Retrieving checkbox value from db
-
using that code im able to insert the check box value but if i check multiple check box im able to insert only one value to db how ineed to insert for multiple values.. and how do i retrieve that values from db i.e, the check boxes should be checked when i get the values from db.. please help me...
foreach (DataListItem dli in DataList1.Items)
{
CheckBox Chk = (CheckBox)dli.FindControl("CheckBox1");
if (Chk.Checked)
{
SqlConnection SqlCnn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
// SqlDataReader dr;
SqlCommand SqlCmd = new SqlCommand();
SqlCmd.Connection = SqlCnn;
SqlCnn.Open();
SqlCmd.CommandText = "insert into test(test1) values('"+ck.Text+"')";
SqlCmd.ExecuteNonQuery();
SqlCnn.Close();
break;
}
else
{
str13 = "you need to check";
}
}
LblErr.Visible = true;
LblErr.Text = str13;Bigger picture here would help. What exactly do you want to do? Do you wish to save the text for all the check boxes that have been checked? If yes then your code here is not doing it right. Your code is static in nature
SqlCmd.CommandText = "insert into test(test1) values('"+ck.Text+"')"; SqlCmd.ExecuteNonQuery();i.e. every time you get a positive, the query take the text value of the check box and saves it in the db against the same table column. So, what happens is the first positives text get over written by next which again get over written by the next and goes on until the last positive which gets saved ultimately. If you wish to save all the texts to the db, then you have got to concatenate all the text values in one string, inside the foreach loop and use it in the query and execute it outside the loop. HTH!

First things first, tell us how exactly are you creating your check boxes? I mean the what is the source for your checkbox's text?

break;statement will move you out of the loop once First data is inserted. Just for your knowledge, google it and you will find what for break is used. So, remove the break statement from if block then all your checked records will be inserted to the database.Anurag Gandhi.

initially i used a label to check if break is not used i need to check all check boxes for label to true and viceversa
See your variable str13 is not associated to the every item/checkbox in datalist so it will alyas be the latest. Regarding the checkbox, try to debug the the code whether you arre able to access all the checkbox in the datalist and their associated values.If you are able to get the checkbox's value specifically then why they are not getting inserted. One reason I can think of your row might be getting updated everytime so thats you are getting the latest one.Verify it. Also

I don't want to see your code buddy. I want the business case.

im having around 30 checkboxes in page i used datalist to display. when check boxs checked i need to insert their names into one column(seperated by comma or space) then when i get those values from db check boxs need to be checked(edit mode)...
What is the condition that dictates that you need 30 check boxes? Do you create the checkboxes at runtime or are they available at design time itself? I suppose you create them at runtime. If so, from where do you get their names i.e. the text for each checkbox? Are these text values unique?

text of check box is a column from db using datalist.. all values are unique..
If you already have the text in the table, then why do you want to save it again the db? I understand that you need to save the state but why save the text?? What is the relevance of these checkboxes to the rest of the screen? i.e. is the state common across users or each user gets his/her own set of checkboxes? When you save the state to the DB what is the reference that you would be using to retrive it??

all users is having the same textboxes..

Im saving it to a different table so i used text to insert into new table..
Response.Write(ck.Text + "<br/>");
with this i can get multiple checked text values but how do i insert into db. saving state or text whatever it may be i need to retrive them from db but my sir wants text..

Ok I'm not getting why you need to do it this way so here you go. pseudo -
Declare string CheckedBoxesText --- Use a stringbuilder
For each check box in datalist
if Checkbox is checked
Add concatenate checkbox text to CheckedBoxesText
else
do nothing
End of Foreach Loop
Query = "insert into test(test1) values('"CheckedBoxesText"')";
Execute query.Implementing this pseudo would enable you to save the "text" of your check boxes to the db.

Remove the
break;statement from the For each loop. -
