i have a gridview that has the ability to sort by each of the columns, but suppose if i'm on page 2 of the results and sort any of the columns, it jumps back to page 1. is there a way to keep it on page 2, still have the sorted date work?
View 3 RepliesI have a page with a TextBox, a Button, a GridView, and a SqlDataSource. I click the Button to execute the SQL in the TextBox using the SqlDataSource. The SqlDataSource populates the GridView. Everything works as expected until I click a column heading to sort.
When I click a column heading, the GridView disappears and I have to click the Button to display the grid again. When I do, the grid is displayed in the order of the column I clicked.
I don't understand why the GridView is disappearing when I click a column header.
Does anyone know how to fix this so the GridView is sorted and displayed only by clicking the column header?

I have several grid views indide div's, and when I click the Sort header on an open div the div collapses and no sort happens. I believe it is just reloading the entire page but when I surround PageLoad with !ISPostBack then the page redraws as blank. Since the sort script is generated by the GV, I don't know how to stop it from creating side effects.
Here's my code:
<script type="text/javascript" language="javascript">
function toggleDisplay(id) {
var obj = document.getElementById(id);
obj.style.display = (obj.style.display == "none") ? "" : "none";
return false; // cancel the href
}
</script>

I have a page displays CRM data (with CrmService) in GridView. Everything run ok until I tried to sort out one field by default and I received the following exception: The GridView 'GridView1' fired event Sorting which wasn't handled. The reason I am using GridView to do the sorting because:
1) Cannot do it with SQL "ORDER BY" since date retrieval from CRM Web Service
2) Cannot use OrderExpression for QueryExpression from CRM because the column I want to sort is generated by my algorithm
GridView1.Sort("ColumnName" SortDirection.Descending);
in Page_Load, or Button1_Sort(object sender, GridViewSortEventArgs e), they all trigger the above execption!
I also added the method to the following method to handle exception, but didn't work:
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
GridView1.Sort("ColumnName" SortDirection.Descending);
}
I am using gridview created by visual components. I have registered gridview_onsortclick event during the page initialisation, but when i try to click on the header of any column, this event does not get fired at that time. This event gets fired only after all the controls, sorting query is generated, filling the current dataset is done. But the same event is getting fired before query is generated and dataset is filled,for the other page. And one more thing to add with it, I want the sort function to be done on the whole dataset regardless of current page. Why is there such a difference in both the pages?

I have a grid view with manual sorting. In some cells, the data are numeric and datetime. But due to some constrains, the data type on tables are varchar. The problem here is when I sorting those numeric data, it is treated as varchar.Eg: 1, 12, 13, 2, 23, 3, ...But I wanted the order to be: 1, 2, 3, 12, 13, 23, ...I have tried these method, but it doesnt works.

have extended a gridview to have all basic common functionalities like export to excel.So an image button will automatically rendered for exporting the gridview.

I created the link button during overrided grid init method.and rendered during overided render method.I got stuck in this for a whole day..
View 1 Repliesi am creating gridview with dynamic template, and the grid is disappear while postback. my code is below.
i am using GridViewTemplate class to generate Templates

I have a button like this:
<asp:Button ID="btnSave" runat="server" ClientIDMode="Static" Text="Save" OnClientClick="return ConfirmSave();" OnClick="btnSave_Click" />
If I write my client function like the following, it works as expected:
function ConfirmSave()
{
return confirm('Confirm?');
}
But I should check, inside the function, for the confirm result, like this:
function ConfirmSave()
{
if (Page_ClientValidate('validationGroup'))
{
var conf = confirm("Confirm?");
if (conf)
{
$('#btnSave').attr('disabled', 'disabled');
}
return conf;
}
else
return false;
}
Doing this, the page postback but the server click event doesn't fire.

View 4 RepliesI got a strange issue with Gridview in ModalPopupExtender. The OnRowCommand event of the GridView control does not get fired on the first clicking on the button. It will get fired on and after the second clicking.
Code is below.
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);
}
}
AllowSoting is true on every column of my gridvieww.
i want to remove those underlines in everycolumn ...
how can i do that?
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();
}

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?

There is a drop down list in the jquery ui modal form with id - drpAction.When the selection is changed I need to execute drpAction_SelectedIndexChanged function in the code behind. When I just try to invoke the function like onSelectedImdexChanged="drpAction_SelectedIndexChanged" ,the function is not fired.
View 1 RepliesI have been struggling with this problem for a long time. Does anyone have any clue about this problem? I created a gridview and set the allowsorting to true. This gridview has four columns: Name, Position, StartDate, and EndDate. I want the gridview to be sorted on the EndDate.
Inside of the save event, I called the BindGrid() function to rebind the datasource to the gridview. The changes will shown immediately, but the problem is that the records are not sorting on EndDate. I have to refresh the page manually to get the view sorted.

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.
[Code]....
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?
