Forms Data Controls :: Checkbox Selection Based On Group Column Values In Gridview?
Jul 28, 2010
I have to select checkboxes besed on group column values. If you see below gridview, column 3 (GroupN) has 1,1,1,1,2,2,2,2....etc (this column data is not static, will change based on page index. i.e PageIndex =2 may starts with 7,7,7,8,8,8,8,8,9,9,9 etc).
Now My question is.
1). If user selected '1', we have to store value and user must and should select another '1' (atleast two times).
2) If user selected '1', and user trying select '2'. Giving error says "Must have select one then one record in group to combine' (will not allow) and unselect '2'.
3) If user selected '1' atleast two times, and user trying select '2'. Will allow.
4) If user selected '1' atleast two times and selected '2' one time, trying to select '3'. will not allow user to select '3'.

Using checkboxes, can the row of record(s) be inserted into a database? I am populating a Gridview. Done. A checkbox field has been added, when the user selects one or more rows, a submit button (which is not working) needs to inserting those records into a table. The insert statment will work outside of the page but is not working using the scenario I jut described. Is this task as I have outlined doable?

I have a gridview which displays following columns:
TaskID, TaskDescription, IsComplete, DateOfCompletion
Now what I want to achieve is, when user clicks IsComplete checkbox, she must enter the date of completion. So, I want a validation (client side) on DateOfCompletion if the checkbox is selected (checked). And, I also want to use Validator Callout Extender
if possible.
How can I achieve this?

I'm having trouble figuring out how to display a gridview based on the selection of a drop down list. I manually entered the drop down list items, but in the configure/choose data source I don't understand how you make a relationship between each list item and the corresponding database table you want to show.

i want to see the sales in the grid view based on the month selected from drop down list. Ex: when I select June 2010 from the ddl box, the sales for that month are correctly displayed in the grid view. I go to page 4 to look at some sales there and then switch the month to August 2010 to see sales for that month instead. Here is the problem. When I switch the month, it show August 2010 sales, but stays in page 4 instead of going back/resetting back to page 1 of August 2010 sales.
How do I reset the grid view page back to the first page of August 2010 sales?

I am trying to retrieve a value from the row based on the user checking the checkbox but the only way it works is opposite of what I think it should be. The problem is I can only get the values if I set "If RowCheckBox.Checked = False" So I have rows returned in the gridview:
row1, record1
row2, record2
row3, record3
I want to check row1 and row3 and grab the values record1 and record3 I use:
Dim str As String
Dim row As GridViewRow
Dim index As Integer = dgrdSearchResults.SelectedIndex
lblStatus.Text = index
For Each row In dgrdSearchResults.Rows
If index = -1 Then
index = 0
End If
Dim RowCheckBox As CheckBox = CType(dgrdSearchResults.Rows(index).FindControl("chkResults"), CheckBox)
If RowCheckBox.Checked Then
str = dgrdSearchResults.Rows(index).Cells(2).Text
lblStatus.text = str
End If
index += 1
Next
With this code I basically step out even when I have rows checked. zaybe I am looking to much but I cannot get it to return the values I need unless I change "If RowCheckBox.Checked " to If RowCheckBox.Checked = "False"

Submit(Button)
When user Click the Submit (Button) the selected dropdownlist and Remarks will be displayed in the Gridview. The Gridview as follows
Dropdown Reason

instead of Select the Good from dropdownlist1, user wrongly select the Poor from the dropdownlist. that time POPUP screen is to displayed.(Only when user select the Poor from the Dropdownlist POUP Screen is to be displayed in that textbox type the reason and click the Submit Button). Then Gridview as follows

I have a gridview object to which I added
<asp:TemplateField >
<ItemTemplate>
<asp:CheckBox ID="chkCopy"
OnCheckedChanged="chkStatus_OnCheckedChanged"
runat="server" />
</ItemTemplate>
</asp:TemplateField>
The page count is set to 10, when the user checks the checkbox(es), I will need to insert those records in a table. How will I know which row was selected? I found an example (untried) that is designed to loop through and insert the necessary records; but it does not address inserting records based on selecting rows via a checkbox. How do I put everything together.
// open connection
mySqlConnection.Open();
//enumerate the items in the list
foreach (SPListItem curItem in curItems)
{
string sql = "INSERT INTO ImportNotifications";
sql += "
(SharepointID,Title,WorkOrderNumber,Status,Department,ClientName,WorkOrderDueDate,CreatedDate,CreatedBy,ModifiedDate,ModifiedBy,Late,LateRe
view,TrueLate,Body)";
sql += " VALUES
(@ID,@Title,@WorkOrderNum,@Status,@Department,@ClientName,@WorkOrderDue,@Created,@Author,@Modified,@Editor,@Late,@LateReview,@TrueLate,@Bod
y)";
mySqlCommand.CommandText = sql;
mySqlCommand.Parameters.Clear();
mySqlCommand.Parameters.Add(new SqlParameter("@ID", SqlDbType.Float)).Value = curItem["ID"];
mySqlCommand.Parameters.Add(new SqlParameter("@Title", SqlDbType.NVarChar, 200)).Value =
curItem["Title"].ToString();
mySqlCommand.Parameters.Add(new SqlParameter("@WorkOrderNum", SqlDbType.NVarChar, 50)).Value =
curItem["Work_x0020_Order_x0020_Number"].ToString();
mySqlCommand.Parameters.Add(new SqlParameter("@Status", SqlDbType.NVarChar, 50)).Value =
curItem["Status"].ToString();
mySqlCommand.Parameters.Add(new SqlParameter("@Department", SqlDbType.NVarChar, 100)).Value =
curItem["Department"].ToString();
mySqlCommand.Parameters.Add(new SqlParameter("@ClientName", SqlDbType.NVarChar, 255)).Value =
curItem["Client_x0020_Name"].ToString();
mySqlCommand.Parameters.Add(new SqlParameter("@WorkOrderDue", SqlDbType.DateTime)).Value =
curItem["Work_x0020_Order_x0020_Due_x0020"];
mySqlCommand.Parameters.Add(new SqlParameter("@Created", SqlDbType.DateTime)).Value = curItem["Created"];
mySqlCommand.Parameters.Add(new SqlParameter("@Author", SqlDbType.NVarChar, 50)).Value =
curItem["Author"].ToString();
mySqlCommand.Parameters.Add(new SqlParameter("@Modified", SqlDbType.DateTime)).Value = curItem["Modified"];
mySqlCommand.Parameters.Add(new SqlParameter("@Editor", SqlDbType.NVarChar, 50)).Value = curItem["Editor"];
mySqlCommand.Parameters.Add(new SqlParameter("@Late", SqlDbType.NVarChar, 50)).Value = curItem["Late"];
mySqlCommand.Parameters.Add(new SqlParameter("@LateReview", SqlDbType.NVarChar, 50)).Value =
curItem["Late_x0020_Review"];
mySqlCommand.Parameters.Add(new SqlParameter("@TrueLate", SqlDbType.NVarChar, 50)).Value = curItem["TrueLate"];

Also, how can i loop through the checkbox items to make sure the conditions are met in order to display the dropdownlist
