Web Forms :: How To Get Click Event To Work With Checkbox
Aug 26, 2010
I have a webform with 2 listboxes and 2 checkboxes... When I check checkbox1 I want listbox1 to be disabled and checkbox2 to be disabled. Similarly, when I check checkbox2 I want listbox2 to be disabled and checkbox1 to be disabled. The code does not show any errors; however, when I run the Page everything appears as it is supposed to but when I check the boxes, nothing happens. What am I missing that will link the code on the .aspx.vb page to the objects on the .aspx page and make them work together?
my page are 1 checkbox and 1 hidden label and 1 hidden panel. With the help of forum member raghav_khunger I've managed to write the code which shows panel and label when checkBox is checked. I've also added the code which is checking on every page post back the status of checkbox and hide/show panel and label appropriately. This is working fine.However when I add jQuery Safari checkbox plugin [URL] problems appear.
Looks like the code which is handling click event is doing reverse thing: when panel and label should be hidden are shown. I can change this but then there would be problems because of the second part of the code which is checking checkbox on page load. So when I check the checkbox nothing happens. I must uncheck it and label and panel appears. But if panel is uncheck the label and panel would be hidden because on next page load (when user clicks button next).As I said before the same code is working fine and it's test in all browsers (IE,FF,O,S,C). Maybe there is problem with checkbox plugin since it's in beta version.
i have datalist and on button click event i check the checkbox is checked or notfor this my code is
<asp:DataList runat="server" ID="dlstproductsize"> <ItemTemplate> <input type="checkbox" value="<%#eval("size_id")%>" id="chksize" runat="server" /> <%#Eval("name")%> </ItemTemplate> </asp:DataList> If chkallowsize.Checked = True Then For Each item In dlstproductsize.Items If (CType(item.FindControl("chksize"), HtmlInputCheckBox)).Checked = True Then ocommon.ProductMapingInsert(uniq_id.Text, CType(item.FindControl("chksize"), HtmlInputCheckBox).Value) End If Next End If
i get the error like object reference not set to the object
I try to create a asp.net 4 webpage, using masterpage.
On webpage I have a formview and inside the formview I have a ajax modalpopup. I have multiple buttons and textboxes on the modalpopup, and created a test event, but I still get the message that the textbox is not declared.
I want to select all checkBox in Gridview when click to header checkBox.I have created design such that CheckBox is not available to header of Gridview.It is in other table. Below is design of gridview.
I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)
I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this.
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.
I've been searching a little bit to try and find the answer to this problem. As of right now another person I work with has designed a wizard step with an upload button in part of it. After the person clicks the browse button and selects their file a validation statement comes up saying, "Please click 'upload and continue' or clear the field" and then is supposed to disable the continue button until this is done. He started by adding a RegularExpressionValidator and found it did not solve his problem.
Now that he's out today we're working on trying to solve this and my first though is to actually use a custom validator instead and have it call a function in the back-code for validation which checks to see if the "Upload" click-event has happened. Is there an easy way of verifying whether or not a click-event has occurred. Basically my conditional is shown in the pseudo-code below...
i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).
i have an form with an button and some input controls. some time due to input problem i may get error after that if i refreshed the page then that time the button click event has fired, how to avoid this kind of bad event fire.
I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
I am updateing my gridview using button click event but at the fisrt time it does not get updated first time but its works second time i dont know why . Dol u know how to genterate two button click event for the same button.Records never get updated on first button click event but its works on second button click event.
I have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.
This event handler is not responding at all to the click event. On click, the pagination numbers disappear and I'm not able to trace it in the debugger because the event handle doesn't even fire so I have no idea what's going on.
