I apologize in advance for the detail in this post...but w/o it, I don't think it will be clear. (code snippet below)
I have been trying to follow an example discussed at http://msdn2.microsoft.com/en-us/library/ms972948.aspx. I have a very similar application - attempting to update a row in a collection of objects bound to a GridView object through an ObjectDataSource. I have 2 methods on a DAL object that I have provided for the ObjectDataSource: getALMPropDataTable() and <b>updateALMProp( int almPropNbr, String almPropNm, String almPropVal)</b>. The getALMPropDataTable() works perfectly, no issues. However, when attempting the Update, a problem arises...
1) Clicking the Edit Button (1st col) of the GridView seems to work OK...and the one column that is editable appears w/ a TextBox - no problem there.
2) In this mode, the Edit Button is replaced w/ an Update and Cancel Button pair as expected - no problem there.
3) When clicking the Update Button, the updateALMProp( int almPropNbr, String almPropNm, String almPropVal) method is called (as expected), however, Trace.Warn messages that I have placed just inside this method reveal the following:
ALMPropVwDAO.updateALMProp() from DAO Layer...
<b>almPropNbr: 0 almPropNm: almPropVal: stuff</b>
Only the 3rd argument is received. No matter what row I attempt to update, I get this same behavior (the 0 value of almPropNbr is always zero regardless of row since this type is Int32 - ie: I don't get the row number as expected). The almPropNm value is empty (it should be name of the property... so that's a problem). Only the value typed into the TextBox on the row in Edit mode actually comes across. The almPropNm is actually the key needed to get the right object of the collection, so consequently no update can performed (the almPropNbr value is technically not required for the update, it is just a row marker for log tracing). If anyone has any ideas, I'd appreciate it...thanks in advance.
Here's the aspx file:
<asp:GridView ID="GridViewALMProp" runat="server" AutoGenerateColumns="False" Width="400px" BackColor="White" BorderColor="#999999"
DataSourceID="ObjectDataSource1" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" ForeColor="Black" GridLines="Vertical"

<asp:BoundField DataField="ALMPropNbr" ReadOnly="true" HeaderText="Number" SortExpression="ALMPropNbr" />
<asp:BoundField DataField="ALMPropNm" ReadOnly="true" HeaderText="Property Name" SortExpression="ALMPropNm" />
<asp:BoundField DataField="ALMPropVal" HeaderText="Property Value" SortExpression="ALMPropVal" />
</Columns>
<PagerSettings Mode="NumericFirstLast" />
</asp:GridView>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" TypeName="ALMPropVwDAO" SelectMethod="getALMPropDataTable" UpdateMethod="updateALMProp">
<UpdateParameters>
<asp:Parameter Name="ALMPropNbr" Type="Int32" />
<asp:Parameter Name="ALMPropNm" Type="String" />
<asp:Parameter Name="almPropVal" Type="String" />
</UpdateParameters>
</asp:ObjectDataSource>
Here's the method called:
public static void updateALMProp( int almPropNbr, String almPropNm, String almPropVal)
{
HttpContext.Current.Trace.Warn("ALMPropVwDAO.updateALMProp() from DAO Layer...");
HttpContext.Current.Trace.Warn("almPropNbr: " + almPropNbr + " almPropNm: " + almPropNm + " almPropVal: " + almPropVal);
try
{
// get ALM object from Session
ALM alm = (ALM)HttpContext.Current.Session[RequestConstants.ALMObj];
HttpContext.Current.Trace.Warn("ALM from Session: " + alm.ToString());
ALMProp[] almProps = alm.ALMProps;
for (int i = 0; i < almProps.Length; i++)
{
HttpContext.Current.Trace.Warn("almPropNm: " + almPropNm + " | " + "almProps[i].ALMPropPK.ALMPropNm: " + almProps[i].ALMPropPK.ALMPropNm);
// find entry in ALMProp Array and update value
if (almProps[i].ALMPropPK.ALMPropNm.Equals(almPropNm))
{
HttpContext.Current.Trace.Warn ("found ALMProp[] object, i= " + i);
almProps[i].ALMPropVal = almPropVal;
}
}
alm.ALMProps = almProps; // set updated Array back on ALM object
// place ALM object back on Session
HttpContext.Current.Session[RequestConstants.ALMObj] = alm;
}
catch (Exception)
{
}
}

I got this resolved...I battled this issue for an entire day trying to figure out what the issue was and found that the single attribute DataKeyNames was missing...when you use a GridView to handle SELECTS, this is of course not required. I found the documents at http://msdn2.microsoft.com/en-us/library/aa905796.aspx to be EXTREMELY helpful. Hopefully others will find them helpful as well...

Check if the ContentPlaceHolder control is inside the form tag. If not, put it inside the form. It should look like this:
<form id="form1" runat="server">
<!-- Html and ASP.NET markup -->
<asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server">
<!-- Put controls here if desired -->
<asp:ContentPlaceHolder />
<!-- Html and ASP.NET markup -->
</form><pre>

hi,
i have a checkbox list, and having values like,
Company1
----------------
1 - car
2 - bus
3 - both
Company2
------------------
1 - car
2 - bus
3 - both
Company3
------------------
1 - car
2 - bus
3 - both
and these values are repeating for many Companies so my client can select Car or Bus or Both from a Company, but what if he/she selects Both then logically the Car or Bus Option should not be selectable, how i can achieve that.
I love .NET

if you have only these options then use radiobuttonlist instead of checkboxlist.
If you still want to use the checkbox then you have to write a javascript code for onclick and check which checkbox was clicked and uncheck all other checkboxes.

You should take radioButton list insted of checkbox list.
If client select both there is no need to select car or bus.So u can achive this by radiobutton list
Best Regards

I want users to enter only character value into textbox for UserName. I dont allow users to enter any numeric value.
Please help me
|
|
|
|

use the onkeypress function and return false if character code does not fall in alphabets. You can get the code range by alert(event.keyCode()). key code is different for small and capital letters. I think they start from 64 to 92 but I am not sure you can alert them.

Keep a RegularExpression Validator for your TextBox .
For Eg:Add the following line below your text Box in the source View.
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="Enter Only characters" ControlToValidate="YourTextBoxID" ValidationExpression="^[\w]$" />

I have three update panels with conditional updatemode. First paneld containt navigation buttons and dropdownlist for paging. Second panel contains sortable datagrid with and edit/view button in last column and triggers fired by the nagavtion buttons. The third panel contains a form to show the details on clicking the edit/view button in datagrid.
Most of the times all these are working fine. But some time onclicking the navigation buttons (first panel) the whole page flickers. Can someone tell me why?
Secondly whenever I edit any record by clicking on edit/view button, it shows me details fine. But right after that if I sort the grid, the whole page flickers instead of the second panel only. And it happens everytime I sort the grid after clicking on edit button. Second sort works fine?
Thanks in advance.
WELL: I just tested in firefox and it is working just fine in firefox. So I quess it is IE stupid stuff..

My guess would be a) your using IE which has some horrible page flicker bugs in it and b) it occurs because most of the page is being updated (ie more than one panel), for smaller page updates you probably won't notice it. Does sorting the grid also update the third panel? I would of thought so...
|
|
|
|
|
I think your first guess might be true.
Your second is wrong because it is not updating all panels, it only updates the panel which I call panel.update or which have triggers. So updating is working fine only flickering of page is a problem that happens randomly. Most of the time it is working just as expected.
Thanx for your response.

Hello
I started a little web project, where the users can register and make their own sites.
Now i want, that the User can access his personal site directly over the path http://xy/[Username] like many other sites. For example http://www.myspace.com/userX
But I don't know how to make that dynamic? Sure there is a possibility without create a directory, create a virtual directory and put a index file into it, for each user.
Probably it has not a lot to do with c# (I program into ASP.NET with c#). I'm sure someone here can help me?
Thanks for your help
Yours sincerely
