Forms Data Controls :: Accessing A Cell In A Inserted Row?
Jan 25, 2010
I have gridview, and in this gridview, I insert a new row dynamically depending upon a value from the database all the way down the table. Even though this is all working well, I need to access a number of controls that I added to the inserted row. Namely, a checkbox and label. When I try to access these controls, I am getting an error message - object not set to reference. Then I tried saying "Gridview1.Rows[rowIndexVal].Cells[1].Text = myTextVal", but what this does is to insert the value on a different row.
Therefore, I have two problems, which I am really desparate to try and solve:How do I access the correct row and control that I have added to my inserted row, andBecause I have a checkbox control on my inserted row, which has an event associated with it, how do I get the selected row the user clicked. When I try doing this using FindControl, I always get a row index of zero.I am using Table object and TableCell to add a new row dynamically to the gridview, and then using ColumnSpan to make it fit the number of columns in the gridview.
In my application Iam using GridView, in this there are fields (Quantity, Price, Amount) the user can enter Quantity Field value which is a template field (textbox). Iam calculating Amount(Quantity * Price) using Javascript and assigning to the Amount Column cells as below
Gridviewcell.innerText=Quanity * price.
and when user clicks on the Save button I want to add these details of Gridview to the database.
when I try to access the values of the gridview using below code
For i=0 to GridView.rows.count-1
GridView.Rows(i).Cells(2).toString ( for Example)
Next i
It is not displaying the changed value instead it is displaying the default value before calculating the amount.
Before implementing the Javascript part, I had done this in the code behind and it was working fine... Now I just dont want the page to get load so I used javascript.
able to access the value of Gridview cells which are assigned using Javascript.
I have a grid view populated with some data included bit fields and I made an export to excel function For each row i need to check the cell with the bit value to change the cell color, but the cell is always empty, even if is the field is set to False or True. foreach (GridViewRow row in gv.Rows)
I'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.
[code]....
I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
Datagrid is in content,When trying to access client side function for the cells in the datagrid,its always showing at 0 position suppose i have 10 rows,for each row "Test button" i should invoke the client side java script. For each row "Test button" client side script is displaying message at first row only.
in datagrid i am binding the description and button to every row in datagrid
so i have added Testbutton.attributes.add("onclick","return javascriptfunction();"); in datagrid_itembound.Iam showing one div in client side function but that is working only for one row,when iam trying to click test button in second row,itsshowing that div in first row instead of second row
i want similar functunality like displaying of flag button in stackoverflow.
I have a SQL 2005 database table with a column that has a datatype of nvarchar(255). It holds URLs.I created a FormView to edit records in the SQL table. The value for this column gets put in a TextBox in the FormView.When trying to edit the record, any text placed in the textbox gets truncated at 50 charactersI checked the TableAdapter in my dataset, and in the properties for that column, it has "255" for MaxLength.
I'm trying make FormView insert a new row into a database table via a stored procedure.My code runs without error but nothing appears in the database table.
I am working with GridView, When huge amount of Data is inserted in the GridView its columns became very thin all tall, however I want to Display the Gridview with Fix size and if the Data is hugeit only display the starting few words of Data.in other words I want to use gridView same like the GMAIL account where Data Display like this. .
I've been pickling my brain trying to do this for a couple of days but to no avail. I have the following in "FormView1" which I'm just using in insert mode:
I'd like the contents (i.e. whatever the user wants to insert) to be passed to a method where it will be checked against any existing values in the database.
I am using a Listview with InsertItemTemplate bound to a LinqDataSource with a child table in the ORM datacontext. This table has a relationship with a parent table in the OR/M datacontext. The record is to be inserted in the child Table. The parent table is bound to dropDownList in the InsertItemTemplate to provide a user friendly name. Using the ListView ItemInserted event in debug, I can follow the execution and no errors occur BUT no record is inserted. I confirm this by a showing all Table Data in the SQL Mgmnt Studio. The child to parent table seems to be causing the problem because when I delete the relationship in the OR/M .dbml , I am ABLE to insert records. I am using Scott Mitchells' Using ASP.net 3.5 ListView with Data Pager controls: Inserting Data as a model. I can provide code if required, but what is going on with the deleting of the relationship between child and Parent.
I'm coding with VB.NET and have a webform that includes gridview. The gridview captures data via a db view. Also the view includes all the parameters of the tables.
The problem is: when start program, there is only 2 rows seen on gridview. then i can insert something successfully. And when i checked from db i can see the new data. But in my form, newly inserted data doesn't seen. Even i restart the whole program, gridview always shows only 2 entries.
I am currently binding my Detailsview and Gridview together by a "ID" field selectedvalue "1". Which works great except for the fact that I don't want the user to have to go down to the gridview and select the page and then the record to view it in the detailsview.
I have 1 sqldatasource for detailsview and another sqldatasoure for the gridview. Both have the exact same select statement.
I want the gridview and detailsview to automatically display the last record inserted not the first record in the table.
This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.
after a DetailsView (DV) 'Insert' (triggered by a DropDownList (DDL)) the DV shows the first record (in the DDL)!Are there VS2008 means to keep / show the just entered data - again ready with the command row "Edit/Delete/New" enabling me to e.g. "Edit" the just entered data?This DDL/DV scenario works just fine but to show my just entered record I have to leave this page and start calling this .aspx page again in order to see the name in the DDL and, hence, in the DV.I.e. I'm looking for a kind of automatic 'postback' bringing my just entered data back
I have an object data source control. and to insert the control I add the object to the database then call databing on the gridview the DataSource control is bound to.
My question is - how would I know where the newly added row is? I can'y go by id, because the dbase creates the id.
I'm thinking maybe last data key, but based on the sort that would be accurate.
In my mysql I have an autoincrement id , whenever I add a new row into database I need to store this id in other table, so how to get this autoincrement Id back?
I have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminsertedevent?
I'm needing to get the selected rows, based on checkboxes, to insert into a different table than that that the gridview is formed from. I've created an innerjoin datasource to try and solve this but, still having problems finding something that works. I also need it to insert based upon a button click not inside the gridview as I believe otherwise would only hamper the situation more.
I want to be able to show the record that was just inserted after add_button_click event. I run the insert from mycommand and then set mycommand2 to run the read to populate a details view. I have a feeling I am going about this the wrong way. The insert fires correctly but the details view does not populate.
I have a repeater control and a text box, and likewise a button to post data to database.after i insert the data to the database in thwe click event of the button, the datalist will not update the displayed content. at the end of the button's click even, i added the code line:
Response.Redirect(Request.RawUrl)
But still, the datalist will not update automatically. What do I do next?
