asp.net - gridview row eval: column as name parameter instead of index -


i have gridview , onrowdatabound event linked function:

if (e.row.rowtype == datacontrolrowtype.datarow) {     thisrow = e.row.dataitem myobjectmodel;      if (thisrow.property1 == null) { e.row.cells[5].text = "-"; }

this code looks @ value of property of object in data source , if it's null, converts null display "-" in column 5. problem i'm having if change order of columns of gridview, need change index of every other modification. i'd change statement "e.row.cells[5].text" says "the cell column header xyz".

any suggestions?

thanks.

i think might better off handling in gridview code rather code behind, if shuffling columns around.

here's example ponies. feel free edit needed.

 <asp:templatefield headertext="likes ponies?">     <itemtemplate>        <asp:label id="uxlikesponieslabel" runat="server" text=’<%#           databinder.eval(container.dataitem, "favoriteponies").tostring() == "" ?          "i " + databinder.eval(container.dataitem, "favoriteponies") + " ponies!" :          "-"          %>’ />     </itemtemplate>   </asp:templatefield>

i'm using c# (boolean condition) ? "value if true" : "value if false" here.

so, code check see if favoriteponies column in particular row "" (because null values displayed empty string) , if so, displays "-" instead. if it's not null, displays in database databinder.eval(container.dataitem, "favoriteponies") "i ponies!".
