.net but never thought something as simple like this could be so difficult to work out... i've been on it for around 5 weeks now, i started this on my first day of the website, and have actually designed and written the entire site while still trying to work this out... i first did this on the selectedindexchanged event:
Dim cbox As CheckBox = CType(GridView1.Rows(GridView1.SelectedIndex).FindControl("CheckBox1"), CheckBox)
If cbox IsNot Nothing Then
If cbox.Checked = True Then[code]....
problem is the above code throws up errors...! once i take out the where clause it unchecks every checkbox and writes it back... is there a way i can say just uncheck the selectedrow checkbox and update that one row???
i'll admit there are better ways of doing this, and i'm sure the above code is a little messy,
when i checked the checkbox in parent gridview, all checkbox in child gridview will be checked.
how can i select the checkbox of child gridview checkbox in the when i select the checkbox from the parent gridview?
code behind
protected void OnCheckedChanged(object sender, EventArgs e)
{

i made a checkbox templatefield in gridview that let me select the rows wanted ...and i have a button to do something for all rows selected ...my problem is after click button i want unchech all checkbox in gridview ...i wrote this code but not working:

//TextBox1.Text = "";
foreach (GridViewRow gvr in gdfacture.Rows) {
if (gvr.RowType == DataControlRowType.DataRow) {
CheckBox cb = (CheckBox)(gvr.FindControl("chkSelect"));

i have a gridview with templatefield in templatefield there is a checkbox and in there are textboxes.
i want when i check the checkbox then only that row can active and the textboxes are enabled true when deselect the checkbox then that row should enable false.
I am using a GridView Control to display multiple fileds with 0's and 1's.
I am using template fields where CheckBoxes are used.
Where exactly and how do I apply the Logic to get a checked CheckBox when field Value=1 and unchecked CheckBox when field Value=2 .Also some times to be able to write a YES where fieldValue=1 or NO where filedValue=0
Do I apply this logic using asp or C#? How?

View 2 RepliesI have a checkbox inside the item template of a datalist, dtlLate. I want to detect the checkbox change and execute a stored procedure. When I click the checkbox a postback does occur but the dtl Late itemcommand doesn't fire. I am not rebinding the datalist on postback. I have tried with viewstate enabled and disabled. I have used Bold text for the dtlLate in the content page and in the codebehind to make it easy to find.

Is there a way of setting the default unchecked value of a checkbox? Am not using a databound control. This is passing data from a form and would like it to pass false as opposed to null when unchecked.
View 2 RepliesI've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event..
[Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.
how to make a checkbox is always unchecked even after form submit where a user tick the checkbox. The checkbox is for acknowledgment that user agrees to the terms and conditions ... and when form submit return some errors I want to display the error message on the screen and keep the checkbox unchecked regardless it was ticked or not.
In my view I have the following:
<%: Html.CheckBoxFor(m => m.UserAgreement) %>
And I have tried both the following in my controller and none of them works:
ViewData["UserAgreement"] = false;
return View(new MyModel { UserAgreement = false});
[code]....
It works on Internet Explorer but I have few users who started to use apple's snow leopard and event is not at all firing on those browsers.
I believe some browsers have different JavaScript implementation
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
View 3 RepliesI am working on a datagrid that has a column with checkboxes... the checkboxes should be checked when the page loaded. The problem is that whenever I trigger a postback, all the checkboxes will be unchecked!!
I don't know what is causing this or what should I do to prevent it from unchecking the checkboxes.
I tried some of the example from the web, but all of them will check/uncheck all the checkboxes in the form, NOT only in the repeater. Is there a way to implement this and only apply to repeater.
View 5 RepliesI have a div in which i have few text boxes and checkboxes, i wrote checkboxchanged event but it is not firing when i check or uncheck the checkbox i set the autopostback property of the checkbox = true but still no result. does any one have idea how to control this scenario.

when i click chk_packages checkbox myCheckedChanged fired and i want single checkbox to get enable
I am displaying my table data using listview control. It is working fine.
Now I would like to add a checkbox in front of every item so then when user checks the checkbox and click on delete button inside or outside the listview control then i want all the records to be deleted.
I am creating an array of checkboxes :
1. chkresponse = new System.Web.UI.WebControls.CheckBox[cnumber + 1];
for (int
i = 0; i < cnumber + 1; i++){
chkresponse[i] = new System.Web.UI.WebControls.CheckBox();
chkresponse[i].CheckedChanged +=
new EventHandler(chkresponse_CheckedChanged);
chkresponse[i].AutoPostBack =true;
}
2. thereafter adding them to a panel
Panel1.Controls.Add(chkresponse[n]);
3. then added the checkedchanged event:
public
void chkresponse_CheckedChanged(Object sender, System.EventArgs e)
{Label1.Text = "response";}
but the event is never fired. the panel is insdie an updatepanel.
I am using a datalist with checkbox and datalist is in a panel. I am poping the panel by using ajax modal pop-up. When we check the checkbox the checkedchange event is firing. But, when we uncheck the checkbox the event is not firing. It is user control and it is in update panel.
View 1 RepliesI have a checkbox, textbox and requiredfieldvalidator inside the updatepanel. Once user checks selects
checkbox I am enabling requiredfieldvalidator.
I have one more textbox, requiredfieldvalidator, validationgroup and Linkbutton outside updatepanel.
Strange thing is Checkbox checked event not firing in some cases,
1. Check the checkbox (which enables requiredfieldvalidator)
2. Click the Linkbutton (fires two validators)
3. Uncheck the checkbox (which should disable requiredfieldvalidator)
4. Click the linkbutton again (again it fires two validator, which should fire only one validator)
Note: The problem only arising when I add javascript block to linkbutton in page load event.
