using (OleDbCommand command = new OleDbCommand(query, connection))
in dis line

Try This:
<big>string query ;</big>
if(DropDownList1.SelectedItem.ToString()=="ALL")
{
string query = "select * from appointment where DATE > @StartDate and DATE < @EndDate ";
}
else
{
string query = "select * from appointment where DATE > @StartDate and DATE < @EndDate and DOCTOR_NAME='"+DropDownList1.SelectedItem.ToString()+"'";
}

I think it's because you are declaring the string variable, query, inside the If statement, therefore it is out of scope. Declare the variable at the top with the other declarations.
|
|
|
|
|
So how come you're smarty enough to use params for StartDate and EndDate but not for the doctor name?

Hi,
I have a gridview with autogenerated fields, 2 template fields, 1 command field. Now, I want to hide one of the columns in a gridview .
I have a code written in rowdatabound
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
e.Row.Cells[2].Visible = false;
}
this code works well when I have not introduced allow paging=true.
but when I have a page indexing property my code for pageindexingchanging is:
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gridview1.pageindex=e.newpageindex;
fillgrid();
}
where fillgrid is a function which is simply binding data coming from data base in gridview.
when I add page indexing to my gridview I get an error: 
Specified argument was out of the range of valid values.
Parameter name: index
on this line: 
e.Row.Cells[2].Visible = false;
any help shall be appreciated.

Instead of
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
e.Row.Cells[2].Visible = false;
}
try
protected void GridView1_DataBound(object sender, EventArgs e)
{
e.Row.Cells[2].Visible = false;
}

Hi Meetu,

}
I tried but there is an error that it cannot access 'row' in the gridview1_databound event
|
|

|

Oh Sorry I posted Wrong Code.
Try This
protected void GridView1_DataBound(object sender, EventArgs e)<br />
{<br />
GridView1.Columns[0].Visible = false;<br />
}

Hi,
shouldn't the tags be named <fieldname> and <fieldvalue>? The server is throwing an error because you didn't set the arrays correctly.

Hi Sebastian,
i have set all the array Correctly like
object[] _fieldNames = new object[11];
object[] _fieldValues = new object[11];
_fieldNames[0] = "Set";
_fieldValues[0] = 1;
Output = call.Ex("A", _fieldNames, _fieldValues);
Can u tell me where i am wrong
thanks

Well it seems that the client "call" you are using doesn't generate the correct soap-request. Look at the wsdl of the webservice and compare if the soap-request matches the wsdl. If not, the problem is the "call" object. How did you created it?

Hi,
I want to search a database for some documents and then present the search results from my web application.
I thought about using a GridView but that will display strictly in columns/rows. What I want is to display several rows for each result like this:
----------------------------------------------
Search Result #1
This is a bit of text describing the document
This is the actual URL of the document
Search Result #2
This is a bit of text describing the document
This is the actual URL of the document
etc.
-----------------------------------------------
Can anyone suggest a good approach? I can't use GridView for this and TextArea won't work either will it? Any other ideas?

Maybe a Repeater control?

You may have a look at Repeater [^]control.

in your case try to create a stored procedure attach it with crystal report and make sure that stored prcedure accept parametors..
pass parametors from C# or vb to crystal report in order to filter or display data what every you want..

Hi.. I am using the following code for my remoting example.
When I use MarshalByRefObject it works fine.
using System;<br />
<br />
namespace ns_application<br />
{<br />
namespace ns_authentication<br />
{<br />
public class cls_registeruser : MarshalByRefObject<br />
{<br />
private string _username;<br />
<br />
public cls_registeruser(string username)<br />
{<br />
_username = username;<br />
Console.WriteLine("Registered User :" + _username);<br />
}<br />
<br />
public cls_registeruser()<br />
{<br />
_username = "NULL";<br />
Console.WriteLine("Username is " + _username);<br />
}<br />
~cls_registeruser()<br />
{<br />
Console.WriteLine("User deleted" + _username);<br />
}<br />
<br />
public string username<br />
{<br />
get{return _username;}<br />
}<br />
}<br />
}<br />
}
But when I try to use [Serializable] it shows error "Trying to create a proxy to an unbound type".
<br />
using System;<br />
<br />
namespace ns_application<br />
{<br />
namespace ns_authentication<br />
{<br />
[Serializable]<br />
public class cls_registeruser<br />
{<br />
private string _username;<br />
<br />
public cls_registeruser(string username)<br />
{<br />
_username = username;<br />
Console.WriteLine("Registered User :" + _username);<br />
}<br />
<br />
public cls_registeruser()<br />
{<br />
_username = "NULL";<br />
Console.WriteLine("Username is " + _username);<br />
}<br />
~cls_registeruser()<br />
{<br />
Console.WriteLine("User deleted" + _username);<br />
}<br />
<br />
public string username<br />
{<br />
get{return _username;}<br />
}<br />
}<br />
}<br />
}<br />
As far as I know :
"MarshalByRefObject" will give me a reference to an object created on the server. All the execution will take place on the server.
"Serializable" will send to me the object state, and the execution will be done at the client machine itself.
But at some places I see the following usage :
<br />
[Serializable]<br />
public class_name : MarshalByRefObject<br />
What does this mean?
Also, if [Serializable] is there, what is the use of "ISerializable" interface.
Waiting for responses guyz... I have googled a lot already but am not getting a clear picture.

is it anyhow related to ASP.NET
|

Yes it is .. unless there is a specific message board for .net remoting .
