i am using the inbuilt database in VS08. I was trying to write code to query Gridview control to show only those rows whom i specify through my Query.
I searched for it and found some code which might work for External databases. But found no code for inbuilt database MS SQL Server provided in VS08.
Also there is no such method available for GridView1 object.
I came across a situation where a user selects no of rows from dropdown , depending upon the user input, automatically that no of editable rows should appear to input data...(maximum 8 rows only)
View 1 RepliesI have a gridview which right now is getting loaded with four pages of data. There are 50 rows per page. My problem is I need the "select all" button on my page to select 180 rows, not just the 50 on the page. This is my javascript:
Code:
function sel() {
var frm = document.forms[0];
isSelected = !isSelected;
for (var i = 0; i < frm.elements.length; i++) {
var e = frm.elements[i];
if (e.type == 'checkbox' && e.name.indexOf("ckSelected") > -1)
e.checked = isSelected;
}
}
I am more a C# person than javascript, but I am deducing that I need something other than document.forms[0] to represent the entire gridview. Or perhaps, I can't do this in javascript at all. Do I need server code to run and set a session variable, then when the user clicks the button to do something with all his selected rows (it goes to a detail page), query that session variable to see if it's all rows instead of iterating through each gridview row individually to see if the checkbox is checked?
I am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
Is it possible to select multiple gridview rows using Ctrl+Click and then delete all the selected rows with a button?

Is there a way to select the number of records/rows to display in the gridview by a drop down list
View 2 RepliesI have a GridView with an extra checkbox column to select rows.
To select multiple rows, the user now has to click each separate checkbox, but I would like to offer the possibility to select multiple rows at once using Shift+click.
Thus the user would explicitly select the first row with a single click and the select the last row using Shift+click. And the checkboxes of the rows in between would then automatically be checked as well.
