Forms Data Controls :: Writing To A Grid One Row At A Time?
Feb 19, 2010
I would like to read from a data reader (or other) and write to a grid of some kind one row at a time in a loop. I prefer this rather than load a data bound grid control all at once. I need to do this because I have to perform some calculations on the data before writing each row.
My problem is that I have a grid view that show the data from database.In my gridview i add a column name date .like eg You knw that when we send a scrap to anyone then show time how much time to send a scrap.
I need to know that how i can edit the particular cell value in grid view at run time just by clicking it(value) then it shows text box and after enter any value, it then save in database.
my problem is that i have a gridview that fetch the data from database .I added the linkbutton on gridview that redirect to next page but cant working becouse at run time i add a bound field on gridview to calculate the time. source code
i created a user control and place a button on it.i drag dropped the user control on a aspx page and wrote the grid load and button clicks in the
user control.now i got a requirement to use the same user control grid and button to again use on the same page.however the data populated will be different and the button click functionality will be different.how can i reload the different data on the second grid as i had already wrote the code in the first one
Have a GridView with a templated select button hidden and using
e.Row.Attributes.Add("onclick",Page.ClientScript.GetPostBackEventReference(this.grdMaster, "Select$" + e.Row.RowIndex.ToString())); to select a row .
When user like to update the datasource he will select one row from gridview then in selected indexchanged event i would display the selected row values beneath the form under the grid , Then user will update the contents displayed from grid and click an update button which is outside the grid . After updating the displayed row , i got to get the values of the next row in the grid and display them for next updation , i'e if users maually selects row 3 from grid then he can update the values using the update button and then on update click itself i'll have to display next row contents of row 4 and this process could go on .
I have Parent/Child Grid (also called Nested Grids).
Parent Grid (PG) :: PG has two template fields. 1st template field has "Category ID" and 2nd template has Child Grid
Child Grid (CG) :: CG is populated in PG's RowDataBund event based on "Category ID". In CG's DataBound event, I am doing something which I need to display in CG's footer row.
Problem :: In the footer row of each CG, I have to show the "Category ID" which is in PG' row. How can I get hold of the PG's row which hascurrent nested grid (there will 'n' child grids, one for each 'Category ID' in the PG ) so I can read the "Category ID"
I was thinking if I could do something (DataBound event of CG) like this..
string catId = ChildGrid.Parent[get the index of the current row in PG].Cells[0].Text;
I am trying to create a second grid in the same page with detailed info for a given record of the first Grid, but when I press select in the first grid nothing happens. I follwed everything I read.
I have a grid view that does add, edit update and delete. ( I draged the grid to the aspx page ) it is working. I would like to have the following : once I lick on edit, I open a form inside the grid view to edit the fields. How can I do that.
I'm using ASP.NET/VB and am wanting to nest a grid inside of another grid. I've seen them but am unsure how to make them work. I have a Orders table with an OrderID and it is linked to a Orders_Detail table. I would like to be able to select the order and see the details. I've done it differently with 2 grids outside of each other, but this isn't the solution I need.
Im trying to make a web chat using ajax control tool kit. There is a script mannager, the update panel and the timer. I inserted the textbox for showing every text that is introduced by the users, the text for writing and the send button are out. It works great but if im writing some text in the exact moment of refreshing time (winch happends a lot because its every 3 sec) it does not let me write correctly cause the textbox kind of blink and you miss a letter. So, wich is the correct method for doing this without lossing the fluidity of the writing.
I want to write "upload multiple files at a time" functionality during upload files in dot net.I am not allowed to use JQuery.All i want is core dotnet.
how to suppress the "AM" in the gridview (template Bind("RideTimeMin", "{0:t}")? Don't tell me to use military time because the function is not "time on a clock"; it's how much time is allowed for a task (in this case the min/max hours & minutes that horses have to complete a 20 mile trail; e.g. 05:00, 05:27, etc). I'm currently accomplishing this in the "ondatabound" function by "..RTmin.Replace("AM","")". I have looked and looked at all the websites that talk about datetime formatting but have yet to find a way to do it upfront in the gridview bind statement.
I've got an asp.net application (written in vb.net). I have a results page that spits out some calculations. Ineed to write out that output to MS Word. The catch is, this happens within a folder that is secured (only users that are logged in can generate the word document).
Here's what I'm using to gen the document. This works ok when running it locally, but not when loaded to GoDaddy hosting.
[Code]....
My code seems works fine locally. However, after loading it to GoDaddy it only works on a non-secured (not subject to ASP Membership), but when trying to use it in a secured folder the page clocks and eventually closes out.
i just cannot work this out... i have a gridview and when a user clicks on a row the checkbox unchecks itself... when the user clicks the row a sqldatasource.update is called from the selectedindexchanged event, problem is when it writes back to the database it writes back every checkbox as unchecked, i want just the row that's selected...
what i can't work out is i've tried putting a where clause in the sqlcommand which is something like where primarykeyID = gridview1.selectedvalue... now it won't write anything back to the database...!!! ... once i take out the where clause, it writes back to every row..!!
I'm writing an asp.net site in vs2005 asp.net c#, I'm using google charts api and found a lot of disadvantages. Which tools do you use and recommend? I need charts, pies, bars and data presentation, even payed systems can be considered(<200$ per server). I used in the past the buid in reports viewer which has a lot of bugs.
I have a date/time stored in a smalldatetime field (ms sql 2005) that i want to compare with the current time and receive a difference. If the difference is less than 30 minutes, do this....if more do that....
This is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)
If IsDate(pasDate) Then Try If pasDate <= System.DateTime.MinValue Then Return Nothing Else Return CType(pasDate, DateTime) End If Catch ex As NullReferenceException Return Nothing End Try Else Return Nothing End If End Function
So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".
I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.
IS THERE A BETTER WAY TO UPDATE/INSERT TIME FIELDS.
