Error :--System.Data.Common.DataRecordInternal.get_Item(System.String) - ASP.NET Discussion Boards

Thanks Alexei,

Image that when I tried to deploy another version of application, which the email content(physical file) used by application has been updated, but the code still reads old value from cache instend of the new email file because cache("key") is not Nothing.

Im not sure if you can use this in 1.1

Take a look at CacheDependency
Add you email file as a cachedependency
Ass soon as you change that file, the cache item will be removed from the cache

Hi, iam developing recruitment application for my client , my problem is that my client inputs all questions in excel sheet and then upload it to database which is mysql , the questions contains some special characters like alpha, beta, gama ,superscript, subscript how can i store these formats in mysql db and the format which is stored should be shown same to the students who are giving exams

When saving some special chars in SQL one needs to use a nvarchar instead of varchar datatype

There must be some datatype in mysql that can hold unicode chars

Dear All

I have a dropdownlist called ddlProduct (it will be fill by productName from product table)

I have two button called btnADD, btnFinish

First time : when you click the btnAdd then will fill a grid view called gvProduct (without adding data into database)
Second time: when you click the btnAdd then it will fill a grid view called gvProduct (without adding data into database)
trird time...........
.
.
.

Last Time

Now I will click btnFinish
when i click btnFinish then it will insert all data into OrderDetails (database table)

The project I want to do is simillar to OrderPlacement like Customer can select Product name from the DropDownList when customer click Add button
then it will shows on the right panel (customer will add more that 5 product) what he added into his basket including price

When he click submit then all data will be added into database and order will be placed

Any instructions will be really helpful

Hi,
How to display images dynamically? am displaying Radio buttons dynamically.My requirement is beside each radio button I want to show image. Am reading data from Xml file and make it in Dataset then using DataView am reading one by one. pls see the code what I have written:

DataSet dsPaymentMethod = new DataSet();
dsPaymentMethod.ReadXml(strFilePath);
DataView dvForDisplay = dsPaymentMethods.Tables[0].DefaultView;

for (int i = 0; i < dvForDisplay.Count; i++)
{
rdb = new HtmlInputRadioButton();
img = new Bitmap(5, 5);
rdb.ID = dvForDisplay[i]["RadioButtonId"].ToString();
rdb.Value = dvForDisplay[i]["PaymentGateway"].ToString();
img = System.Drawing.Image.FromFile(@"D:\VSSNew\SourceCode\Telefonica.MSNOut\Telefonica.MSNOut.UI\images\logos\cards\visa.gif");
panelInternational.Controls.Add(rdb);

}

I have written above code. but it only showing Radio buttons not images. How can I display images? Is there any server side contorl equal to this html ;

Thanks

set text property of radio button to html code like " "

Maybe take a look at <asp:image>[^] ??

Hi,

Using MS.Net 1.1, I am developing a form to display fields into DataList.
Datalist has itemtemplate and Requirefiled validator and textbox & label.

Each field has associated with control e.g.Textbox with in Datalist.

There two enviroment ,Development and Testging.

In Testing Enviroment,Datalist displays fileds sometimes in currect order while othertimes in reverse of previous like First time-
Name <textbox&gt>
Sname <textbox>
Age <textbox>

While other time

Age <textbox>
Sname <textbox>
Name <textbox>
I am not using paging or sorting.with Repeat Direction=Horiz and Repeatcolumn =1

In Development enviroment it is fine.

Where could be the problem?
Thanks.

I would use an order by, you must want them in some sort of order
The order by clause should sort your problem anyway
