EnableViewState causes the grid to maintain its data without having to rebind, which would wipe out any of the changes that were made, the original problem you were having. There are ways to do it without viewstate, but they are much more complicated.

I didn't get this.
and whether your sp has returned tables or not? To check this, do like this
dataset.tables!=null and dataset.tables.count >0
dataset.tables[0].rows
your code will through an exception if no table is returned

Hello
thanks for your reply,Its working fine,all i want to know is under what circumstance my select query in the stored proceure will not return even the name of the columns(for which i am using ds.tables[0]!null)
|

There would be no case that I can think of were this would occur. If your proc returns a resultset then you will have columns and names.

If there is some exception occured in your stored procedure while query execution then it may not return the columns also. The probability is high for a long SP or complex queries.

Hi people, maybe somebody knows to help me out. I have 2 problems:
1. How i can pass value from Page to a User Control maybe with a Event Delegate?
2. In the code below i have a user control, but I can not access it in the code behind and in the designer it is not registered.
But as soon as I remove my update panel and repater it is visible or can be accessed on it. Why?
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<div>
<asp:Repeater ID="RepeaterSkillGroup" runat="Server">
<ItemTemplate>
<div class="Box">
<div >
<MuM:SkillGroupControl ID="SkillGroup" runat="Server">
</MuM:SkillGroupControl>
</div>
</div>
</ItemTemplate>
</asp:Repeater>
<asp:HiddenField ID="HiddenField1" runat="Server" />
</div>
</ContentTemplate>
</asp:UpdatePanel>
thx a lot!

- One simple way you can do it, Have a public property in usercontrol which takes the value that you want and pass it from the page.
-Muc_ wrote: 2. In the code below i have a user control, but I can not access it in the code behind and in the designer it is not registered.
We cannot access directly any item that is in repeater.If you want to access it then you have to find it dynamically from codebehind using findcontrol.You can find it in itemdatabound of repeater.
Actually when we bind a datasource to repeater, the number of rows is created based on data and for every row sepearte control is created, so to access these controls you can access using find control in itemadatabound.
for details Have a look

Butt how should i add a EventHandler from usercontrol in my aspx page in the Repeater if I can not find it?
|
|
|
|
|
You add a event itemdatabound in the repeater,which is on your page.And in this function, find out your usercontrol as
SkillGroupControl ctrl= (SkillGroupControl)e.Item.FindControl("SkillGroup");
|
|
|
|
|
I had this event already knew that but not if I set a property of the control is static that the value is also reingespeichert.
I had this event already knew that but not if I set a property of Control that the value is static stores even.
protected virtual void RepeaterGroup_ItemdataBound(object sender, RepeaterItemEventArgs e)
{
MuMSkillGroup group = (MuMSkillGroup)e.Item.DataItem;
SkillGroupControl currentGoup = (SkillGroupControl)e.Item.FindControl("Skillgroup");
}
But thx a Lot!

Hi there,
I know that this subject has been discussed for many times but still I do not have my solution.
After I have followed the next tutorial
http://msdn.microsoft.com/en-us/library/879kf95c.aspx[^]
I still want more flexibility.
What I want? I want that users to login with their username and pass, and also an extra Company ID.
So that is why I would prefer(if it is ok) somehow to save it in aspnet_Users .
Then: what changes should i do in order that at the registration step to include this extra field? I do not want any extra step. All requiered the sime time.
Here is what I have changed:
within CreateUserWizardStep i have included:
<tr>
<td align="right">
<asp:Label ID="CompanyIdLabel" runat="server" AssociatedControlID="CompanyId">Company Id:</asp:Label>
</td>
<td>
<asp:TextBox ID="CompanyId" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="CompanyId" ErrorMessage="CompanyId is required."
ToolTip="CompanyId is required." ValidationGroup="CreateUserWizard1">*</asp:RequiredFieldValidator>
</td>
</tr>
and added an extra field in aspnet_Users
Also keep in mind that I am a very newbie in asp.net, the 2nd day only

Then this is probably something you should not be tackling.
You can add the column to the aspnet_db database but then you would need to create a custom membership provider and implement the ValidateUser method to check the new field
http://msdn.microsoft.com/en-us/library/system.web.security.membershipprovider.aspx[^]
Alternatively, you could handle the Authenticate event form the login control and manually check the field in the database. Although this is less extensible than the previous method.

I have changed my mind and I have realized that I need in fact to save all data in my own database. Now how do I do that?

1. you should force to have session timeout value set. ie allow system to expire Session value after some predefined time.
2. In each web page you should check(preferebly as first line of code in page load event handler) before doing anything check if session is null then redirect user to login page.
make sure that both has been implemented in your case.
Thanks,

There is no direct method that you can do.
You need to loop through all column of source tables and need to create a new table having new column structure(have all column). Then using some for loop you need to add rows, again by calling source tables rows.

hi,
I want to implement a dicom viewer using asp.net + C#.
i want it for my web application.
I am new to this one.. Plz help me..
|
|
|
|
|
Sorry I might not help you  but I am interested to know what is 'dicom viewer'?
Thanks,
Arindam D Tewary
|

|

hi, happy to see Ur interest. 
Dicom viewer is one type of codec for displaying dicom images(one type of image format).dicom images specially used in medical science. like CT scan,Brain etc.
|
|
|
|
|
Hi,
did you find any control to show this kind of images? i'm interested to know more
Regards,
Jamil
|
|
|
|
|
If you are just interested in displaying dicom images, you can export or extract the image inside the dicom file, in .BMP, .JPG or whatever format you want, and use any regular image viewer.
I´ve done some tests using this approach and binding images to asp:image and ImageButton succesfuly.
If you tell me how are you dealing with dicom files (if you are using some library or stuff like that), i might help you with this topic.
Regards,
Pablo.-

I'm tryin to add a custom attribute in the html of a TextBox control in an asp.net page, like the following:
<asp:TextBox runat="server" ID="txtUserName" myAttr="10" ></asp:TextBox>
when i try to change this attribute from javascript and then read it in the code-behind, i dont get the changes, however if i changed any of the other control attributes like value, it works just fine. i dont know why i cant add my own attributes.
is there anything i should do to tell the asp.net to render my new custom attribute to the viewstate so i can read it later in the code-behind?
i would appreciate any help.
thanks in advance.
