Here is the link that will help you out:

Just change the query to insert/update/delete based on your need.

It would be same as you would delete any other record from the database. A quick google search should reveal it.

Can you clearer? It's really difficult to understand what you are trying to ask right now.
like: Where from column came into question when talking of textbox? What do you mean by, field in textbox should come like popup in textbox from database?
Elaborate a little and tell where DB comes into picture and what exactly needs to be displayed in the popup?

My method adds parameters to stored procedure as:
public void AddParameter(string StrName, SqlDbType objType, ParameterDirection objDirection)
{
SqlParameter l_Param = new SqlParameter();
l_Param.ParameterName = StrName;
l_Param.SqlDbType = objType;
l_Param.Direction = objDirection;
Command.Parameters.Add(l_Param);
}
public void AddParameter(string strName, SqlDbType objType, ParameterDirection objDirection, object objValue)
{
AddParameter(strName, objType, objDirection);
}
I have send parameters to stored procedure using above method and used ExecuteScaler and ExecuteReader both. But it displays error while executing stored procedure.

What is the error message?

Looks like you forgot to add:l_Param.Value
Add:
l_Param.Value = objValue;
You shouldn't be needing the other AddParameter method. All can be done in one.

For Parameter type Input it works perfectly. But with OUTPUT Parameter Type It Displays following Error in place of ExecuteScaler Method:
String[1]: the Size property has an invalid size of 0.
(Actually I have a Stored Procedure which takes @Amount as input and converts the input in word, here @word in output Parameter. It should convert input amount in word.
Stored Procedure is right. but something wrong with executing from application.
What should i do.

As per your error message , you should mention the size of outout value (irrespective of in or string whatever your output type). please give a try and let me know.
As an example: if you are exptecting to get "cheers" as a word that appears from @output valiable, then mention "6" as the size of the output parameter along with itoutput parameters type.Thanks,

Stored Procedure is executed after specifying the size of output parameter. I unable to get output parameters value as:
string s=ExecuteScaler(cmd);
Parameters value is not retrived in s. But if i cal using
com_parameters[strParameter].value it gives value. I mean it gives single row data.
How can i get OutPut parameters and other datas in tebular form, Like data returned by Select querry.

please help me with
this......
i am trying to read more than 100000 record from my SQLite database very fast.
At the moment it takes 40-45 second to perform a select on the last record.
Does anybody knows the code for vb.net compact framework, to perform this search in less than 5 or 10 seconds?  al hajjaj

It's not question of the .net code, it's a question of how the data is structured and queried. Are you trying to use any complex joins? Do you have covering indexes? Do you really need to retrieve all 100000 at once? This seems extremely excessive for a mobile application.

Hello, This is Vikash Gohil.
I have a problem related to Gridview as mentioned below.
I have a gridview page that displays All data from a table on page load.
Now I have also provided Data Filtering options on the same page for filtering data that is displayed.
Now when the user provides a filter condition, gridview only displays the filtered data.
But once the user clicks on Next or Previous in the Gridview pager, the filter gets removed and the grid again displays all the data.
What I want is the filter condition should remain until the user provides another condition for filtering.
How can I go about doing this.
Anyone can give me some idea.
This would be of great help.
Awaiting a reply, Thanks in Advance.
