update the edit template as below.
<asp:TemplateField HeaderText="Cost Code">
<EditItemTemplate>
<asp:DropDownList ID="ddlCost_Code" runat="server" AutoPostBack="true"
onselectedindexchanged="ddlCost_Code_SelectedIndexChanged"
AppendDataBoundItems="True">
<asp:ListItem Value="0">-Select-</asp:ListItem>
</asp:DropDownList>
<asp:Label ID="lblCostCode_Hd" visible="false" runat="server" Text='<%# Bind("Cost_Code") %>'></asp:Label>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label6" runat="server" Text='<%# Bind("Cost_Code") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
take one hidden label "lblCostCode_Hd" which hold the selected Cost Code. and in row databound add below code.
ddlCost_Code.DataSource = dt_for_CostCode;
ddlCost_Code.DataTextField = "Cost_Code";
ddlCost_Code.DataValueField = "Proposalno";
ddlCost_Code.DataBind();
Label lbl = (Label)e.Row.FindControl("lblCostCode_Hd");
if(lbl != null)
{
ddlCost_Code.Items.FindByText(lbl.Text).Selected = true;
}
so, this will select the particular code which you have selected.
hope it works.

it is working and showing the sected value. but when I change it by selection another item in dropdownlist , it auto select the last selected item itself. this is the main issue
|
|
|
|
|
try by making AutoPostBack = false.

I need selectedindexcahged event for some work, without AutoPostBack = true it is not possible.
So I need to keep this property to true. By the way I tried by making it false but the same result I got, it didn't give the solution
|
|

|

check in any of the events you are rebinding the grid again ?, because rebinding the grid will make the dropdownlist to select the previous value.

after selecting an item from ddlCost_Code selectedindexchaged fires then the whole page posbacks and I am binding the grid on page_load event.
|
|
|
|
|
So, Since you are re-binding the grid, Row_databound is firing, and dropdownlist is also re-binding and the default value is selecting. so, handle the dropdownlist selected index changed evnet, but do not rebind the grid, or else, before binding check the edit index whether edit index is equal to -1 or not. if EditIndex = -1, then bind the grid, otherwise leave as it is.

Hi..I am currently working on a project on Library Management System. I ve created a database to store the books in the Library. While adding books, i want to add multiple copies of the same book. i need to create a unique book ID for each book..how can i make multiple entries of the same book wid different IDs for each?
eg., Book name: Engineering Thermodynamics
Author: P K Nag
Publisher: ABC
Edition: 2
Category: Mechanical Engineering
Quantity: 5
i need to add this data to the database making 5 different entries for the same book wid a unique ID. Plz help me!
|
|
|
|
|
You need two tables, one describing the book, and one for each copy. The latter references the former, using the ID of the book description table as a foreign key.

There is a limit on the max length of a JSON returned, you can adjust it in the web.config
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="50000000"/>
</webServices>
</scripting>
</system.web.extensions>
As for the reason for the super long JSON returned,
In my opinion, I would of created a web service, called test.asmx, and return a formatted JSON result, and then parsed it. But what do I know, I have no clue what your trying to do.

hopefully i am posting in the correct section.
I have created a class in c# to replace a vb6 class used in an asp web page. Note I said asp and not asp.NET. I am running this in IIS 7.5 on a 64 bit Windows 7 machine.
I compiled the program and all its support dlls as x86 and believe I got all the correct tags and check boxes for COM. I can create and use the class in VB6 but it still bombs in vbscript with can't create object. I found some articles on going to do tweaks in the registry to get it to work on 64 bit but alas no avail.
The web application will run with the old VB6 object just fine. The configuration is an application with a separate pool set to pipeline mode classic, no managed code, enable 32 bit applications = true;
Initially I was getting a can not create object when trying to use the new c# object but I copied the dll and its support dlls to the sysWOW64 directory and it changed it's tune to
MaxRecall.Shared error '80004003'
Object reference not set to an instance of an object.
/mr/mrq.asp, line 193
the structure of the project is thus
the object I am creating with createobject is dependent on a single assembly, MaxRecall.CORE, which is dependent on two assemblies, MaxRecall.CLIENTS and MaxRecall.Shared. None of the support assemblies are com exposed so this error is not a COM error at all I think.
MaxRecall.Shared is totally static with zero objects to create. It only had two static doubles that were class scoped that were not instantiated but I set them to 0 in their declarations. To my thinking there are no objects in MaxRecall.Shared to gain an instance to so the error is odd.
Sigh. Any and all insights are desperately welcomed. I cross posted this in the COM section.

Article with code and sample were shared. If you are unable to understand it, it would be difficult for me to make you understand online. I would suggest you to catch someone in person - a senior or a teacher.
