I have a BING MAP in web app. which is of JavaScript or Jquery. And also I have a DataGrid in same page. Data Grid is populated with Address ROWS. A check box is also there as ItemTemplate for DataGrid.
Now after dataGrid binded with data source, and when user clicks on check box, that particular address should show on BING MAP.
My question is,
How to invoke a JavaScript function when user checks checkbox in data grid. Which data Grid events suits my scenario? Also can I do this on client side without going to server side and call JS function?
I have a project in VB.NET which is working fine which essentially has a Datagrid that has a TemplateColumn included which is a column of Checkboxes. The code to declare the datagrid is here...
as you can see the Checkbox has Autopostback="true" but there are other things on the page which produce postbacks as well.
My Page_load has this in it, being called on every load of the page, postbacks included...
Dim strGUID As String strGUID = Session("strGUID") dgDates.DataSource = SqlHelper.ExecuteDataset(ConfigurationManager.AppSettings(Web. [Global].CfgKeyConnStringADMIN), "dbo.spRptGetSchedulingDates", strGUID) dgDates.DataBind() intNumberOfDates = dgDates.Items().Count
as well my code behind has the following code for the gridItemDataBound
Protected Sub gridItemDataBound(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) 'hide the intRptSchedulingDatesID for each row in the checkbox's content style variable If (e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem) Then CType(e.Item.FindControl("cbStaticRolling"), CheckBox).Style("Content") = CType(e.Item.DataItem, System.Data.DataRowView).Item("intRptSchedulingDatesID") End If End Sub
everything you see sbove is working perfectly fine...in the sense that when I click one of the checkboxes, the page_load fires, the gridItemDataBound fires on DataBind() and when all is done, the checkbox retains the value that the user clicked the checkbox.
With all this exact same code converted to C#....the events all fire in the same order, but the checkbox selected value always clears...any thoughts??
I was trying to find out if there are any check boxes checked in the datagrid, if non of them is checked it should show me an alert to select atleast one.
My problem starts when there is paging in datagrid...
not able to check the entire datagrid at a time in itemDataBound event for the checked check boxes.
This morning I posted a question w.r.t Radio Buttons, but the requirement changed so I'm posing a similar question.
I want to have a checkbox in a datagrid.
Suppose I click on one of the checkboxes and then realize i need to click on another, the screen has to automatically uncheck the previously clicked checkbox and then check the newly clicked checkbox.
In other words I need to clear previously checked checkboxes and check the recently clicked checkbox.
Also, I need to update a label in the page with a value associated with the row of the checked checkbox.
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
I have a 45 checkboxes in webform with values 1 to 45 i want ...to insert checkbox checked value to textbox in comma seperated string as in ascending order as 1,2,3,4,5 ...if checkbox1, checkbox2, checkbox3, checkbox4 and checkbox5 is checked...if these checkboxes will be unchecked then the inserted value in textbox will be removed 1 by one respectively. ..
hwo to do this using vb.net or jquery or javascript ..
I have a checkbox on my project and I have textboxes as well. I tried some jquery code as you can see below for this function;
I would like to get the ctl00$MainContent$firstnametxt.text value to ctl00$MainContent$firstnamedrivertxt.text value when the checkbox is clicked and I want the ctl00$MainContent$firstnamedrivertxt.text to be null if the checkbox is unchecked. how can I do that? the below one doesn't work for me.
If view_test button was clicked, initializing the dialog, before the form post backs the checkbox ch1.Checked property in .Net is always False. However if you just postback without initializing the dialog it works as expected.
I have a gridview with 5 columns , i am bind gridview on pageload .... each row of gridview has a checkbox aslo ..... and i have a hyperlink outside the gridview..
I want that when i check checkbox of particular row the 'Firstname' field of that row should display as link , i am using jquery to avoid postback .. but not able to get that field value as link.
I have a grid view with two columns A and B. Column A has Checkboxes and Column B has numeric values(int). When user checked checkboxes the checked checkboxes column B have to added and displayed in a Label.
I have an html checkbox that controls a list of checkboxes. I want this checkbox to display in a sorta "null" state where it is neither true nor false. <HeaderTemplate> <div style="width:90px"> Toggle: <input id="chkAll" onclick="javascript:SelectAllCheckboxes(this);" runat="server" type="checkbox" /> </div> </HeaderTemplate>
- How can I uncheck a checkbox using client side code when the other checkbox is checked? - Is there a way to check server side on form submission that at least one check box is checked?
I have a Datagrid with 2 textbox template columnsand two checkbox template columns. I have two other Textbox controls and two CheckBox controls. I have an Add button.
I want to be able to use the add button to update Datagrid Record inserting the Textbox control texts and the Checkbox Control status.
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 a report page, that displays many rows, each row having its own checkbox with its value being an ID field from the database.This is for a bulk operation, that will be preformed on all the row's where the checkbox was checked.So if the user checks multiple boxes, hits a button, I need to send all the checkbox values to a controller's action that will take those Id's and process them.
Using Asp.net Webforms how can I validate that a checkbox has been checked. (I cannot do a postback) has to be in javascript (either custom - working with the existing validation controls for other fields. or using a .net validation control)
I have a gridview with one column of checkboxes and other columns with different custom controls. What I want is that when a checkbox is checked an event is triggered which toggles the visibility of other elements in the row .
what is the code to retrieve the id associates with each checkbox and read if whether each checkbox is checked or not in the controller action(I will need to get the status in both conditions, checked or unchecked )?
