View 1 RepliesI have a gridview that I'd like to have changed based on a value selected in a dropdownlist. I'm able to get the aspx page to display the dropdown list (comming from SQL), and when I select a value, the page reloads, but no data show in the griview.

if i give the 10 number,10 number of same images should be diplayd in the Grid View.
how can i do that.
i m displaying an image in gridview based on condition from sql table. That is if the colum named "availabillity" is A the image will be red n if the value is "NA" the image will be green. i am using RowDataBound event.
but i am getting error as "Cannot implicitly convert type 'System.Web.UI.WebControls.DataControlRowType' to 'bool'".
I'm new to web dev and c# so please bare with me. I am trying to create a dynamic gridview in a web form for users to to answer questions with (code below).
The dificulty im having is that i am nesting a dropdwonlist in the gridview and want to be able to dynamically set the list values based on parameters (of the row they are on). These values are in the main dataset for the gridview as each row represents a questionid and question text and then a ddl for the criteria...
I just don't know how to set the values for the dropdown all the code so far is below... just need to be able to populate the dropdowns with the relevant values.
I have created a stored proc to return the different criteria based on the questionid and questionGroupid which is the dataset that populates the other fields in the gridview: dbo.usp_QuestionCriteria @QuestionGroupId, @QuestionId
I have added this as a tableadapter called criteriaTableAdapter in a xsd file as well using the wizard... not sure if this is the right option though or just use the same method as i have for the other stored procedure as in the code below:

I'm having trouble figuring out how to display a gridview based on the selection of a drop down list. I manually entered the drop down list items, but in the configure/choose data source I don't understand how you make a relationship between each list item and the corresponding database table you want to show.
View 7 RepliesI have two tables Emp,Dept
EMP Â Â Â Â Â Â Â Â Â Â Â Â Â DEPT
EmpNo(PKEY) Id(FKEY) to Empno

I want to display Gridview columns like this ....
E.Fname,E.Lname,D.date based on Id
(or)
Display E.Fname,E.Lnamebased ob Id
GridViewDetails uses templatefields. In edittemplate I put a button called "ButtonUpdateAdjustAmount" with OnClick="Update_AdjustAmount" in the EditItemTemplate for the "Amt to be Adj" column. There is also a textbox. My user's should be able to edit the textbox, but I also want the ability to click the button and the textbox populated with the correct calculated value. The formula varies based on the "code" column which is a dropdownlist called "DropListCode".
I am fairly new to asp.net, vb, etc...so forgive my code writing. Eventually I need to also put the same functionality on the insertrow for my gridview. But first wanted to get the edit one working. I am using templatefields for all columns and the FooterTemplate to perform the Insert New Detail Line.
I can get the functionality to work for the first data row and only if I take out the If code.SelectedValue = ... line and leave 1 static formula. However that isn't going to work. If DropListCode.SelectedValue is DNR then AdjAmt should be ((q_ordered - q_received) * cost). If DropListCode. SelectedValue is OV then AdjAmt should be (RKNumber * cost). If DropListCode.SelectedValue is NB the AdjAmt should be ((q_received - q_ordered) * cost). If DropListCode.SelectedValue is DAM then AdjAmt should be (RKNumber * cost)

To what extent our institution is useful for you  Dropdownlist1(Good/Poor).When user select the Poor form the Dropdownlist1 in that case ONLY POPUP screen will be displayed.The POPUP Screen as follows
         Textbox (In that textbox user type the reason for Poor)
            Submit(Button)
When user Click the Submit (Button) the selected dropdownlist and Remarks will be displayed in the Gridview. The Gridview as follows
       Dropdown      Reason
                0                      The institution has to be improved for lot
instead of Select the Good from dropdownlist1, user wrongly select the Poor from the dropdownlist. that time POPUP screen is to displayed.(Only when user select the Poor from the Dropdownlist POUP Screen is to be displayed in that textbox type the reason and click the Submit Button). Then Gridview as follows
       Dropdown      Reason
                0                      The institution has to be improved for lot
Then user again select the Good from the Dopdownlist1 means Previously value in the Gridview.Dropdown and reason has to be deleted in the Gridview.for that how can i do using csharp.

My database has 4 colums;
TraditionalID-------------TraditionalName------------Singles-----------Suppers
Singles and suppers are money fields for the price of same item. A bit like the price of a Small, Medium or Large item. What I would like to do is display the 'Singles' price and 'Suppers' price in seperate listitems so the user can choose 1 of them.
GridView:
Traditional Name__________Size
Chicken-------------------[DROPDOWNLIST]
DropDownList:
Price of Single is: £1.50
Price of Supper is: £2.50
My page loads up with the correct items in TraditionalName colum but the DropDownList is completely empty. I'm aware I don't have anything in for DataValueField and DataTextField but I have tried putting things in these attributes, like Suppers and Singles, but nothing works, so I have taken them out below.

I have a web form with two drop downs.I want the gridView to display the data based on one or the other.The user can then select a record to be displayed in a detail view.This method works as long as I am only viewing the data.If the user edits the data in the detail View and then updates the detail view when the page reloads the grid goes blank.I have traced the code and there is data in the query after the update but the select statement for the LinqDataSource is overriding the code in the lqGrid_Selecting.I can make the above scenario work using SqlDataSources,but I thought LinqDataSources were the way of the future.
