Visual web developer 2010 express; made a simple web page ( tables and text; that went fine) added a data grid; easily seen in design view, but not there at all in debug.
View 2 Replies
I recently upgraded from VWD 2008 Express to VWD 2010 Express. A problem has developed in that the website's graphics no longer appear in Design mode, there are "Error Creating Control" error messages that did not exist before, and also debugging errors that did not exist before. (Note: these problems did not exist when I first used VWD 2010; they may have originated with recent automatic Windows updates (I use Vista Home Premium SP2 with IIS 7)). The problem exists if I open the website either as a project file or as a website directory.

I've wrote the comprehensive post within my blog: [URL] In brief words everything is simple:
1. I've downloaded free Visual Studio C# 2010 Express and Visual Studio Web Developer 2010 Express
2. I've successfully installed these versions.
3. I've tried registration online - and got the appropriate keys which I've used for registration.
Finally all the keys I've got are not valid for the system - and after 30 days evaluation (for free version?) period all these products are not running anymore because all the keys I am providing from online registration are invalid.
I am trying to make columns of a gridview invisible if they contain a space. The page contains a combo box which users can change. This causes a change in the data in the gridview. I use the following code:
[Code]....
[Code]....
What is working: On the initial page load, the correct columns are deleted. However, if the user changes the combo box, and the gridview has different data loaded into it, it cannot make visible what was previously invisible. I added the ...visible = true line to get round this, but when I load the page, it seems to get locked into a loop forever, and the page never loads - this is why the line is commented out.
This should be soooo simple, but it's making my brain smoke. I've tried writing the results on whether there is a space in the cell to an array, and then using that to make the columns invisible. I've tried doing this in different events, but it always has the same problem.
I suspect that if I can find out how to reference the contents of the gridview from outside its events, it may be easier.
i have one grid and one button when i click on that button then it expand and showing another grid under the row of parent grid how to do that.

View 1 RepliesI am trying to update my Fromview Delete button to Visible = false, if a record in another related table is inhabited.
But I keep getting errors, or it is still visible even though I know that there is not a record.
[Code]....
So here is what happens, First the Gridview sets the pageIndex of the Formview then
I want it to read from the customer_contacts table and if the SelectedValue (LocationID) is in a table ie if there is a contact assigned to this location, I don't want them to be able to delete the location until they have reassigned the contact to a new locationID, and If there is only 1 location on record, they cannot delete either.
I have a formview which contains a question and 5 checkboxes with answers alongside. Some of the questions are true/false so I want to make checkboxes 3, 4, and 5 invisible.
Should this be handled in code-behind? (I don't see any ready-made events for paging through the formview) or is there a way to test data and change the visible property in;
<asp:CheckBox
ID="CheckBox3"
runat="server"
/>
<asp:Label
ID="QA3Label"
runat="server"
Text='<%#
Bind("QA3") %>'
/>
I m getting 9 columns from database in a dataset but I want to diplay only 4 columns in datagrid. Remaining 5 columns values, I want to display in the textboxes below datagird.
I tried it making column invisible. If I make it invisible, I m not getting any value for that column to display in the textbox.
let me explain completly. I designed an gridview, header template i added one textbox and button if the user enter something on Txtbox and click button then based on input i show corresponding rows only, all other rowss will be hidded using Javascript like below
tblOrders.rows[CurrRow].style.display = 'none';
now im doing something on the Gridview_RowCommand event at this time the gridview got refreshed so that the hiden rows are visible, but i dont want to show the hidden(invisible) rows while rowcommand event fired.
If a session variable is set to a certain value, I would like to make a href link invisible.

I have a gridview that is being populated off of a query that has joins in it. It works fine. However, I want to display one record of all information but then blank out all colunmns accept 1 for the other 3 records that it is picking up. In other words, right now, all three records have duplicate info in them accept this one column. can this be done? Can I somehow blank out other columns based upon what is in the single column? This is all being done in a gridview. I realize it would do a master detail type scenario but I want all of this information to display without someone having to click on a field or anything.
View 4 RepliesI've run into this before, but I was using a formsview and just changed the field to hidden. I am trying to get the value of a cell out of a gridview to a variable and here is the code:
[Code]....
This works perfectly if column 6 is visible, but because it's an id number (which is not the primary key) I do not want it visible, but changing it to visible="false" causes this code to return null. Changing it back to visible and it works.
I'm not sure why the visiblity of a control changes the functionality of it.
In Visual Web Developer-2010, I have been trying to connect to IBM DB2 Database after installing the DB2 9.7 client (both supports VS2010/.Net4) so that I can use "ADO.NET Entity Data Model", but while clicking "New Connection" I can only see the list of Data Sources and Data Provider only related to MS SQL server. This is totally blocking my work, I am not able to work further since I cannot even establish the connection to my db2 database using this new editor so that I can create the edmx files in the solution for non MSSQL databases. Kindly provide me the solution ASAP, since my further work is blocking due to this.

I have a Gridview with some template columns. Inside one of the columns, I have a ImageButton with a serverSide OnClick handler to show or hide a panel. And all the panels by default are hidden. What happens is that when I click the imageButton the first time the panel gets displayed, but if I click the same button, on the same row again, - where the panel is now visible - the panel doesn't hide itself. Here's what happens when the imageButton is clicked:
protected
void ImageButton1_Click(object sender,
ImageClickEventArgs e)
{
ImageButton imgBt = (ImageButton)sender;
Panel compRecDetails = (Panel)imgBt.NamingContainer.FindControl("CompanyRecDetailsPanel");
if (compRecDetails.Visible ==
false)
compRecDetails = true;
else
if (compRecDetails.Visible ==
true)...............................
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;
