i want to load a usercontrol that contains a gridview with paging and sorting capabilities without postback.
Code for Load UserControl in case Dynamically is:
[Code]....
I need to insert some JavaScript code inside a UserControl that I load from an Ajax call via jQuery Ui Tabs. Let me explain... This is my View (with jQuery loaded)
<script type="text/javascript">
$(document).ready(function () {
$("#tabs").tabs({
cache: false,
});
getContentTab (1);
});
function getContentTab(index) {
var url='<%= Url.Content("~/Home/getUserControl") %>/' + index;
var targetDiv = "#tabs-" + index;
$.get(url,null, function(result) {
$(targetDiv).html(result);
});
}
</script>
<div id="tabs">
<ul>
<li><a href="#tabs-1" onclick="getContentTab(1);">Nunc tincidunt</a></li>
<li><a href="#tabs-2" onclick="getContentTab(2);">Proin dolor</a></li>
<li><a href="#tabs-3" onclick="getContentTab(3);">Aenean lacinia</a></li>
</ul>
<div id="tabs-1">
</div>
<div id="tabs-2">
</div>
<div id="tabs-3">
</div>
</div>
With these lines of code I call the Ajax function to load the content into a DIV.
This is the Action from the controller:
public ActionResult getUserControl(int num)
{
return PartialView("TestUC", num);
}
And this is the UserControl...
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
Number... <span id="testSpan"><%=Model.ToString() %></span>!!
<input type="button" value="Click me!!" onclick="message();" />
<script type="text/javascript">
function message(item) {
alert($("#testSpan").html());
}
</script>
The problem is that the message() function returns always 1 (instead of returning the correct number). My question is... How should I add the script to my UserControl in order to have my code running correctly?
I want to use same functionality in Ajax:Accordion. Looking for the code for this as well as instead of label in user control i want to bind the grid view.
View 1 RepliesModerators Note: THIS ISSUE IS BIG FOR ME AND EVEN IF POSSIBLE, GET THE REPLY FROM THE DESIGNER OF GRIDVIEW. I have been looking for him for long. I am really fed up with reviewing a good lot of web pages on how we can possibly customize the gridview to enable sorting and paging. So many sites have listed out a lot of information and so many guidances. But the problem is that one works out fine and the other is a burden. I really feel bad about being given the job of customizing this kind of a gridview which has no user friendly approach to it. Also, this control is rendered without the pager links inside the <tfoot> tag. I have tried the Pear Pager in php. It is that good and easy to use and compared to that, the gridview in asp.net is the worst ever control i have ever tried so far.
1. i can use the images to indicate the sorting direction
2. I can have the custom pager like
[code]
<<Previous 1 2 3 .. 7 Next >>.
[/code]
When i click the next when i am viewing the page at 3 , the pager links should change as
[code]
<<Previous 2 3 4 .. 7 Next >>
[/code]
Kindly look into this type of requirement and firstly tell me whether this is possible with the gridview control. I would like this request even to be escalated to the designers of the gridview control also, so that Microsoft comes out with a reply THAT WORKS and not the kind of stuff like surfing through a lot of links and pages and finally wasting a lot of days precious time and still breaking the head with this useless control. I have spent a lot of time in searching for a perfect way. Not writing a code that is non-standard. I am really serious b'cos I have spent weeks in customizing this control. If I dont get a solid reply atleast now, I am going to generate all the output by HTML content by custom coding.
i am building my objectdatasource dynmically when certain buttons are clicked on the page.. and with that the gridview is being displayed with the results of the objectdatasource that was built.
So my gridview code looks like this:
[Code]....
How can i enable sorting and paging if the datasource is being built on button click event?
I have UserControl that has asp control(<asp:Button runat="server" ID="btn" />) and I want to render it.
I tried 1
[Code]....
It doesn't works because it says that each control that has runat="server" must be in Form.I also tried 2:Because loader.Form is null, I create HtmlForm and added the ctrl to it and then added HtmlForm to loader's Control, BUT it says that it has 2 HtmlForm. So, instead I "injected" HtmlForm to loader like this
[Code]....
Now no error is occurred, BUT StringWriter is empty. don't tell me to add Page to solution and override OnRender. I want to do it as I mentioned above.
When it comes to the usercontrol specially when they are loaded dynamically on the basis of certain conditions then it becomes a very confusing work. I have read in many forums that the dynamic controls have to be loaded in OnpreInit or OnInit. Some of those links are[URL] But this is useful only when if the we know that we have to load UserControl1, UserControl2 without considering any conditions. But what if I have a Tab control and for each Tab Click I have to load the UserControl dynamically. In that situation how can we add the control in either OnPreInit or OnInit. If I am not mistaken then in such case, then we can add usercontrol in certain events. If we are using a TabControl then we load in Tab_Click , if we are using Menu Control then we use Menu_Click and depending
upon the particular tab or Menu we load associated usercontrols. Hence in these conditions, how can we go with the logic mentioned by above links. I have this confusion for very long time . I am posting little portion of my project here. I am using RadTabControl but it doesnt matter if it is Microsoft TabControl. In the aspx, I have a code to define RadTabControl.
<telerik:RadTabStrip
ID="tabMemberDetails"
runat="server"
Skin="WebBlue"
MultiPageID="tabDetails" SelectedIndex="0"
Align="Justify"
ClickSelectedTab="true"
EnableViewState="false"
ReorderTabsOnSelect="true"
Width="1139px"
OnTabClick="tabMemberDetails_Click" ScrollChildren="true">
</telerik:RadTabStrip>
In the code behind, I am loading usercontrol on the basis of the particular TabClick. tabMeberDetails_Click fires whenever I click on the tabs.ViewState["ControlName"] stores UserControlName on the basis of certain condition and finally i load the usercontrol.
proteced void tabMemberDetails_Click(object sender,
RadTabStripEventArgs e)
{
Conditions......
{
ViewState["ControlName"]=........
}
viewDef=ViewState["ControlName"]
UserControl control = (UserControl)LoadControl("~/Controls/"
+ viewDef + ".ascx");
after this I add control to the RadTabStrip.................. and call bind method.........
}
As you can see from above, I am loading my usercontrol in tabMemberDetails_Click event. I see no other choice to do it in OnPreInit. Can anyone answer if this is the right way to do or there is another way that complies with the logic in the links given above.

How can I pass the title value ?
It has been more than 2 days since I had started searching for the answer and I still don't know how to do it.
I have empty gridview that is filled with data depending of the parameters given. The gridview is used to track changes user had made to the database.
In the first dropdown list the user selects from which table (or all tables) to display the data. From the second dropdown list the user selects from which column (or all columns) of the previously selected table to display data. In the first textbox the user enters the search term and in the third and fourth textboxes the user enters the date range in which the changes occurred.
After clicking button the data within the given parameters should be displayed. The problem is that data is displayed fine, but I can't manage to get sorting and paging to work so if possible, give concrete answer because I'm pretty sure I googled one half of the web during these 2 days. :)
Here is the code for the .aspx file:

Here is the codebehind:

To sum everything up... My question is: "How to enable sorting and paging for this code?"
I am using ASP.NET 4.0 with C# (Visual Web Developer 2010 Express).
I have successfully managed to implement a simple GridView bound to a stored procedure data source using declarative ASP.NET code as shown here:
<asp:GridView
ID="grdTrades"
runat="server"
DataKeyNames="tradeId"
EnablePersistedSelection="true"

Can someone point me to a tutorial that shows how sorting is done with small images showing the sort direction. I'm using linq-to -sql so I'd like something that shows how dynamic linq works.

View 2 RepliesI'm trying to extend the GridView control to enable sorting and paging for any situation.
When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?
To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.
Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.
My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.
The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,
[Code]....
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.
I want to use a gridview with sorting and paging to display data from an SQL server, the query uses 3 joins and the full text search containstable. The from part of the query uses all 3 tables in the join.What is the best way to do this? I can think of a stored procedure, SQL directly in the SQLDataSource and creating a view in the database.I want good performance and would like to leverage the automatic sorting and paging features of the gridview as much as possible.
Edit:About size, I suspect very few records, total about 1000 and a query would typical result in no more than 100 records and most times much less.
perform the paging and sorting in grid view programatically..

I am having a gridview with an object datasource binded in the markup(aspx page).When page loads it directly works fine with all sorting and paging properties.However, i need to filter display on gridview so i have to change the datasource of the gridview on the code behindIt works fine.. i mean the filtering and displaying is good but paging and sorting doesnt work.
View 1 RepliesI am binding DataView data to GridView and using paging and sorting mechanism of the GridView.
In case of sorting, I define the sort expression based on user's selection and assign the same to DataView and then bind the same to GridView.
Issue:
Everytime I sort the DataView, I see different set of rows on the same page on GridView. The issue is, the column which is used in sorting has many rows with same values. So everytime I sort DataView using sort expression and bind it to GridView, it displays different sets of rows and sorts randomly.
What should I do to make sure that it always display same rows? I cant change the sorting expression as it is selected by the user. Or only way is to append sort expression containing unique key internally ?
I need the consistent set of rows as I am operating on rows selected by users and make them editable and allow user to udate values and display the same.

I have a problem with the allow paging and sorting in the gridview. I have a button to export the gridview data to excel and I need to disable the paging and sorting in code behind. When I export to excel it have the link numbers of the paging and the column header as a link to sorting. I'm using VB.

I don't get the paging and sorting disable.
I'm coding a report page.In this page,there are two date fields for user to filter the date and the GridView is filled depending on these dates in the CodeBehind (When user click the button view).Now I want toimplement a paging/sorting feature for this GridView.I've researched and see there are default paging for GridView which is not very efficient (my report table may have thousands of records) and custom paging but this requires using ObjectDataSource (which I don't use).Thus anyone can recommend me some approaches that are best used in this situation?
