i want to sort my Gridview rows by a template column that is not bound to any database field. This template coulmn just has a label whose text i set in code depending on a value in a different column that is databound. So am stuck on how to set its sortExpression since its not linked to an column.
View 1 RepliesI have a unbound checkbox column in the GridView control.
When i try to get the value of checkbox in the C# code the checkstate is always false.
I want to check if the Checkbox is selected in a row and get the values of all the cells in that row.
CheckBox chkSelect= (CheckBox)GridView1.Rows[1].FindControl("chkSelect");
<asp:GridView
runat="server"
ID="GridView1"
AutoGenerateColumns="False"
[Code].....
Dim Application = From AL In db.AnnualLeave _
Where AL.Approval <> True _
Select LeaveID, EmpID, Name
GridView3.DataSource = Application
GridView3.DataBind()
after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.
Is it possible that once I have created a datatable programatically, I can then sort that datatable before binding it to a asp:repeater? I have a number of records that I have to get from a com object that has not been eliminated. The com object populates an array, then I loop through the array to pull data from my datatbase, adding the db data to the datatable. Then I bind the datatable to a repeater.
1) the array is multidimensional
2) The COM object doesn't sort the data by company ID (which is what I need to do)
In Datagrid if we are using template column and we have hyperlink and this will have only view or edit whether we can sort it. If so how.
View 4 RepliesI have a gridview control bound to a sqldatasource in c#. In the rowdatabound event I look at a value in a cell and use a function to evaluate the value and depending on that value I populate an added unbound column in my bound datagrid to show an excalmation point. I now want to sort by the column with the excalmation point.
View 2 RepliesI'm new to DataGridViews. I have successfully created an unbound DataGridView that contains columns of string, numeric and date values, but I can't seem to figure out how to define a column as a numeric or date value--only strings. I have enabled sort on the columns so the user can click on any column to sort by that column. When I click on the numeric column, it sorts like:
12345.56
13.35
1442.22
...
The dates also sort as strings rather than dates.What is the code to change the data type of an unbound DataGridView column? Is it possible? If not, how can I do this with my unbound data?
I have a gridview with paging, which displays 5 records in each page.

I have a simple dynamic gridview with following code -

08/01/2015
09/01/2015
but when today is passed then it automatically go to end and next today date is on the top

I 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 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 a question on adding a checkbox to my gridview that is binded to a SQLDatasource control. I have a field called SEL for the checkbox in my table. What I need to do is list the records and be able to check any of the existing checkboxes on any of the rows. When I added the checkbox in there, they are disabled and cannot change them. Is this where I need to use a type of template in the rows? Can they all be allowed to check without turning on the edit for each one individually at a time? I just want to check any needed.This is what I have there now:Code:
<cc1:C1CheckBoxField datafield="SEL" HeaderText="Select" SortExpression="SEL"></cc1:C1CheckBoxField>
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>

Just spent about 8 hours googling and looking through this forum for a solution on how to make sure that I can dynamically sort. Here is the situation.
I have 1 Gridview that displays 10 different scenarios based on what button is clicked.
I am also returning only top 10 records. I am doing all of the data binding pragmatically. So I have BoundFields, HyperLinkFields etc.
I also want to sort some records. When I change DataSource SQL statement the gridview somehow remembers what the last sort value was and it errors out saying that value "x" cannot be sorted because it does not exists.
I tried this:
Tried setting gridview1.sqldatasourceid = null; gridview1.allowsorting = false; gridview1.databind();
Here I get an error that says that the data source does not support sorting? Doesnt it say gridview1.allowsorting = false;
I also tried gridview1.sort("", SortDirection.Ascending); This does nothin... except query my database one more time because i have a onSorting event that looks like this:

Here is an example of just one of those SLQ statements inside GetSQLQuery:

If the grid column is clicked to sort i dont want to retireve data agian, i can get it from viewstate, but i dont know if that triggered the post back or if the ImageButton on the page triggered it
