View 2 RepliesIs there a way to use the GridView paging and having the links not use JavaScript. So that when you click on the page number 5 (for example) that link is a hyperlink.

View 2 RepliesI am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
I am using this signature control. Here's the web.forms code...

I have a webform that has a bunch of textboxes (name, address, city, state, ect...) and a gridview that holds records of products (name of product, stock number, qty, ect...) How can I get all of this information into a csv file when the customer presses a "Place Order" button? Does anyone have an example in vb?

What is right way to send visitors from one webform to other. What are their limitations and their plus points.
View 2 RepliesI will start a new project in a couple of weeks and I have some questions about ASP .NET WebForms. Visual Studio ofters some nice wizards such as the SqlDataSource component that you can assign to a GridView and then you can edit and delete rows without coding.
The disadvantage of these wizards is the bad seperation between the layers and thereby the maintance of the software. One good example is the SQL statement in the view (*.aspx files) and so on. I would like to ask you how you handle this in your projects. Do you use the wizards? Otherwise if the wizard would not be used then it is a lot of effort necessary to program all features of the GridView component self. Such as edit, sort, paging etc. Is there information available how you can do this? I didn't find really something. What is your opinion about this.
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 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(); .
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 a GridView that is populated via a dataset that contain 1 table. I have enabled paging on my GridView.
In my Updating event, I handle the new values and call a store proc to update my database with the new values for the selected row. In order to minimize the call to the DB, instead of getting back a new dataset with the updated values, I simply update the row of the dataset that I have in session with the new values and then I bind back my gridview.
The problem that I have is since I have let's say 5 pages of 10 row... If I update a row on the first page as soon as I click update, the gridview will show the new values. However, if I select page 3 for example, click on update and update the values, once the update is done, the gridview will still be displayed with the old values.
My question is, can I control the style of the paging element separately of top and bottom, I have set the paging to appear in both top and bottom of the gridview, and I want to see that the top pagination is little high up in the page, to do that I used the cssClass and set margin-top:20px and made the position: absolute, this does change the position of the top paging area and set it rightly for me, but the bottom pagination has also come up as a result and now sits inside the grid data!!

View 8 RepliesI hoping someone could answer a question for me. I am relatively new to developing web applications with .NET and I have question I can't seem to find a straight answer to. When allowing paging of a GridView control, how does retrieve the data per-page? Is all the data stored into an object, and then displayed x amount of rows at a time? Or, when moving from page to page, is it executing each time but restraining the result to the specified amount of rows?
View 7 RepliesI have followed Custom Pagination article to implement the custom pagination using GridView.
I have also done custom pagination using the DataGrid but i am still confused on following things.
DataGrid which is there in the ASP.NET 1.1 having VirtualItemCount which is set to render the pagination interface [1 2 3 4 5 ... something like this] GridView does not have the above mentioned property then how to generate the pagination UI?

protected void Page_Load(object sender, EventArgs e)
BindGridFunction();

I have an ASP .NET GridView with Paging. One column in it has a CheckBox. In a certain scenario, I want to uncheck the checkboxes that are checked.
foreach (GridViewRow dr in gvMyGridView.Rows)
{
if (dr.RowType == DataControlRowType.DataRow)
{
if ((CheckBox)dr.FindControl("chkIsApplicable") != null)
{
((CheckBox)dr.FindControl("chkIsApplicable")).Checked = false;
}
}
}
But unfortunately because of Paging only the records that are currently shown in the Grid can be accessed in this way. I want it to apply to ALL the items in the GridView. This should happen client side and when the user commits will get saved to the database.
I am working on a small project that requires gridview paging for upto 100k records. what are the ways i can improve the performance. I tried to page using sql server with Temp table but it still is a bit on the slower side.
