I currently am using an ASP.Net gridview control and when a sortexpression is defined on the column, the column header is rendered as a linkbutton. I want to know if it is possible to convert that LinkButton to a Button control and preserve all the functionality.I cannot use TemplateColumns because I using DataControlField implementation to create columns and add them to the grid.
View 1 RepliesI have a gridview control set up like so:
[Code]....
I am using an IComparer to do the sorting of the gridview and binding it to a list of objects. It used to be that the linkbutton in the first template field was being done like this:
[Code]....
The sorting worked just fine when it was like this, but I would prefer not to use a querystring value. The problem with using the linkbutton is that the sorting appears to work (there are only two rows in my test case and they change places), but when the linkbutton is clicked on it is in the same order before the sort took place. After each sort the gridview's datasource is reset to the newly sorted list of objects and the databind method is called.
I have a GridView with 2 buttons to move the record either up or down (changing the sort order). My problem is that on the line "
[Code]....
this will contain Linkbutttons this will contain both image and button will work image button is there that contains Property Alternate Text.
View 5 RepliesI have a asp.net page which has been url rewritten and when im sorting my gridview or paging it via my custom pager it works.
This works fine for first postback to the using the update panel, but 2nd postback the url has changed to the wrong url. When u view source the form action= is still point to correct url, but updatepanel / datagrid is ignoring this and using some other url.
why and how can i ensure this url is always the rewritten version used for updatepanel postbacks?
i have a link button thats text value is populated from a dataset value retrieved from a database. When the user clicks on this link button I want to somehow capture the text value. The trick is the linkbutton is within a usercontrol, and I want to do the processing from the user controls parent. I am able to get the ID of the clicked linkbutton with the use of Request.Form["__EVENTTARGET"];, however i need the text value, in this case its a job number.
I may be able to do this via javascript with the OnClientClick;
OnClientClick='<%# DataBinder.Eval(Container.DataItem,"JobNo","test({0})")%>'
When I do this I get a javascript error saying "M10725"(which is my job number being clicked) is ndefined. I dont know what this means. Do I somehow have to give the linkbutton being click a value?
I have a gridview with four columns, all sortable.
I need to refresh grdiview onbutton click.So if user sorted data by column1 then on button click gridview will be refreshed without sorting (as data comes from database).
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.
Moderators 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 have created an asp.net usercontrol that should list users in a number of applications. For that purpose, the control renders a repeater (foreach application) which in turn renders a gridview (with users for that application).
The control renders fine, except the fact that columns in the gridview are not sortable. Nothing happens (no postback) when clicking the headers. Apparently, no JavaScript is rendered to perform the postback when clicking the header.
This is the code:
[code]....
I have a datagrid that is displaying data that is being returned from a stored procedure. That works fine. The problem is that I want to do sorting. I know that there is sorting functionality in the grid, however, I don't want to go back to the server and get a new set of data. What I want to do is just re-sort the data that is already being displayed.
Basically, I couldn't not find an easy solution to this issue. I tried updating my dataGrid to a gridView control and even that (for my particular issue) was difficult. I wound up un-doing all the changes and just adding another grid that had just the data I wanted for the requirement. If anyone else has an issue like this I would recommend taking it out of a datagrid and writing it in jQuery. I could of written a table that had the data I wanted (and fully sortable using a plug-in mentioned below) in 15 minutes compared to the hours I spent trying to jam a square peg into a round hole.
I have Gridview control which bind data from LINQ datacontext object which use store procedure. sort the gridview using LINQ datacontext object which use store procedure.

View 9 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.
I have a gridview which sources information dynamically from database.Here when i go for the default "AllowSorting" flag equal to true, i am able to achieve sorting of all displayed columns except the textBox control column whose values refreshes to zero.
View 5 Repliesthe structure is like this:
Grivdivew
ItemTemplate
PlaceHolder
/ItemTemplate
/Gridview
And then I try to add some dynamic controls into the placehold control from code behind, I use the RowDataBound Event
Private Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
Dim ph As PlaceHolder = CType(e.Row.Cells(1).FindControl("PlaceHolder"), PlaceHolder)[code]....
The problem is the button CommandName is not functioning. And more strangely, if I add the button manually into the placeholder, like this:
Grivdivew
ItemTemplate
PlaceHolder[code]....
I have put my gridView inside an UpdatePanel with Timer control for auto refresh.The gridView has a linkButton column which is bounded to referenceNo column from database.
On click of this link button i want a panel to get visible. This Panel contains details corresponding to the referenceNo shown in differnt controls (mostly texboxes). Do i necessarily need to put the panel inside the Update Panel.If not how do i do it?
I have tried putting panel outside UpdatePanel, but it doesn't show panel on clicking the linkbutton nor does the values are updated inside this panel (if panel's visibility is set to true by default for testing purpose).
i have added a hyperlink in the gridview and i am displaying the image names in the grid as hyperlinks
when i click on the hyperlink in the grid, the related image has to be displayed in the same page but in another div which is next to gridview
but for me ,image is displaying in another page
I want a hyperlink that looks like a standard button. I have tried using a LinkButton but can't get it to look like a button. It always seems to stay looking like a hyperlink. I don't want to set an image to do this.

am using vs.net 2005 wit c# In my web application we used master page and child pages. In master page we have the search option ( a textbox with serach button). when user enters something into the text box and press enter then i should display the search result.So i placed that in a panel (in master page) and set the default button as Search button. My Problem is i have other hyperlinks and linkbuttons in the master page and in child pages. when am clicking any other hyperlink or linkbutton the search button is getting activated (not the respective one). How to solve this?
