Forms Data Controls :: GridView Dynamic Footer LinkButton Event Not Fired On Last Page?

Oct 28, 2010

So I have a GridView control with autogenerated column set to true, it also has autogenerated Edit and Delete buttons, sorting and paging, and also I am binding this same gridview to multiple data sources at runtime. All is working well.

Now I am adding a dynamically generated footer row at runtime. This footer row will allow users to add new record regardless which data source it binds to. So it is working as well except there's a small bug I couldn't figure out why. It's when I navigate to the last page of the gridview, if the rows on the last page is less than the page size, for example, I have page size 10 and the rows in last page is 9, then when I click the 'Add' linkbutton, the Add event does not fire, instead, it fill the last page with additional blank rows, that means if the last page has 5 rows, it will fill 5 blank rows below, if it has 9 rows, it will fill 1 blank row below. Then if you click the add again, it will work. If the last page already has 10 rows then, it works just fine.

Below is the code I used to dynamically add footer row:

Forms Data Controls :: LinkButton (ADD) In Footer Not Working In GridView?

Jul 29, 2010

I utilized the "Enhancing the GridView (Inserting a New Record from the GridViewís Footer)" tutorial as an example to add a new record to the Access Database through the footer. Put a break at the RowCommand, but that never happens and the data that I put into the cells in the footer just sit there when I click the ADD link. I have included the portion of the code in CourseBuildDetail.apsx that deals with the TAB that contains the GridView, along with ObjectDataSource and the code that should be triggered when the Add link is click - CourseBuildDetail.apsx.cs. So - what am I missing - example works great.

Forms Data Controls :: Gridview / Adding CheckBox In RowDataBound - CheckedChanged Event Not Fired - Page Lifecycle

Jan 5, 2011

I have a page on which everything is loaded dynamically.

There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event.
The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:

protected void Page_Load(object sender, EventArgs e) {
LoadGrid();
}

But this is very expensive and causes that the db request will be executed twice. If I changed the code to what I want:

protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack)
loadGrid();
}

I get no CheckedChanged event.

Is there a possibility to get:

- Adding a Checkbox in RowDataBound
- Only "LoadGrid()" if it is no PostBack
- Getting the CheckedChanged event of the relevant row

Forms Data Controls :: Dynamic LinkButton Click Event Won't Fire?

Dec 21, 2010

I am working on an ASP.NET web application using .net 4.0 and VS2010.

I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.

The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.

The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.

If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.

I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.

Here is my code: (I removed creating the Textboxes because that is not part of the problem.

Forms Data Controls :: Show Dynamic Sum In GridView Footer?

Jun 9, 2010

I wanted to create CrossTab o/p as In Ms Access. tried couple of articles based upon coding in C# but in one way or other they could not give me final result. Then I posted here.

muhammedsalimp almost resolved my query. But only problem I am left with is adding a TotalSum to the selective columns in GridView or In SQL.

It can be seen from the screen-shot that columns 1-7 does not require sum but columns after 7 all will require sum as they are the Items passed their now will vary from day to day.

Forms Data Controls :: GridView's RowDataBound Event Fired Twice?

Apr 20, 2010

I have a very simple asp.net page, just some buttons and one GridView on it. The logic is a user click the QUery button,then the button click event was trigured to populate the gridview with data queried from database via LINQ. for a user friendly interface, in RowDataBound event, I visit every row, change a boolean value into checkbox represention. But it seem that the RowDataBound run twice, because the checkboxs were inserted twice for every row in one cell. so why? the source code snippet as follow:

protected void btnSelect_Click(object sender, EventArgs e)
{
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
GridView1.DataSource = db.ENTUserAccountSelectAll();//userAccounts;
GridView1.DataBind();
}
protected void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((ENTUserAccount)e.Row.DataItem).IsActive;
chkActive.Enabled = false;
e.Row.Cells[5].Controls.Add(chkActive);
}

Forms Data Controls :: Why Wasn't GridView's RowDataBound Event Fired

Apr 21, 2010

Why wasn't my GridView's RowDataBound event fired? I have a masterpage on whick i have a query button, and I have a content page on which i have a customized GridView(named cgvEmployees,derived from GridView). The logic is when user click the button, the button click event triggered that search the underlying database and populate the GridView.

Everything runs great except that RowDataBound event isn't triggered. Because I have to change some cells' representations in RowDataBound event handler. I have surfed so much pages to find the answer but failed. Below is what i have already done:

1. set the autoeventwireup to true;
2. i have a cgvEmployees.bind() sentence in the button click event handler;
3. i have OnRowDataBound="cgvEmployees_OnRowDataBound" in the content page GridView tag attribute

by the way, the database query is coded by Linq Dynamic Query (please google 'dynamic Linq').

void Master_QueryButton_Click(object sender, EventArgs e)
{
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
NameValueCollection nvcQueryKeyValue = getNVCQueryKeyValue();
Expression<Func<RetiredEmployee, bool>> searchPredicate = getLambdaExpr(nvcQueryKeyValue);
IQueryable<RetiredEmployee> retireds = db.RetiredEmployees;
Expression expr = Expression.Call(typeof(Queryable), "Where",
new Type[] { typeof(RetiredEmployee) }, Expression.Constant(retireds), searchPredicate);
IQueryable<RetiredEmployee> query = db.RetiredEmployees.AsQueryable().Provider.CreateQuery<RetiredEmployee>(expr);
List<RetiredEmployee> employeeList = new List<RetiredEmployee>(query);
List<RetiredEmployeeEO> employees = new List<RetiredEmployeeEO>();
foreach (RetiredEmployee employee in employeeList)
{
RetiredEmployeeEO employeeEO = new RetiredEmployeeEO();
employeeEO.MapEntityToProperties(employee);
employees.Add(employeeEO);
}
cgvEmployees1.ListClassName = typeof(RetiredEmployeeEOList).AssemblyQualifiedName;
cgvEmployees1.LoadMethodName = "LoadFromQuery";
cgvEmployees1.LoadMethodParameters.Clear();
cgvEmployees1.LoadMethodParameters.Add(employees);
cgvEmployees1.DataBind();
}
protected void cgvEmployees1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//Add the edit link to the action column.
HyperLink editLink = new HyperLink();
if (((BasePage)this.Page).ReadOnly)
{
editLink.Text = "View";
}
else
{
editLink.Text = "Edit";
}
editLink.NavigateUrl = "employee.aspx" + EncryptQueryString("id=" + ((RetiredEmployeeEO)e.Row.DataItem).ID.ToString());
if(e.Row.Cells[0].Controls.Count==0)
e.Row.Cells[0].Controls.Add(editLink);
//Add checkbox to display the isactive field.
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((RetiredEmployeeEO)e.Row.DataItem).liveOrDead;
chkActive.Enabled = false;
if(e.Row.Cells[24].Controls.Count==0)
e.Row.Cells[24].Controls.Add(chkActive);
if (((RetiredEmployeeEO)e.Row.DataItem).gender.Equals((byte)1))
e.Row.Cells[2].Text = "Male";

Forms Data Controls :: How To Find The Row Of A Gridview Which Contains A Control That Fired An Event

Dec 20, 2010

I have a Gridview which contains templated column that has 5 checkboxes in it. When you click on one checkbox, I want to uncheck the other 4.

I am using the Item Template for this. I don't want the user to have to Select a row, before clicking on the checkboxes. Here is my non-working code to uncheck the other checkboxes. I realize it's not "SelectedRow" that I want since there's no selected row, so how do I find the row containing the checkbox that fired off CheckChanged?

Forms Data Controls :: The Gridview Fired Event RowEditing Which Wasn't Handled

Aug 5, 2010

I've got a gridview that returns student order history which works just fine. It pulls the StudentId from a hidden field on page load. I have a link button that ADDS AN ORDER when clicked. It calls a stored procedure, inserts the record, then rebinds the gridview and displays the new record at the top of the list.

Problem is when I go to EDIT it, i get this error... "The GridView 'GridViewOrderHistory' fired event RowEditing which wasn't handled." But the interesting thing is the error doesn't occur if I close the browser and reload the page and then click on that new record that was created. Obviously I'm missing something in my code when the new order is created. Here are the 2 subs involved in the process.

Forms Data Controls :: Event Of Child GridView Is Getting Fired Also At The Parent FormView?

Jul 21, 2010

since APS.Net 4.0 I have a curious problem with an event.

There is a FormView and inside of the EditItem there is a GridView. In the Footer of the GridView I put Controls for inserting records.

But when I fire a markup defined RowCommand of that GridView then the same event is getting fired for the Parent FormView. First I had 'Insert' as the CommandName and so I was getting the Error that my FormView had to be in insert mode to insert a record. Then I changed the RowCommand of the GridView to 'xxx' and I got also the RowCommand 'xxx' at the RowCommand eventhandler of the Parent FormView.

The project was migrated from .Net 3.5 a few days ago, but nothing was manually changed in the code/markup. And the problem was not there with the "old" framework.

[Code]....

Of course, I could simply change the CommanName of the LinkButton e.g. to 'InsertChild' but I would like to know:

Is this a known change or a bug of ASP.Net 4.0?

Forms Data Controls :: Gridview Dynamic LinkButton Control With CommandName ?

Jun 13, 2010

the structure is like this:

ItemTemplate
PlaceHolder

And then I try to add some dynamic controls into the placehold control from code behind, I use the RowDataBound Event

Private Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
Dim ph As PlaceHolder = CType(e.Row.Cells(1).FindControl("PlaceHolder"), PlaceHolder)[code]....

The problem is the button CommandName is not functioning. And more strangely, if I add the button manually into the placeholder, like this:

Web Forms :: Dynamic Button Event Created Within Class Library Not Fired?

Jul 30, 2010

I know this 'dyanamic control event not fired' has been raised time and time again, but I still can't work out how to solve this issue...

I'll break down the parts and where the button is created without the 'flesh' around the code that shouldn't have an effect.

Imagine this is the stack:

[Code]....

button_Click never gets fired. The annoying thing is in the app, if button list isn't used, RadioButtonList is and is attached in exactly the same way and while i haven't checked, i'd imagine I would be able to catch events from that.
