I have a standard gridview, populated via a SQLDataSource, with columns converted to templates.
The edit templates have text boxes. When saving edited data via these text boxes, I need to trim the values to remove any spaces.
How do you recommend doing so? I've tried various methods but none seem to work.
Currently my update parameters are specified in the SQLDataSource.
I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).
I am using a gridview populated via a SQLDataSource. When editing or inserting data via the gridview, how do I trim the values before they are inserted to or updated in the database? I want to ensure that no spaces are accidentally added to the end of my text values.

I am using this command to trim a cell value from a grid view.
row.Cells[i].Text.Trim().Length
The result return is always 6.
I have checked that the value of this is empty, when I display it on page using this code,
Response.Write(" '" + row.Cells[i].Text.Trim()+ "'<BR>");
I get ' ', it seems like there is a space in it.
Is this even possible? I'm trying to pass the DataKeyName (Primary Key) of my master gridview to an embedded child gridview, using a select controlparameter of the SQLDataSource control.

I have a GridView with drop down boxes that are always in edit mode, and what I want to do is when the user sets a value in one of the drop downs I want to set the value in all of the drop downs BELOW that one (if they are not currently set) to the same value. However, the RowEditing and RowUpdating events never fire because techncially I'm not editing or updating the row.
Here is what I'm wanting to do, something along these lines:

how to place newly added or edited row at the top in the gridview
View 3 RepliesI have a dinamically gridview, populated according with the SQL sintaxe from the user, with a TextBox. I enable in the gridview an Edit button, and the rowEdit works well when fired. But my problem is Update button. How to save the record edited, in a dinamically gridview, when I can't programatically set the fields to be saved? Ie, I need to iterating with all fields in the gridview edited record and update. How to do this?
View 4 RepliesI have a GridView control connected to a SQL database via an sqldatasource. I want to load the contents of a row being edited into an HTML editor when the edit button is clicked.

View 6 RepliesI have 3 textboxes , 1 dropdown , 1 Button and 1 gridview .
Textboxes ID are :ACode , ADesc , ASeq
DropDown ID is :CPhase
Button ID is :AddRowBTN
GridView ID is :PhasesTempGrid
Now whats the story is ?After adding some data into textboxes , when a user clicks ADDRow BTN , that data gets saved into datatable , then that datatable gets binded to gridview and it shows my textboxes data in it .
What i want to achieve ?In my gridview i am use templateField and inside that template field there are textboxes ( Let the users edit the row without clicking any button ) .
Take an example of dummy data and problem persisting in there :for e.g i put some data in textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"Then i click Add BTN , it saves the data in datatable and show in gridview , now if i do this in gridview :ACode = "Edited ABCD"ADesc = "Edited EFGH too"ASeq = "WoW There"Then i click Add BTN , it removes the edited record in gridview and shows original data which had came earlier from textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"I don't want that to be done ... Simple is that user can enter data from textboxes , click the btn to submit into grid then he can edit the data like he want ... data must not get flashed , here's my coding i have done so far :
public void AddNewData()
{
var dt = new DataTable();
if (ViewState["myDatatable"] != null)
{
dt = (DataTable) ViewState["myDatatable"];
}
[CODE]...
here i havent added dropdown combo in gridview but you can do it so that it will save my time (Bind it just the way PhaseDropDown have bind)...
I want to print gridview data but don't want print all data. I want to print only Item Templete Data.

I have a grid view in which when i enter values and press submit button , all the values were shown on the grid . I want to edit the row and after that updated it.
I have used RowEditing function but when i click on the edit button it appears to be blank page means that row editing function not called.
Is there an easy way to trim values in a details view during edit mode? I tried modifying the database query to trim the values, but it didn't like to do both ways databinding after that. I tried looking through all the properties of the text boxes themselves and found nothing. I know I could add an event handler for the databound event, and set all of the values one by one, but this is an application that has existed since before my employment and there are over 40 values in this details view, all in text boxes with seemingly random names that have little to do with the values they represent or obvious naming scheme.
I thought maybe there was a way to way to iterate over the DetailsView.Fields property, but couldn't figure anything out there either. I am not allowed to change the schema from CHAR to VARCHAR either. Any other quick ideas? There is a strong likelihood this page will change again, and I would like something that might take care of this problem for any new fields added in the future without extra work. Unfortunately, redesigning it is not anywhere near a top priority right now, so a quick fix to alleviate some of the headache of using this monstrosity is all I am looking for.
I am unable to get it done as i have huge data in my table which is spoiling the standard look and feel of grid view..
if (row.RowType == DataControlRowType.DataRow) {
ViewState["description"] = e.Row.Cells[10].Text;
if (e.Row.Cells[10].Text.Length >= 25){
e.Row.Cells[10].Text = e.Row.Cells[10].Text.Substring(0, 30) + "...";
e.Row.Cells[10].ToolTip = ViewState["description"].ToString();} }
I have a LinkButton that is databound to a description. Sometimes the descriptions are very long and unorganized so I would like it to show for example 75 characters and then append a '...' to the end of any description greater than 75 characters. I found this snippet which pretty much is exactly what I want to do :

Can someone tell me where I am going wrong, because the getChangedAttributes function always returns an empty list (assuming because "backupTable" and "form" contain the same values? But shouldn't they be different?
i have a problem with detailsview as below, when user click on btnEdit, it will call detailsview.changemode(edit) and then allow user to enter data into the textbox, after that user will click on btnsave and then to read the value from txtname and process the value. my question is how do i get the value from txtname? i dont want to use any datasource component and i have tried call the DetailsView1.FindControl("txtname") and it returned txtbox with empty text.

I am binding the ReorderList in my code behind file. I am not using a DataSource Control like SQLDataSource etc. How will I capture the values edited, in my ReorderList1_UpdateCommand(). In GridView we can use something like

View 2 RepliesI have created a web based form which has a drop down list (DDL) that lists various company names. I want to create a box in the form which displays the contact info for that particular company which is chosen in the DDL. Also, I want this info to be in a greyed area so that user cant modify (can just copy it).
what asp tool i should use for this (I am guessing textbox wont be good enough since user can modify the info that populates in it)
How to make the selected record (area) for editing to be in the center of the screen?
I have a GridView with custom Edit functionality. I have panel, table and some controls for updating in the EditItemTemplate area. When the user selects to edit a record, I want the edited record area to be aligned in the center of the screen. What is happening now is, with the gridview having many records; the user has to navigate to find where the edit box displayed!
I have 3 gridviews on my page, all with the same columns. I want the user to be able to click on a button and it export all three gridviews to an Excel file, whether on 3 different worksheets or the same worksheet (preferrably the same, but either will do).
And in code behind, I insert footer rows to total by department, so if I use this
Export to Excel control it will export only 1 gridview at a time and won't export the inserted footer rows separating the departments.
