View 2 Repliesi only found websites that uses the XMLHTTP request to call an aspx page or what ever page ( make a request to a page that appears the piece of data in a div or so )but i have a question is it possible to use it to bind asp.net server controls Examples 1- bind a gridview or datalist from this XMLHTTP request 2- after click an edit button in a grid can i use XMLHTTP request to fill some text boxes and dropdowns and other asp.net server controls 3- can i use upload files using XMLHTTP request i want to know if this is possible or not because Ajax and update panels are very slow and affect the server and client performance is there another alternative if my senarios are imposible with XMLHTTP request where can i learn about this alternative if this possible where can i learn more about this XMLHTTP request with asp.net server side controls instead of ajax and updatepanel
View 1 Repliesi m trying to something new for myself...actually before some day i post a thread that how to fire item command event of Runtime genrated datalist, in this datalist i creating item template and hadder template at runtime, and in this item template i m creating a button at run time.No problem was that i cant handle the item command event of datalist through that button, but no luck, no one show thir interest and i couldnt find any thing regarding this.so i decided to do the work with client side ajax scripting, i found a liitle bit success, now i can delete the particular record from the database. but now problem is that i cant rebinding the datalist again, with new updated dataset.
my code is here..
aspx:--
[Code]....
function addToFavorites(prod, box) {
var favPage;
var response;
if (box.checked == true) {
favPage = "xyz.aspx?type=add&product=" + prod;
} else {
favPage = "xyz.aspx?type=remove&product=" + prod;
[Code] ....
I am using the above javascript to call a page on check box click.It is working fine on my visual studio project.
But when i deploy that it is not working.javascript is calling but not able to call that page.
I am using visual stuido 2008 / 3.5 Â as my development server.
I have a page that has 3 to 4 divs with gridviews in each that get data loaded using Ajax Xmlhttp calls.
Now the problem is that I have checkboxes in the grid and need them to be disabled/enabled
when they load to the main page in the div.
When i set the Enabled=false tag in the ASPX page to the checkbox, the UI throws an "Object required" error.
I have many divs in 1 page and each div consists of a gridview, the gridview is loaded by making AJax calls. On load of the page, all the grid load data properly. But now when i update any row in either of the grids, and make a call to the javascript that loads the grid in the page, it doesn't work rightly. Wat are the options to update/refresh the grid.

View 1 Replieshow do I bind a DataGrid to a collection? (e.g : List ). i used this :
Datagrid dg = new Datagrid();
dg.DataSource = myCollection;
dg.DataBind();
but after this, the Datagrid still doesn't display the data from the collection.
I end up with a row for each object in the list, and any cell in a given row is bound to a property of the corresponding object.
However, suppose one of the properties of my object is a dictionary, and each is expected to contain a specific key. Is there any way to bind one of my DataGridColumns to that dictionary key?
Let's say I have a DataGrid that looks something like:
<asp:DataGrid ID="SomeDataGrid"
runat="server">
<Columns>
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="Data"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
In this Grid, I set the datasource to some collection that contains a public property called "Data" and do a databind(). Every works as expected.Now let's say I want to set the DataField attribute of the column to a public member, or a property, or some other thing I've computed. What is the easiest way to go about this without creating intermediate objects or adding public properties to the objects in the collection?So what I want to do is something like:
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="someMethod()"></asp:BoundColumn
I have a datagrid called studentAddList which is combined by 2 tables. Now I have a reportviewer called ReportViewer1. They are both placed on the same page. Now I would like to bind the datagrid studentAddList to the reportviewer ReportViewer1. The reason why I bind the datagrid to it is because I have some filtration on the data.

View 1 RepliesI have an ArrayList of strings called 'vins'. I have set DataGrid1's data source set to 'vins'. When I check off create columns automatically at runtime the DataGrid is populated with the correct values from the arraylist, however I'm not sure how to reference them. I'm trying to make it so that a user can click on a link after any VIN number and have that referenced and deleted from the arraylist. bind this ArrayList to the DataGrid and then be able to reference them.

View 1 RepliesI've successfully used the xmlhttp object to redirect (xmlHttp.open) user to another page but I have the following issue ..I have a classic ASP application that has some very antiquated "admininstration" functionality built in that loops through a SQL table with NT Accounts and allows the link to only be visible to users with NT account in the table. We have since moved on to manage permission to our .net apps using an object that looks for your NT account in an Active Directory Group. So, I would like to use the .net object to return True if NT account is a member of the group and then display the link (which is in the classic ASP page) if the .net object returned true.I don't know if that can be done .. I just know I'm able to return the TRUE value using the xmlHTTP ajax object but I only want to set visibility of a link rather than xmlHttp.open to redirect to another page.

Datagrid is in content,When trying to access client side function for the cells in the datagrid,its always showing at 0 position suppose i have 10 rows,for each row "Test button" i should invoke the client side java script. For each row "Test button" client side script is displaying message at first row only.
in datagrid i am binding the description and button to every row in datagrid
so i have added Testbutton.attributes.add("onclick","return javascriptfunction();"); in datagrid_itembound.Iam showing one div in client side function but that is working only for one row,when iam trying to click test button in second row,itsshowing that div in first row instead of second row
i want similar functunality like displaying of flag button in stackoverflow.
I have a datagrid control which is bound to a table which containing more than 1000 records. And i want to show only 25 records once a time. I have used paging in datagrid. But each time the next page index is set, query is fired again. This takes lots of time. So what is the easiest way to bound data in this case to improve performance.
