Forms Data Controls :: Validating Dropdown Selection In Footertemplate In Gridview?

Feb 8, 2010

I have two dropdowns in the footertemplate of my gridview inside a usercontrol.

I also have a button "btnADD" inside the footer template. I am using the footertemplate to add a new row to the grid.

What do I do to validate on Button_click event for 'btnAdd' if a value is selected in the dropdown other than "select.." which I dynamically add in rowdatabound event?

I have this javascript function that I wanted to implement, but it gets called in the Page_load event rather than the button click event and gives an error.

The javascript function that I need to call is this: ( I created a method to return a string to use it in regards to RegisterClientScriptBlock, but do not know exactly how to use it)

rotected string BuildValidation()
{
StringBuilder sb = new StringBuilder();
sb.Append("<script type='text/javascript'>");
sb.Append("function ValidateWComp() {");

[Code]....

Forms Data Controls :: GridView Page Reset Based On DropDown List Selection?

Jan 3, 2011

i want to see the sales in the grid view based on the month selected from drop down list. Ex: when I select June 2010 from the ddl box, the sales for that month are correctly displayed in the grid view. I go to page 4 to look at some sales there and then switch the month to August 2010 to see sales for that month instead. Here is the problem. When I switch the month, it show August 2010 sales, but stays in page 4 instead of going back/resetting back to page 1 of August 2010 sales.

How do I reset the grid view page back to the first page of August 2010 sales?

I am fairly new to ASP. If I have missed an imp. detail in this post, let me know and I will get that info. out there.

Forms Data Controls :: Validating An Entire Column In Gridview Before Data Is Saved In Database?

Mar 24, 2010

I am using a bound gridview in ASP.NET 2.0. The gridview has the ability to edit/update and insert rows. One of the columns holds a number which represents a percentage. What I cannot figure out is how to ensure that all the rows in the gridview total 100% before being able to send the updates or newly inserted data to the database.

For example say there are 5 rows in the gridview, each row has 20% stored in the column so it adds up to 100% which is fine, the data is updated/inserted in the database. But say each row only had 15% totalling 75%, the user should not be able to send the updated/inserted data to the database until either they add a new row with a percentage of 25 or they edit the other rows for a cumulative total of 100%

I am not familiar with javascript or AJAX

Web Forms :: Populating A Dropdown Box With Contents Based On The Selection Of Another Dropdown Box

Sep 16, 2010

I am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1

I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.

can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?

FYI I am using Visual Studio 2010 and SQL/Server

Forms Data Controls :: DropDownList In The FooterTemplate Of A DataGrid Will Not Show Its Items?

Oct 13, 2010

I am placing a dropdown list in the footer of a DataGrid like this:

[Code]....

In my code behind file, in the myDDL_OnLoad event handler, I call to the database, populate a SqlDataReader, and set the DDL's datasource to that datareader. I define what data columns should be used for the DataValueField and DataTextField of the dropdownlist. Then I call the DropDownList's DataBind() method. Everything works without error. But, when the dropdownlist is displayed, it has blank lines in it.

By that, I mean if 8 records are loaded into the dropdownlist, it will expand to a size appropriate for 8 rows but, it will be empty. there is no text in it.

Has anyone seen this type of behavior before? This dropdownlist is in the footer of a dynamically loaded ajax update panel so, it is difficult to see the source code to see what values are in the html element rendered to represent the dropdown.
