I have a gridview that I am dynamically creating and populating.

myGrid.Columns.Add(new BoundField() { HeaderText = "Serial #", DataField = "serial_number" });
...

myGrid.DataSource = myDS;

Dynamically Adding Controls To A Panel Within A Data Repeater?

Jul 15, 2010

I have a Data Repeater to which I need to add x number of images depending on their existence in the database.

I need the images added within hyperlinks for Javascript functionality. In order to dynamically add the hyperlinks and images I have placed them within a panel in the data repeater and am adding them in the ItemDataBound event.

The problem is that only the first image is being written to the datarepeater.

Forms Data Controls :: Dynamically Adding Rows To A Table

Apr 19, 2010

I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.

Here's the design I want:

ddl1 | ddl2 | ddl3 | ddl4 | ddl5 | ddl6 | ddl7 | textbox

When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.

Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.

Forms Data Controls :: Dynamically Adding Second HeaderRow To GridView?

Mar 15, 2011

I've read a few articles on this, but I keep doing something wrong, and I'm not sure what. I took out all of my customization and just want to add a single header row to the very top of my GridView... Can someone show me how I'm screwing up? This is the code I'm trying to use...

[Code]....

I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls[0], etc, but nothing seems to work.

I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?

(have also tried using "0" for the rowIndex when creating the new GridViewRow)

Forms Data Controls :: ListView With Datasource And Later Adding Items Dynamically?

Dec 11, 2010

I have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.

Forms Data Controls :: Adding Queryextender Expression Dynamically To The Page?

May 12, 2010

I am trying to dynamically add a queryextender expression to the page. something like, when the user clicks a button, we need to add a OrderbyExpression. The following is the code used. It works when added in Page_Load but doesn't when added on a button click event. Upon button click the page just reloads and ignores the filter condition.

OrderByExpression obex = new OrderByExpression();
obex.DataField = "ProductName";
obex.Direction = SortDirection.Descending;
ThenBy tb = new ThenBy();
tb.DataField = "UnitsInStock";
tb.Direction = SortDirection.Ascending;
obex.ThenByExpressions.Add(tb);
this.q.Expressions.Add(obex);

where queryextender1 is the ID of the queryextender

Forms Data Controls :: Adding Spaces In A String Which Is Generated Dynamically In C# Code?

Jul 20, 2010

I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:

string s1 = "string1";

string s2 = "string2";

And then I have a header cell text which needs to be populated like this.

headercell.text = s1 + new string(' ', 20) + s2;

I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.

I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.

Forms Data Controls :: Adding Values From Different Database Rows To A Dropdownlist?

Feb 11, 2010

Is it possible to add values from different database rows to a dropdownlist?

I'm currently trying to add both ItemSizeSmall and ItemSizeMedium, but through trial and error I can still only add one row from the database. I want the dropdownlist to display "Small" and "Medium" etc.

I guess my primary question is: How do I create a database with product size attributes?

I apologize if this thread should be in another forum, but if the dropdownlist can display two database rows I'll settle with that solution.

Could the database look like this:

table1: product
PK: productID
table2: productAttribute
PK: productID
PK: attributeValueID
table3: attributeValue
PK: attributeValueID
FK1: attributeNameID
table4: attribute
PK: attributeNameID
name

If this is right: How do I make the dropdownlist display the different sizes?
