Forms Data Controls :: Column Not Updating On Click?
Apr 22, 2010
I am using a gridview to show data in a formview on a ModalPopup. in the modal I have a Close button and Delete button. The delete button has a click even that is supposed to updated a column in the table, but it doesn't and I can't figure out why.
[Code]....
The varTransactionID variable gets value upon click of the gridview linkbutton so the value should be there. As you can see I have tried 2 ways of adding the Parameter Value of @TransactionID, they both do not work. The column never gets updated. [explanation] The reason why I do not just delete the record is that as Web Admin I want to still be able to view what changes are made to accounts so I can adjust the site to make things more user friendly, the user may not see the "deleted" record, but I still can.
I'm trying to implement row editing on a gridview using a SQLDataSource, the updating works fine for all values in the row except for on value, Clock Reset Time. I have tried all sorts, tried converting to template fields, tried reordering columns, changing update query etc. I just cannot get the gridview to update the Clock Reset Time. here is the code.
I have a gridview in which update and delete is enabled.
I have the following fields in database table, which is binded to the grid view through sql datasource.
ID,Firstname,Lastname,Add,City,modifieddate. Here ID is primary key.
1. When edit and delete is enabled in the grid. The ID column is showing in the grid,which i don't want to show. But without that ID column the grid is not able to update and delete. Plz tel me how to update and delete without ID column in grid.
2. When ever any update is happen in the grid, the modifieddate should get updated. Here the date is not datetime.now , i need to use my own system date and time. Coz my server and system time has some difference.
I have use the following javascript to get system date and time, which is working fine. This date should be get and update in the modified column.
function displayTime() { var m_names = new Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"); var localTime = new Date(); var year = localTime.getYear(); var month = localTime.getMonth() + 1; var date = localTime.getDate(); var hours = localTime.getHours(); var minutes = localTime.getMinutes(); var seconds = localTime.getSeconds(); var div = document.getElementById("TextBox1"); div.innerText = date + "-" + m_names[month] + "-" + year; }
I have been struggling with this problem for a long time. Does anyone have any clue about this problem? I created a gridview and set the allowsorting to true. This gridview has four columns: Name, Position, StartDate, and EndDate. I want the gridview to be sorted on the EndDate.
Inside of the save event, I called the BindGrid() function to rebind the datasource to the gridview. The changes will shown immediately, but the problem is that the records are not sorting on EndDate. I have to refresh the page manually to get the view sorted.
In trying to improve 'user experience' with a GridView, I have an administrative application where a GridView is displaying records from a SQL table. One of the columns is a bit column, and is displayed as a checkbox in the GridView. I want the user to be able to simply check or uncheck the box while viewing the GridView, and the value in that column for that record is immediately updated. So I set AutoPostBack="true" on the CheckBox in the GridView's Template Field.
But tests are indicating that the column value is not actually getting changed, even though the page appears to post back and displays the newly checked (or unchecked) checkbox correctly. But if I check the SQL table directly the column's value has not changed.
I created a gridview that is bound with an SQL datasource - I added a gridview button column. I need to update/insert 'Y' on a specific cell in the row when I press the button
This is my gridview code
[code]....
The button column I have says delete on it but it shouldn't really delete it - Once I press the button it puts a 'Y' on a column that is filtered out by my sql statement in the sql datasource
I have a gridview with checkbox. I have this code on a RowDataBound Event
If e.Row.RowType = DataControlRowType.DataRow Then e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString)) [code]....
But the problem now is everytime I click the checkboxes I am redirected to a page because I have a Response.Redirect in SelectedIndexChanged event. How can I be able select a checkboxes and redicrect only when I click in a certain column.
Scenario: I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is: I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I have a requirement as mentioned below: 1. There is a gridview containing a linkbutton field (lnkgdvMerchant)in one of the column defination as menioned in the mark up below :Please note the bolded line of code for more details.
I have a page with a TextBox, a Button, a GridView, and a SqlDataSource. I click the Button to execute the SQL in the TextBox using the SqlDataSource. The SqlDataSource populates the GridView. Everything works as expected until I click a column heading to sort.
When I click a column heading, the GridView disappears and I have to click the Button to display the grid again. When I do, the grid is displayed in the order of the column I clicked.
I don't understand why the GridView is disappearing when I click a column header.
Does anyone know how to fix this so the GridView is sorted and displayed only by clicking the column header?
I have several grid views indide div's, and when I click the Sort header on an open div the div collapses and no sort happens. I believe it is just reloading the entire page but when I surround PageLoad with !ISPostBack then the page redraws as blank. Since the sort script is generated by the GV, I don't know how to stop it from creating side effects.
Here's my code:
<script type="text/javascript" language="javascript"> function toggleDisplay(id) { var obj = document.getElementById(id); obj.style.display = (obj.style.display == "none") ? "" : "none"; return false; // cancel the href } </script>
If the grid column is clicked to sort i dont want to retireve data agian, i can get it from viewstate, but i dont know if that triggered the post back or if the ImageButton on the page triggered it
I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.
I have a DataGrid with a TemplateColumn containing an asp:DropDownList and a BoundColumn. I'd like to have a VB.NET handler for when the selected item in the DropDownList changes. I'd like this handler to also update the value in the BoundColumn with the value of the newly selected item in the DropDownList.
Can someone point me to some resources I can examine to learn how to do this?
If the handler for the selection changing can give me the value of the NEWLY selected item, it should just be a matter of accessing the cell for my BoundColumn in the same row and writing to it. I do not know the syntax to achieve this.
I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.
I am looking to sort a column on my gridview by simply clicking on the column rather than clicking on the column header. In the design I have been given, the column header will not be shown, and I need to be able to give the user to sort this column, by simply just clicking any where on the column.
when i am in ItemTemplate all the column (7 column) are label so it fit to the current screen
by when i use EditItemTemplate or InsertItemTemplate the coulmn don't fit the the current screen and
i have to use the ruler in order to see more information about the cell (which is ok - because in each cell i have a dropdownlist or long textbox)
but when i drag the ruler to the right size to see more information only the cells are moved but the header coulmn stay so i see the current coulmn with worng header coulmn
I'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.
