Help with Dynamic Controls in ItemDatabound

I am trying to retrieve the values of dynamically created controls in a Radgrid. I have read dozens of posts similar to this, but cannot seem to sort it out.

Here is the scenario:

I have a Radgrid on my page with static GridTemplateColumns setup
In one column I have a blank ItemTemplate
OnItemDatabound (which happens as an AJAX callback) I insert a dynamic control, and potentially set it's value (e.g. textbox, datepicker, combobox). This control type is based on the data - so I cannot do this in OnItemCreated
Everything looks right when the screen comes back - I have a grid with custom controls in each row, and the proper values all set
Then you do some other things on the screen - and eventually click SAVE
On Save I loop through the Radgrid items, find the controls by ID and retrieve their values - to then save off

It is the last part that has me stumped.

At first I was getting a null reference to the controls - and found that my dynamic controls where not in the GridItem container where I had created them.

After a bit of reading, I added code that loops through and re-initializes the controls in the grid. To do this I Rebind the Radgrid right before looping through the Radgrid items, setting a flag that has the code in ItemDatabound only create the Controls with the proper ID and then .Adds() them to the GridDataItem - skipping the parts that set the default values of the controls

At this point I can now get the control with .FindControl(myID) - but the .text or .selectedvalue, etc is null.

Is this kind of scenario supported with the RadGrid and AjaxManager?

.Pageable in a Grid

Hi all

I have a problem.
In my Grid i have the following Code for the part whit the pageable:

.Pageable(paging =>

paging

.PageSize(500)

.Style(GridPagerStyles.Status)

.Position(GridPagerPosition.Bottom)

)

Now, when I have more than 500 Items, I can't go to this, then I don't allowed to click to another page in the part of .Style(...).
What can I do, to ask the Grid how many Items that I have, and when it's more than the 500, I allowed the paging?
But only in this situation.
If I have less then thes 500 I would not to enable and see the Paging. Then I will only see the number of Items...

Thanks
Marco

export data from excel file and import to sql server

Hi

I am using RadUpload to upload an excel spreadsheet file to a web server.
I then want to map the columns to a database table and import the content to a database,
in code behind. (preferably VB)

I feel there must be some existing code or a third party component to do that, but I have
not been able to find anything. Can anyone give me some pointers?

OK I can write the code, but this must exist somewhere already.

Thanks

Clive

Database Identity Seed

Hi,

I have a short form that the end user fills it. When he hits the 'submit button' it saves the fields into a database table and it returns it's identity seed.
Now I added the RadAsyncUpload control, and need to associate the seed of the form with the uploaded file.
The problem is that the RadAsyncUpload.FileUploaded event runs before the 'submit button' event.

What is the workaround for this case?

Protected Sub RadAsyncUpload1_FileUploaded(sender As Object, e As Telerik.Web.UI.FileUploadedEventArgs) Handles RadAsyncUpload1.FileUploaded

Dim targetFolder As String = RadAsyncUpload1.TargetFolder

Dim newName As String = hdnPesquisaID.Value & System.Guid.NewGuid.ToString

e.File.SaveAs(Path.Combine(Server.MapPath(targetFolder), newName + e.File.GetExtension()))

End Sub

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

hdnPesquisaID.Value = "returns identity seed from database"

End Sub

RadGrid Broken after Update from Q3-2012 to Q1-2013

I spend all morning updating resources in my app and debugging. And after I finally got my project to successfully rebuild, I have a very dynamic RadGrid that has two problems.

Now keep in mind the code has not changed and it has always worked fine. I don't know if these issues are related or not. I can provide code, but I didn't make any changes. I did run the Telerik Upgrade Wizard, but I don't think it would have changed lines of code in my apps.

1. I dynamically set images and Hyperlinks in a Hyperlink column. After the updated my images are not showing. And my assigned URL/Links are not updating.

2. When a filter is changed, the results are not being updated. The page refreshes the records load but the filter criteria is not behaving. I put a postback button in to try to catch the problem and I can't figure it out. Eventually if I postback the filter is passed and loaded.

Is there anything anyone can recommend to check or try? I'm about to do a system restore and revert back to my old 2012 version, I'm kinda freaking out because I have a lot of work that is not functioning now and I need to do an update on the production code.

Thanks
Jason
