Which I found useful to create gridview with dropdown filter. What my gridview differs from your one is based on ID, a modal is loaded. E.g. there is a column called "review" and in that column there is image that when clicked it loads a modal with details. My question is, how do i do this using the code provided by you. So ID is passed back to code. (So backend knows which row is clicked).
How can i add Paging for a nested Gridview..

I have a usercontrol with a datagrid that is used throughout my web application. The datasource is passed in a public method from the master page to this usercontrol, as the data selection is different on each page where this usercontrol is used.But by doing this, I'm having a problem with paging, as the datasource is lost after postback. I can't do the data selection in the usercontrol itself as the dataset is passed as a parameter.

I have a listview nested inside a gridview.
I'm trying to get paging working on the listview. I thought that it would display the paging controls, and just page through them normally.
It does display the controls, and limits the result set shown to the appropriate number of records (pageSize) but when I click on the paging controls the grid refreshes and nothing changes with the nested listview (it's still on the first page).
I've tried nesting the listview inside an updatepanel, but the behavior remains. The gridview itself is already in an updatepanel.
So this is the layout I've got:

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:

To sum everything up... My question is: "How to enable sorting and paging for this code?"
I have a modal popup extender with one control (ascx) this control has a label that on onclic method call other popup extender.
It's has other ascx, it's has a button for a search. When I do Click in this button in first time, the event click not fired and there are a javascript error that say "this._activeDRagVisual is null reference".
In the other hand, If a use de second popup inside an asp page the event and control work correctly. The problem is with the popup inside popup.
Altough questions somehow similar to this have been asked for a number of times, but the question is still unsolved. Here is the question: I have a gridview which is contained in a tab container ajax control which itself is inside an updatepanel. Gridview works excellent and its corresponding methods are fired accurately, but when I enable paging, (e.g.) after I click on page 2, the gridview hides itself. here is my PageIndexChanging method:
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
UpdatePanel2.Update();
}
Why paging causes gridview to stop working correctly? What can I do?
I've created a multiple uploadfile user control - upload_multiple_files.ascx:

I have a parent gridview5 with child gridview 6, today i deployed it to our dev server and on that server we have alot more records, so for the nested gridviews i need to enable paging on the parent gridview5. Doing so works fine, until i make a selection within the child gridview6, once any selection is made, and i try to page the page throws an error, i have the following bound to the parent gridview5.

In a gridview there is 4 columns i.e. application no,name,couse,more.. (linkbutton). When we will click more.. button of any application no, then in a popup window all information of that particular application number will show.
View 1 RepliesIn my asp.net Page I am using gridview. I am binding the gridview on page load and on paging event with one method. suppose as Bindgridview1();.
There is one search button for searching the records of user with different method suppose as Bindgridview2(); Â .Â
when I am searching the records with Bindgridview2(); paging doesn't work and directly bind with Bindgridview1(); which is on page load when I clicked next page.
I'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 have repeater in which I have 2 hyperlink in the footer of the repeater and I want that the hyperlink can navigate from the page_load
View 2 Replieshere's a situation and I would appreciate your response.
I have programmatically created the Wizard control:
Page_Load(obj s, evargs e)
{
Wizard ClaimDetailWizard = new Wizard();
foreach(int item in selectedItems)
{
//create new step
//added custom control to new step
//add step to wizard
}
//added wizard to a placeholder on a page
}
Based on List I get from Session i added new steps to my wizard To each step I had added a custom control
Each custom control in tern contains another custom Gridview Control in it.
So here's the problem when the page loads for example for two steps. All is good Wizard does what it's supposed to do.
But when I try to use sorting or paging in that custom Gridview. Somehow it displays the gridview I should see in the next step of the wizard.
Also what I'm noticing through debugging. Is that when I press next in the wizard I go back to the original page where I do all of the code specified above, and it recreates the wizzard. But it goes to the next step. Is this the way wizard supposed to work? Just doesn't seem very efficient.
